Product Details

The COMP Cams CL12-422-8 Xtreme Energy hydraulic roller camshaft and lifter kit is engineered for Chevrolet small block engines seeking improved mid-range torque and increased horsepower. This complete kit features a 218/224 duration camshaft profile that delivers strong performance gains from idle through mid-range RPM, making it ideal for street performance applications, towing, and daily drivers that demand more power without sacrificing driveability.

Camshaft Specifications:

  • Advertised Duration: 268°/280° intake/exhaust
  • Duration at .050": 218°/224° intake/exhaust
  • Valve Lift: .480"/.480" with 1.5 rocker ratio
  • Lobe Separation Angle: 110°
  • Hydraulic roller design for reduced friction and increased efficiency
  • Optimized for stock to mildly modified engines (1,500-5,500 RPM range)

Complete Kit Includes:

  • Xtreme Energy hydraulic roller camshaft
  • Assembly lube for proper break-in
  • Installation instructions
  • COMP Cams decals

The Xtreme Energy series utilizes advanced lobe profiles that maximize cylinder pressure and optimize valve timing events for superior throttle response and power delivery. The hydraulic roller design reduces valvetrain friction compared to flat tappet cams while eliminating the need for break-in procedures. This kit is compatible with both carbureted and fuel-injected Chevrolet small block engines and works with stock valve springs and other components in most applications, though verification is recommended for modified engines.

I purchased a BakFlip F1 truck bed cover, they had the best price I could find anywhere. Their shipping process is very fast. I will look to buy from them again.

So far so good...

Ordered a Rampage frameless soft top for my Jeep. Smooth as silk. Price was outstanding. Order was processed and shipped very quickly and top arrived as adverstised. I would certainly do business with Autoplicity again!

Best prices on the net! They had everything I needed at one site.
