Reduced Travel OE-Style Hydraulic Roller Lifter Set for '87+ SBC and LT/LS

Reduced Travel OE-Style Hydraulic Roller Lifters. When dealing with full travel lifters, certain engines respond better to a light pre-load because it recovers more quickly from any bad harmonics in the valve train. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases stiffness. COMP Cams Reduced Travel Hydraulic Roller Lifters allow you to have the advantages of both light pre-load and reduced oil volume, producing the most stable and highest revving hydraulic lifter available. Applications - Chevy Small Block; All '87+ OEM Roller Blocks; Gen I (L98, TBI 350, Vortec 5.7, Etc), Gen II (LT1, LT4), Gen III and IV (All GM LS Series), or Aftermarket Blocks with OEM-Style Roller Cam Provisions.
