Product Details

The COMP Cams K12-552-4 Nitrous HP K-Kit is a complete camshaft upgrade package designed specifically for nitrous oxide applications in Chevrolet small block engines. This hydraulic flat tappet cam delivers 212°/222° advertised duration with aggressive lift profiles optimized for maximum power under nitrous injection.

Complete K-Kit Includes:

  • Hydraulic flat tappet camshaft with nitrous-optimized profile
  • Hydraulic lifters engineered to match cam specifications
  • High-performance valve springs rated for increased lift and RPM
  • Hardened steel retainers for reliable valve train control
  • Precision valve locks (keepers) for secure retainer installation
  • Valve stem seals to prevent oil consumption
  • Timing chain set for accurate cam timing
  • Assembly lube for proper break-in procedure
  • Installation instructions and COMP Cams decals

This camshaft kit is engineered for street/strip applications where nitrous oxide systems are used to deliver instant power gains. The duration and lift specs provide excellent throttle response and strong mid-range to top-end power, while remaining compatible with stock cylinder heads and valve train geometry. The complete kit eliminates the guesswork of component matching, ensuring all parts work together harmoniously for reliable performance.

Application: Chevrolet Small Block V8 engines (262-400 cubic inches)

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Very easy to talk to on the phone and excellent service.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Easy and fast. Order arrived very fast. Thanks.
