Product Details

The COMP Cams Xtreme 4x4 camshaft is engineered specifically for off-road and rock crawling applications where maximum low-end torque and throttle response are critical. This hydraulic flat tappet camshaft features 210 degrees of intake duration and 218 degrees of exhaust duration at .050" lift, delivering strong torque from idle through the midrange powerband.

Key Features:

  • Designed for Chevrolet Big Block engines (396, 402, 427, 454 cubic inches)
  • 210/218 duration at .050" lift provides excellent low-end torque
  • Hydraulic flat tappet design for reliable street and off-road performance
  • Ideal for 4x4 trucks, rock crawlers, and trail rigs requiring maximum grunt
  • Works with stock valve springs and factory valve train components
  • Broad torque curve optimized for crawling and towing applications

This camshaft is specifically profiled for vehicles that need strong acceleration from a dead stop and sustained pulling power at lower RPMs. The Xtreme 4x4 series is COMP Cams' most popular choice for serious off-road enthusiasts running big block Chevrolet power. Recommended RPM range keeps engine speeds compatible with off-road driving conditions while maximizing traction and control.

Very fast transaction and shipping info.. Best price found on the internet..

Excellent place to deal with. I am a returning customer and love the fast shipping!!

After shopping around for a specific cargo carrier, Autoplicity had the best total price by over $50 and great ratings, so I gave them a try. I received the SportRack Aero XL - A90275 last Thursday and am VERY impressed with their price and service. The cargo carrier arrived quickly (ordered Sat, rec'd Thurs) and in fine shape. I will recommend Autoplicity to my friends, and plan to shop with them for my future automotive needs.

Prices are very good. There was a slight issue with my order, but it was taken care of after being passed around to a few different departments when I called. Would order from them again.

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.

Great price on my short ram air intake... Actually, best I could find on the Internet. Product shipped the day after the order. Haven't had any problems so far, but it was only shipped just today.

Quick and easy ordering experience!

easy to order parts

Great price, fast shipping, excellent customer service. I will definitely do business with them in the future.
