Definition and Function
What Is a Camshaft?
Shop for precision-engineered Camshafts designed to restore or enhance engine performance.
A camshaft is a fundamental internal engine component responsible for the precise timing and operation of the intake valves and exhaust valves.
This rotating shaft features a series of carefully shaped lobes that, as they rotate, push open the valves, allowing the air-fuel mixture to enter the cylinder and exhaust gases to exit.
The exact shape, size, and timing of these lobes dictate the engine's power band, torque characteristics, and overall efficiency.
Without a properly functioning camshaft , an engine cannot run correctly, making it one of the most critical spare parts for any complete engine overhaul or performance upgrade.
OEM and Aftermarket Camshafts
Choosing the Right Option
When you decide to buy a replacement part, you will encounter two primary categories: OEM and aftermarket Camshafts.
- OEM (Original Equipment Manufacturer) Camshafts are designed to be a direct, factory-spec replacement for your vehicle's original part.
They are the ideal choice for standard repairs, restorations, or when you want to maintain the vehicle's original performance and driving characteristics.
- Aftermarket Camshafts, on the other hand, are engineered to alter and often improve engine performance.
These are popular among enthusiasts and builders looking to increase horsepower, torque, or shift the engine's power band to a higher or lower RPM range, catering to specific applications like racing, towing, or enhanced fuel economy.
Camshaft Specifications
Lift and Duration
The key to unlocking performance with an aftermarket camshaft lies in its specifications, primarily lift and duration.
"Lift" refers to how far the valve is opened, while "duration" refers to how long the valve remains open.
A performance camshaft with higher lift and longer duration allows more air and fuel into the engine, resulting in a significant power increase, especially at higher RPMs.
Different profiles, from mild "street" cams to aggressive "race" cams, are available.
Choosing the correct profile is essential, as a camshaft designed for a race track will perform poorly in a daily-driven vehicle, sacrificing low-end torque and drivability.
Finding the Right Camshaft
Vehicle Compatibility and Application
Selecting the right component is crucial for achieving your goals.
To find the best Camshafts for cars, trucks, or SUVs, you must consider your engine type (e.g., V8, inline-6, 4-cylinder), your vehicle's primary use, and what other modifications have been made.
A camshaft for a heavy-duty diesel truck built for towing will have a completely different profile than one for a lightweight sports car intended for high-RPM power.
Our catalog makes it easy to find a compatible part by filtering by your vehicle's make, model, and engine.
Ensuring compatibility is the first step to a successful and reliable engine build or repair.
Signs of a Worn Camshaft
Common Symptoms
Knowing when to order a replacement camshaft is key to preventing catastrophic engine failure.
The most common symptom of a worn or failing camshaft is a persistent ticking or tapping sound from the top of the engine, which increases with engine speed.
Other signs include a noticeable loss of engine power, rough idling, engine misfires, and a check engine light with codes related to camshaft position or cylinder misfires.
Worn lobes can severely impact valve timing, leading to poor performance, reduced fuel economy, and eventual damage to other valvetrain components like lifters and rocker arms.

Installation Recommendations
Related Components to Replace
Proper installation is as important as the quality of the part itself.
A camshaft replacement is an advanced mechanical task that also requires the inspection and often the replacement of associated components.
To ensure a successful installation, it is highly recommended to also replace the lifters (or tappets), as a new camshaft should always be paired with new lifters.
Additionally, inspecting valve springs, timing chains or belts, and tensioners is crucial.
Using the correct assembly lube on the lobes and journals during installation is vital to prevent premature wear during the critical initial engine startup and break-in period.
Final Recommendation
Restore Engine Performance and Reliability
Ultimately, the camshaft is the heart of your engine's valvetrain, directly controlling its breathing and personality.
Whether you are performing a necessary repair or undertaking an exciting performance build, choosing the right camshaft is a decision that will define your vehicle's performance for years to come.

FAQ
What is a camshaft and what does it do?
A camshaft is a critical engine component that controls the opening and closing of the intake and exhaust valves. Its precisely shaped lobes determine valve timing, which directly affects engine power, torque, efficiency, and overall performance.
What is the difference between OEM and aftermarket camshafts?
OEM camshafts are designed to match the original factory specifications of your vehicle and are ideal for standard repairs or restorations. Aftermarket camshafts are engineered to modify engine characteristics and can improve horsepower, torque, fuel economy, or performance for specific applications such as racing or towing.
What do camshaft lift and duration mean?
Lift refers to how far a valve opens, while duration refers to how long the valve remains open. Higher lift and longer duration generally allow more air and fuel into the engine, which can increase performance, particularly at higher RPMs.
How do I choose the right camshaft for my vehicle?
The correct camshaft depends on your engine type, vehicle application, driving style, and any existing engine modifications. A camshaft designed for a race engine will perform differently than one intended for daily driving or towing applications.
What are the signs of a worn or failing camshaft?
Common symptoms include ticking or tapping noises from the engine, rough idle, engine misfires, reduced power, poor fuel economy, and check engine light warnings related to camshaft timing or cylinder misfires.
Why is camshaft compatibility important?
Using an incompatible camshaft can lead to poor engine performance, incorrect valve timing, and reliability issues. It is important to select a camshaft that matches your vehicle’s make, model, engine, and intended use.
Should other components be replaced when installing a new camshaft?
Yes. It is highly recommended to replace lifters or tappets when installing a new camshaft. Inspecting valve springs, timing chains or belts, tensioners, and related valvetrain components is also important to ensure long-term reliability.
What materials are high-quality camshafts made from?
Premium camshafts are commonly manufactured from hardened iron or billet steel and are precision-ground to exact specifications. These materials provide excellent durability, wear resistance, and long-term engine performance.
