Product Details

The COMP Cams SK12-419-8 Nitrous HP camshaft kit is specifically designed for small block Chevrolet engines running nitrous oxide systems. This hydraulic roller camshaft features aggressive 236/248 duration specs optimized to work with nitrous applications, delivering strong mid-range to top-end power while maintaining excellent streetability.

Camshaft Specifications:

  • Intake Duration: 236 degrees
  • Exhaust Duration: 248 degrees
  • Hydraulic roller design for reduced friction and improved durability
  • Nitrous-optimized lobe profiles for enhanced power under spray
  • Ideal for street/strip applications with nitrous systems

Complete SK-Kit Includes:

  • Hydraulic roller camshaft
  • Hydraulic roller lifters (16)
  • Timing chain set
  • Assembly lube
  • COMP Cams decals
  • Complete installation instructions

This complete small kit provides everything needed for a professional camshaft installation, eliminating the guesswork of sourcing compatible components. The hydraulic roller design offers superior valvetrain stability and longevity compared to flat tappet cams, while the nitrous-specific grind ensures your engine responds optimally when you hit the button. Perfect for small block Chevy engines in street performance, drag racing, and nitrous-assisted applications.

Great prices. Fast shipping. Huge inventory.

Best price on VP fuel jugs and way fast shipping

Fantastic price, positive communication, arrived before promised worked out great!

My experience with autoplicity was great. Great selection and service. Fast shipping. Will definitely use them again.

Initially I was somewhat disappointed with this site's turnaround between the purchase and shipping dates (aprox 3 days) on my merchandise. After vocalizing about the issue autoplicity's customer service actually approached me to correct the problem. With other such issues from other online stores I have had to track down someone to contact for help and then go through an ordeal to obtain assistance. I would use this site again based solely on their proactive service.

Good price, quick shipping, no instant refund though!

cheapest price, better than summitt or jegs too

Lowest price usually means sub-par customer service. Not the case at Autoplicity. I had questions after my item shipped, they responded promptly and professionally multiple times, and were totally willing to work with me. Very satisfying, would not hesitate to order from Autoplicity again.
