Product Details

The COMP Cams K11-231-3 Xtreme 4x4 K-Kit is a complete camshaft package designed for Chevrolet Big Block 396-454 engines seeking increased performance for street and off-road applications. This hydraulic flat tappet cam features 210/218 duration specs that deliver a noticeable boost in mid-range torque and horsepower while maintaining good vacuum for power accessories and automatic transmissions.

Complete K-Kit Includes:

  • Xtreme 4x4 hydraulic flat tappet camshaft with 210/218 duration
  • Hydraulic lifters matched to cam profile
  • High-performance valve springs designed for cam lift and rpm range
  • Steel retainers and valve locks
  • Valve stem seals for positive oil control
  • Timing chain set for precise valve timing
  • Assembly lube for proper break-in protection
  • Installation instructions and COMP Cams decals

This kit provides everything needed for a professional camshaft installation in one package, eliminating the guesswork of component matching. The Xtreme 4x4 grind is ideal for 4x4 trucks, tow vehicles, and street machines where low-end torque and throttle response are priorities. Compatible with stock torque converters and rear gear ratios, making it an excellent upgrade that doesn't require extensive drivetrain modifications.
