Product Details

The COMP Cams K12-560-4 Nitrous HP K-Kit is a complete camshaft upgrade package designed specifically for nitrous oxide applications in Chevrolet Small Block engines. This comprehensive kit delivers aggressive performance with 224/236 degrees of advertised duration, providing the power characteristics needed for nitrous-equipped street and strip engines.

Complete K-Kit Includes:

  • Hydraulic flat tappet camshaft with nitrous-optimized profile
  • Hydraulic lifters matched to camshaft specifications
  • High-performance valve springs designed for increased valve lift
  • Steel retainers and precision valve locks
  • Valve stem seals for proper oil control
  • Timing chain set for accurate cam timing
  • Assembly lube for proper break-in
  • Installation instructions and COMP Cams decals

This K-Kit eliminates the guesswork of component matching by providing every valvetrain component you need in one package. The Nitrous HP profile features a duration and lift curve specifically engineered to work with nitrous oxide systems, delivering strong mid-range torque and top-end horsepower. Ideal for street/strip applications where nitrous injection provides on-demand power.

Application: Chevrolet Small Block V8 engines with hydraulic flat tappet valvetrain.

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

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.

PARTS WERE CHEAPER THAN MOST

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