  • For Retro-Fit (Link Bar) Hydraulic Roller Lifters; Fits '58-'021 262-400 cid Chevy Small Blocks2

  • Good mid-range power • Needs headers, 3.55-4.10 gears, 2000+ stall • Noticeable idle

  • Xtreme 4X4™ -Due to the allowances of lower engine speed, these designs are slightly more aggressive than the original Xtreme Energy™ Hydraulic Rollers. Great low & mid-range torque. They are one of our most aggressive hydraulic roller lobes and run well in street, off-road & four-wheeling.

  • Warning: Camshaft Optimized for use with a Melanized or Nitrided distributor gear. Not compatible with cast or steel gears without similar surface treatments. Failure to utilize the proper distributor gear will void all warranties and/or return policies.


1: Cams for '55-'57 engines can be custom ordered. Please Call, Email, Twitter or Live Chat for details.

2: The '87+ Chevy Small Block received provisions for roller lifters. Most '87 - '93 GM cars came with roller lifters, but most '87 - '95 trucks came with flat tappet lifters in roller lifter style blocks. If your block has '87+ OEM-style roller cam provisions but does not have roller components fitted, COMP Hyd. Roller Lifter Install Kit for '87-'90 Blocks or '91-'02 Blocks can be purchased. As well as a '87+ OE-Style COMP Hyd. Roller Cam and '87+ OE-Style COMP Roller Lifters. Pre-'87 blocks require Retro-Fit Link Bar Roller Lifters.
