Product Details

The COMP Cams K12-568-4 is a complete high-performance camshaft K-Kit designed specifically for nitrous oxide applications in Chevrolet small block engines. This hydraulic flat tappet camshaft delivers aggressive performance with 240/253 degrees of advertised duration, making it ideal for street/strip builds running nitrous systems.

Complete K-Kit Includes Everything You Need:

  • High-performance hydraulic flat tappet camshaft with nitrous-optimized lobe profile
  • Hydraulic flat tappet lifters matched to camshaft specifications
  • High-pressure valve springs designed for increased lift and rpm capability
  • Steel valve spring retainers for durability
  • Valve locks (keepers) for secure valve train operation
  • Valve stem seals to prevent oil consumption
  • Double roller timing chain set for precise cam timing
  • Assembly lube to protect components during initial break-in
  • COMP Cams decals and detailed installation instructions

This camshaft's 240/253 duration split provides excellent throttle response and power delivery under nitrous activation while maintaining reasonable street manners. The hydraulic flat tappet design offers reliable performance with lower maintenance requirements compared to solid lifter setups. Perfect for enthusiasts looking to maximize their nitrous-equipped small block Chevy with a complete, engineered valve train solution.

Application: Chevrolet Small Block V8 engines with nitrous oxide systems

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Typical. No issues...

So far so good

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
