Performance Camshafts

What Does the Camshaft Do?

The camshaft is a critical component of your engine's valvetrain system. Its primary function is to control the opening and closing of the engine's intake and exhaust valves. This is achieved through the action of lobes or cams on the camshaft that press against lifters, pushrods, and ultimately, the valves themselves.

The camshaft's profile, often referred to as the camshaft's "duration" and "lift," determines the timing and extent of valve opening and closing. In essence, the camshaft dictates how much air and fuel enter the engine's combustion chambers and how exhaust gases are expelled. By altering the camshaft, you can tailor your engine's performance characteristics to suit your needs, whether it's for better low-end torque, high-end power, or a balance of both.

What Happens When a Camshaft Fails?

When a camshaft fails or experiences issues, it can lead to significant engine problems. Some common signs of camshaft issues include:

1. **Reduced Power:** A failing camshaft can result in reduced engine power and performance.

2. **Misfiring:** Irregular camshaft operation can lead to engine misfires and poor combustion.

3. **Rough Idling:** You may notice rough idling or vibrations when the camshaft is not functioning correctly.

4. **Engine Stalling:** In severe cases, camshaft problems can cause the engine to stall or not start at all.

How Much Does a Camshaft Cost?

The cost of a camshaft can vary widely based on several factors:

1. **Type of Camshaft:** Performance camshafts designed for racing or high-performance applications may cost more than stock or OEM camshafts.

2. **Brand:** Camshafts from reputable brands with a track record of quality and performance tend to be more expensive.

3. **Vehicle Make and Model:** Camshaft prices can differ significantly depending on the specific requirements of your vehicle's engine.
