Product Details

The COMP Cams K12-243-3 Xtreme 4x4 K-Kit is a complete camshaft installation package designed for Chevrolet small block engines. This hydraulic flat tappet camshaft delivers 226 degrees of intake duration and 234 degrees of exhaust duration, providing excellent mid-range torque and horsepower gains ideal for street/strip and off-road applications.

Complete K-Kit Includes:

  • Xtreme 4x4 hydraulic flat tappet camshaft
  • Hydraulic lifters engineered to match cam profile
  • Performance valve springs for increased valve control
  • Steel retainers and precision valve locks
  • Valve stem seals for proper oil control
  • Timing chain set with gears
  • Assembly lube for proper break-in
  • Installation instructions and COMP Cams decals

This all-in-one kit eliminates the guesswork of component matching, ensuring all valvetrain components are properly engineered to work together. The Xtreme 4x4 grind is specifically designed for trucks, SUVs, and 4x4 vehicles where low-end torque and throttle response are critical. Ideal for engines with stock or mildly modified cylinder heads, this camshaft provides a noticeable performance increase while maintaining good street manners and vacuum for power brakes.

Quick and easy and was able to use my amazon account as well

Ordering was easy and accurate. I received my order in a timely manner and items were as described.

Had the best price on my parts & shipping was cheaper than I expected.

Thank you for the fair price and I hope shipping is quick. If it is, we will buy mufflers from you in bulk. 50 or more at a time.

Great price on a new tonneau cover for my '08 Honda Ridgeline.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.
