Product Details

The COMP Cams SK11-243-4 Xtreme 4x4 camshaft kit is designed for Chevrolet Big Block 396-454 engines seeking aggressive performance with hydraulic flat tappet convenience. This cam delivers a 234/244 duration split that produces strong mid-range to top-end power, making it ideal for off-road trucks, rock crawlers, and street/strip applications where low-end torque and high-RPM power are both critical.

Complete SK-Kit Includes:

  • Xtreme 4x4 hydraulic flat tappet camshaft with 234/244 advertised duration
  • Matching hydraulic lifter set engineered for this cam profile
  • Timing chain set with gears for precise valve timing
  • Assembly lube to protect critical components during initial break-in
  • Installation instructions and COMP Cams decals

This camshaft features COMP Cams' Xtreme 4x4 grind specifically engineered for high-performance applications demanding broad, usable power across the RPM range. The hydraulic flat tappet design eliminates the need for constant valve adjustments while maintaining durability in demanding conditions. Ideal for engines with aftermarket cylinder heads, intake manifolds, and headers seeking maximum performance without sacrificing street manners.

Application: Chevrolet Big Block 396, 402, 427, and 454 cubic inch V8 engines.

I searched the entire web looking for the best price on my item and found that Autoplicity beat everybody else in price & quality. Search no more!

Autoplicity had the best price on the VP fuel jugs, I ask if the could ship them out quickly and they did.

I ordered a new battery for my Harley. I wanted a battery that would last and be of good quality. I bought a Odyssey PC545 battery it stats stat it will last up to 8 years and is military grade. My package arrived quick and in good shape. My order number is #5600. Thanks

i was skeptical about this site but after reading the reviews and them having the lowest price i could find for my part i pulled the trigger and wasn't disappointed. fast shipping and low prices with great customer service will shop with them again if they have what im looking for.

Smooth easy process
