When you know the things to consider for choosing a camshaft for 5.7 Hemi ram, you can make a better purchase decision. So, let’s look at the buying guide for the best cam for 5.7 hemi ram:


For efficient operation of the engine of the 5.7 Hemi ram, the proper horsepower is essential. Many customers are confused about how much HP does a cam add to a 5.7 Hemi? Well, it varies in each model and you need to look at the detailed specification before making a purchase. Also, some customers ask on can you cam a 5.7 Hemi? Yes, with proper horsepower output and efficiency, it is possible.


If you are purchasing an aftermarket camshaft, you may be attempting to gain the maximum benefit of your 5.7L engine. The performance of a camshaft is essential for the increase in the efficiency of the engine. You can look at the horsepower and the performance rating of a camshaft to get an idea n the performance. Based on your personal preferences along with the amount of torque required to use in a camshaft, the performance may vary.

Your budget decides the type of camshaft you need to buy. Generally, the high-end models provide more torque output, excellent RPM range, and high performance. You can consider paying a high price if you wish for a camshaft with powerful racing abilities. Substituting a camshaft gives a great benefit in many models. For example, it is possible to add nearly 70 HP to a 5.7 Hemi with a cam change. Moreover, with a decent choice, it is possible to cam your Ram – 5.7 Hemi performance cam swap.


One of the most vital factors to take into account before buying a camshaft is the compatibility with your vehicle. It is useless to buy one that cannot work well with your vehicle. Firstly, check the specification of your vehicle and also look at the product details. Checking out the detail is the foremost step in getting the correct camshaft for a vehicle.

Keep in mind that a camshaft is an extremely specific and cutting-edge vehicle part. Hence, it must not be utilized with incompatible vehicles.

Lobe separation:

The lobe separation is the next inevitable factor of a camshaft which you must pay attention to. It is accountable for the efficient functioning of the intake as well as exhaust valves. Moreover, the process of opening and closing such valves is accountable for the efficient working of the engine. If due to a certain reason the lobe separation is not correctly configured then the timing of the intake as well as exhaust valves will be imprecise.

In some unfavorable cases, this can lead to the malfunctioning of the engine. Hence, the lobe separation is important to consider before investing in a particular camshaft. In the product specification, you will find the info on the lobe separation and the way it functions. If it is not mentioned then you can consider that the lobe separation is based on the purpose, displacement, and compression ratio of the engine.

Types of cams for 5.7 Hemi Ram:

Based on the way they cooperate with the lifter, it is found that there are two available types of camshafts for 5.7 Hemi Ram. The same are discussed below:

i. Roller Cam:

The roller cam does not need spinning to reduce wearing out. When compared to flat tappets, it is observed that the roller cams offer a higher powerband. Furthermore, it can have larger spring load acceptance. The key benefit is its excellent performance without any chances of premature engine failure.

ii. Flat Tappet:

This second type of cams has a surface that looks like a flat plane. Usually, they have limited RPM and spring load. However, if you want to use them for obtaining high performance then you need to compromise with their lifetime. Moreover, with a less complex design, these flat tappets are relatively less costly.

Now, these two types of cams come with two available options.

Solid cams- The solid cams feature an accurate transmission of the camshaft profile towards the valvetrain. The same allows these cams to attain a higher powerband when compared to the one in the hydraulic cams. However, regular maintenance is essential else it becomes worn out. Occasionally, it can lead to damage to the engine.

Hydraulic cams- Through a lash-free valvetrain, these cams work quietly and require less maintenance. However, the disadvantage is they come with a limited RPM range i.e. maximum up to 6500.

Why Should You Get Your Car a Cold Air Intake System?

Why would you need a cold air intake system to upgrade your car? It has to do with how the engine works. They call it the combustion technique, a way for the internal combustion engine to turn the pistons. As you probably know, the inner combustion engine draws in air and fuel, igniting using a spark plug (gasoline engines).

It results in the needed pressure for the car to move forward. You need two things for the engine to perform at its horsepower – more air and fuel. One method of doing this is by modifying the motor, so it sucks in more air. More air means the injectors need more fuel, and that equals more horsepower.

You ask yourself, ‘how can I get more horsepower out of my 5.7 Hemi? The answer is by installing a cold air intake system. It will help your Chrysler Hemi engine to get more air, thus more fuel, and more horsepower. Besides increasing horsepower as well as torque, your engine also gets a greater sound.

What Benefits Do a Cold Air Intake Offer Your 5.7 Hemi Charger?

There are plenty of benefits to a cold air intake and among them are:

  • More Oxygen

The most obvious benefit if you install a cold air intake kit is more oxygen to the engine. If it gets more air, that means more combustion when it mixes with the fuel in the cylinder. As mentioned, this will result in more horsepower.

  • More Power

It has already been mentioned that with cold air intake, your car’s engine gets increased combustion leading to high horsepower and torque. As a result, your vehicle enjoys better horsepower gain and throttle response, not to mention it can tow more weight.

  • Reusable Filer

A car’s standard air filtration system has a disposable filter. If you get the best cold air intake system, they usually come with reusable filters. You can remove and clean them when needed, allowing you to save money. They are also environment-friendly.

  • Fuel Economy

It’s also been mentioned before how cold air in the engine helps not only boost power but fuel efficiency. With the increased combustibility of the engine, you need less fuel to expend the same amount of power. 

As you can see, the best cold air intake for 5.7 Hemi Charger is an excellent upgrade. It’s a good investment if you want to improve your car’s performance. You can get more oxygen, more power, better fuel efficiency, not to mention eco-friendly filters.

Things to Consider When Looking for the Best Cold Air Intake System

How do you find the best cold air intake for 6.4 Hemi Challenger? What about your 5.7 Hemi Charger? Or any other engine for that matter? Start your search by understanding the following factors that affect a cold air intake system.

  • Compatibility

The most important thing to consider when you purchase a cold air intake system is compatibility. You have to make sure that it matches the year, make, and model of your car as listed by the manufacturer. If you try to fit an incompatible cold air system kit, it can damage your vehicle and its system.

  • Oiled Filter Element

An oiled filter element has some good benefits. However, this can cause failures or malfunctions in the air intake unit. The problem you will likely encounter here is the build-up of microscopic oil particles contaminating the airflow meter. One way to reduce or remove this problem is the use of a dry filtering element.

  • Water Ingestion

Any water that gets into the air intake system does not only negatively affect the vehicle’s performance. It may damage the system as well. See if your car’s air intake system is at the bumper’s bottom part or if there is often standing water left in your area. Those things should tell you what to do to avoid water from getting into it.

  • CARB Approval

This factor has something that relates to the law in your state. In California, you can’t operate a vehicle with a modified intake or exhaust system without the California Air Resource Board approving and certifying it. There might be similar laws in your state. If you don’t, it can result in your car getting impounded or a fine.

Keep this in mind when you shop around for the best cold air intake system for your vehicle. It should help you find the one that will make the best upgrade to your car and boost its performance on the road.

Choose the product with tubing made of any of these materials. 

  • Mass Flow Sensor

There’s only one reason why your cold air intake system has a sensor – so you know how much air mass gets into the engine. When you know the air mass flowing through the intake, you can calibrate how much of it that the engine needs. With that, you can maximize the performance of your car. On that note, your two main options for a mass flow sensor are a hot wire and a vane meter.

  • Thermal Barrier

A thermal barrier is crucial to maximize the benefits you get from installing an air intake system. The barrier is what will protect the engine from thermal contamination. If you look for a cold air intake system, look for the one with a barrier made of the best materials like carbon fiber or zirconium.

  • Fender Mount

Another feature you might want in your cold air intake system is the fender mount. It’s an innovative solution that helps further cool the engine’s airflow. You can get the most out of your car’s cold air combustion, thanks to this.

Factors to Consider When Looking for the Best Aftermarket Headlights for Silverado

It is not easy to find the right aftermarket headlights for your Chevy Silverado. The biggest hurdle is your car itself. The Chevrolet Silverado has been around for decades, so there are many different models available. Thus, it can be overwhelming to find which headlights are for your specific Chevy Silverado, especially if you are an inexperienced customer.

But don’t worry. Below are some things that can help you when shopping for the best aftermarket headlights for your Chevy Silverado:

  • Your Specific Chevy Silverado Model

The first factor to keep in mind is, of course, the specific model of your Chevy Silverado. Everything else will be useless if the kit you bought is not compatible with your vehicle. With that being the case, start getting to know your model. Consult with a mechanic if you are unsure what model your Silverado is to understand what headlights fit it.

When you finally know the exact model of your Chevy Silverado, then you can be confident in buying the right aftermarket headlights. That being the case, remember to look at the compatibility of all the headlights mentioned above. That way, you can be sure that you buy the one that will fit your Silverado.

  • Brand and Quality

Many brands are offering a wide array of headlights kit for Chevy Silverado. If you want the best, you should look at the most renowned and reputed brands known for quality headlights. The top brands for aftermarket headlights are AUTOSAVER88, D.N.A. Motoring, DEPO, Auto Dynasty, and Spyder Auto.

  • Brightness

Check the lumens of your choice of headlights, which measures the brightness you can see at the necked eye. A bulb with more lumens is a bright bulb, so better choose that one. Of course, do not forget to select the significantly durable headlights. You want them to be able to take on the rough road conditions.

  • The Type of Light Bulb

One critical factor to consider when looking for aftermarket headlights is the type of bulb. It is best to get a light bulb that is bright and reliable, especially at night and during harsh weather conditions. Your available choices include:

  • L.E.D. – It is the latest option available and is highly energy efficient. It can produce bright light even though it uses less power.
  • Halogen – They are long-lasting and produce reasonable brightness but are less energy efficient.
  • Xenon – These bulbs are more modern, durable, and energy-efficient. They also produce a brighter light than halogen.
  • Installation

It is best to choose headlights that are easy to install. Some might need drilling or modifications, but most are plug-n-play or bolt-in. These types are easy to mount even if the unit did not include installation manuals. Easy to install headlights mean you do not need an expert installer to mount them.

  • Style and Looks

Since you are already upgrading your Chevy Silverado’s factory headlights, it would be great to get new ones that look great. Of course, choose those that go with your style and preference. That way, you can boost the appearance of your Chevy Silverado while also improving its illuminating ability.

  • Budget

Last but not least, consider your budget. Remember this one rule – you get what you pay for – which means cheap headlights are likely cheap in quality as well. You may be able to find budget-friendly ones that are great, but that takes careful shopping. But if you want to get the best, know that it will be quite a sum of money.

What Is A Lunchbox Locker And How Does It Work?

In the market, there are various types of lockers available and each works uniquely. Out of them, the lunchbox lockers are beneficial to those who are on a budget. Its name -lunchbox originates from the fact that you pack different lunches within the same reusable box. Actually, in this case, the stock carrier is in the box and the locker is present in the lunch.

A lunchbox locker is uniquely designed to uniformly divide power between both wheels. This happens irrespective of which wheel possesses traction. However, it needs to stay open in normal driving situations to make sure the differential work effectively. The lunchbox lockers are also famously known as drop-in lockers.

The below section shows how a lunchbox locker works:

Inside a lunchbox locker, the hole in which the center pin passes through is not shaped like a perfect circle but it is shaped like an oval. Whenever torque is exerted, it forces the pin to shift slightly. Whenever the pin shifts, it pushes the cam gears inside the axle gears. Hence, they lock together.

When no torque is applied, the pin regains to the middle of the oval. After that, it stops pushing the cam gears towards the outside. As a result, the cam gears will spin over the axle gear and this will make the ratcheting noise. The lunchbox lockers are well-known for making this noise.

Whether it is warm or cold air, the air filter is the most important component. It keeps away dirt, dust, and other particles outside the combustion chamber.
