Product Details

The COMP Cams Xtreme 4x4 hydraulic roller camshaft is specifically engineered for serious off-road and rock crawling applications where low-end torque and throttle response are critical. This camshaft delivers excellent torque production from idle to midrange, making it ideal for 4x4 trucks and SUVs that need maximum grunt at lower RPMs for climbing, towing, and trail performance.

Camshaft Specifications:

  • Advertised Duration: 268°/274° (intake/exhaust)
  • Duration at .050": 230°/234° (intake/exhaust)
  • Valve Lift: .510"/.520" (intake/exhaust) with 1.5:1 rocker ratio
  • Lobe Separation Angle: 110°
  • Hydraulic roller design for reduced friction and increased durability
  • Optimized for small block Chevrolet 262-400 cubic inch engines

Performance Characteristics:

  • Power range: Idle to 5,500 RPM
  • Broad, flat torque curve for excellent drivability
  • Strong vacuum signal maintains power braking and accessories
  • Works with stock or mildly modified cylinder heads
  • Compatible with factory fuel injection or carburetion

This camshaft requires hydraulic roller lifters, compatible valve springs, and pushrods (sold separately). The Xtreme 4x4 grind is designed to work with stock compression ratios and provides excellent low-RPM performance without sacrificing street manners or reliability. Perfect for daily-driven off-road vehicles that need trail-proven torque without compromising on-road civility.

Good

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.

Quick and easy. Hope they have shoes in stock.

Easy order placement, fast shipment
