Product Details

The COMP Cams SK21-228-4 Xtreme Energy camshaft kit is a complete hydraulic flat tappet performance package designed specifically for Chrysler 383-440 cubic inch big block engines. This Xtreme Energy cam features aggressive lift specifications of .477"/.480" and duration of 241°/247° (advertised), delivering a noticeable increase in mid-range to upper RPM power while maintaining good street manners and vacuum for power brakes.

Complete SK-Kit Includes:

  • High-performance hydraulic flat tappet camshaft with Xtreme Energy lobe profile
  • Matching hydraulic lifter set (16 lifters)
  • Performance 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 except pushrods, which should be checked for proper length after installation. The Xtreme Energy profile is ideal for street/strip applications with modified cylinder heads, intake manifolds, and headers, typically operating in the 1,500-6,000 RPM range. The hydraulic flat tappet design offers performance gains without the maintenance requirements of solid lifter cams.

Great price, great service, A+

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

Autoplicity had the best price on the item i wanted and also has a large selection to choose from. And they also responded quickly to a question that i had asked

great price and customer service

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.

Best price on the internet for my parts. Shipped out the next morning.

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!

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.
