Reduced Travel OE-Style Hydraulic Roller Lifter for '87+ SBC, LT/LS and V6
SB Chevy and Gen III/LS1/LS2/LS6 Type 'R' Pro Magnum Hydraulic Roller Lifter -Individual
Pro Magnum Hydraulic Roller Lifters Chevrolet Small block. For use in blocks originally equipped with hydraulic Roller cam. 1987 to present, and Gen III, LS1, LS2, and LS6. COMP Cams Pro Magnum Hydraulic Roller Lifters are specifically designed to perform at higher engine speeds. When engines are equipped with a hydraulic Camshaft, high rpm is limited by the improper position of the internal piston as the lifter inevitably "pumps up". This improper location results in open valves and therefore leads to lost power or sometimes even engine failure. NOTE: These lifters require an adjustable valve train and must be pre-loaded to .002" to .004" for proper operation!
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 Short 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. And COMP Cams now offers an XD version of these lifters that feature a a billet pushrod seat for added strength and durability in Xtreme Duty applications such as turbo drag cars and offshore powerboats.
