A Quick Comparison Of Our Top Picks
How we picked the camshafts?
We scoured the internet to see the camshafts with good reviews and came up with a list of about 50. Then, we engaged different professional mechanics from that list to know which were the best from the 50 for the 5.7 L Hemi. From there, we narrowed it down to the eight we have reviewed below.
What is a camshaft, and what does it do?
But before we jump into the reviews, what is a camshaft, and what does it do? A camshaft is a metallic rod typically positioned above the cylinder banks. This rod usually has lobes on its surface that are referred to as cam lobes.
The purpose of the camshaft is to control the amount of air-fuel mixture that enters the combustion chamber. Also, it regulates how the burnet exhaust gas leaves the chamber to make way for the next combustion cycle.
The camshaft is usually connected to the crankshaft using a timing chain or belt. The crankshaft, on the other hand, is responsible for the movement of pistons inside the cylinders. This connection is therefore essential in achieving accurate timing.
Should I replace/upgrade my vehicle’s camshaft?
Realistically, camshafts don’t wear out quickly, and chances are if you have to replace your car’s stock cam. You will also have to replace the entire engine. So why would you replace or upgrade the camshaft?
The main reason why you would want an upgrade is to improve the performance of your car. Upgrading the camshaft will give your engine a boost in performance. This is done to improve the valve timing and overlap. When you swap a camshaft you may also want to change the oil pump.
Causes of camshaft sensor damage
The camshaft position sensor or camshaft sensor is an electric sensor whose primary job is sending data to the Engine control module on the camshaft’s speed. Unfortunately, this sensor can become worn out or damaged over time. So what are some of the causes of camshaft sensor damage?
- This sensor can wear out over a long time of usage. It can also be damaged by moisture damage and oil buildup on the engine.
- If your vehicle is involved in an accident, this can cause damage to the sensor wires and stop them from working.
- An oil leak caused by a defective gasket or loose oil cap can cause signals from the sensors wires to be interrupted.
- The sensor can also be damaged due to damage to another related component of the engine.
Do you know one of the many reasons your engine may be misfiring is a bad camshaft position sensor? But that’s not only the reason for the misfire. If you are experiencing a misfire you may think of checking or changing the spark plug, because that’s the primary reason. We have reviewed the best spark plugs for 5.7 hemi you can find great alternatives from that list.
Types of camshaft
Camshafts can be classified into two main categories, rollers, and flat tappets. However, these two types can be further categorized into hydraulic and solid camshafts. Therefore, these four are the main types of camshafts.
Flat tappet camshafts:
The lifters used in a flat tappet camshaft have a flat surface while the lobes are slightly tapered. The tappet rides against the camshaft’s lobes while the lobes cause the lifters to spin.
In older car models this type of camshaft typically used an early style oil pump.
These feature a wheel and axle arrangement. The wheel attaches to the lifter body and is supported by needle bearings. While the lobes on this type of camshaft are flat, they are thicker than those of a flat tappet camshaft.
These types of camshafts have a hydraulic mechanism that allows them to self-adjust for zero valve lash. This makes them durable and lasts for long, and are common in most vehicles. The one downside to these camshafts is that they can limit an engine’s power output at higher RPMs.
Unlike hydraulic camshafts, solid ones do not have any mechanism or moving parts. Therefore, there is no internal mechanism to compensate for clearance. They tend to be used mainly in performance engines.

Best 5.7 l Hemi camshaft buying guide
Suppose you want to boost the performance of your engine by replacing the camshaft. In that case, there are several things you should consider before investing in one. Below are the main things to consider when shopping for a replacement camshaft.
Compatibility with your vehicle
It goes without saying, but not all camshafts are designed for the 5.7 l Hemi engine. Therefore, the number one thing to consider is compatibility. Check what vehicle models a camshaft is compatible with first before purchasing.
Most online stores will have a compatibility feature for you to check whether a specific component is compatible with your car model.
Since the primary reason you would want to buy a camshaft is to improve your car’s performance, the performance impact of a camshaft is the next thing to consider. The best towing cam for 5.7 ram Hemi will improve your truck’s torque and horsepower.
Usually, a higher RPM rating will be indicative of a camshaft’s performance rating. As such, it is recommended to consider camshafts that can withstand higher RPMs.
Also referred to as lobe displacement angle, lobe separation is the distance between the exhaust and intake valves. The opening and closing of these two valves are crucial to the optimal performance of the engine.
Typically, the best cam for 5.7 Hemi ram will feature a wider lobe separation. This allows for better closing and opening of the valves, which in turn results in more horsepower.
The installed centerline angle
This is the measurement of the position of the crankshaft versus the timing of the camshaft. This measurement is measured in crank degrees from TDC. Also, the camshafts intake love reaches max lift at the ICA.
Where is the camshaft sensor located?
Typically this sensor is located on the engine block or the cylinder head in most vehicles. However, it is essential to check your car’s engine manual for the exact location. For example, in the 5.7 Hemi, the sensor is located under the alternator. This means it is located on the right-front side of the engine on the timing chain cover.
Difference between camshaft and crankshaft
A camshaft uses its egg-shaped cam lobes to open and close the engine valves. This is how it controls the air-fuel mixture entering the combustion chamber. On the other hand, the crankshaft harnesses the power generated from the combustion chamber into rotational movement.
As mentioned, these two are connected via a timing chain and sprockets. The two are connected at a ratio of 1:2. This means the camshaft rotates once for every two rotations of the crankshaft.
How long are camshafts supposed to live?
The camshaft is a part that should last you the entire lifespan of a vehicle’s engine. As such, if the camshaft is worn out, chances are the whole engine is too.
