Product Details

The COMP Cams SK12-416-8 Xtreme Marine camshaft kit is a complete hydraulic roller cam package designed specifically for Chevrolet small block engines in marine applications. This performance camshaft delivers 212 degrees of intake duration and 218 degrees of exhaust duration, providing improved throttle response and power across the RPM range while maintaining the reliability required for marine environments.

Complete SK-Kit Includes:

  • Xtreme Marine hydraulic roller camshaft with 212/218 duration specs
  • Hydraulic roller lifters designed for marine duty
  • Timing chain set for precise valve timing
  • Assembly lube for proper break-in
  • COMP Cams decals
  • Detailed installation instructions

This camshaft kit is engineered to withstand the demanding conditions of marine use, including extended periods at constant RPM and exposure to moisture. The hydraulic roller design reduces friction and wear compared to flat tappet cams while eliminating the need for break-in procedures. The Xtreme Marine series is specifically calibrated for marine engine applications where reliability and consistent performance are critical.

Fast shipping, great product. Nothing more needs to be said.

great price and customer service

Great site for just about anything Automotive unbeatable prices, lightening fast turnaround, what more could you ask for?

They had the parts I needed at the best price. I needed some questions answered to make sure I was ordering the right parts for a 4 year old car and they were very helpful when I called.

Finding my parts on this website was incredibly easy. The prices were the lowest around and I was kept up to date about the estimated delivery date. Order #19058

Ordered a Trac-Bar from Autoplicity, and didn't have any problems. WILL be back!

Easy ordering and when i did have a question they answered right away! best price on the product too!
