COMP ROLLER LIFTERS 15850-16
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.

• Designed to perform at higher engine speeds
• When equipped with hydraulic lifters, high rpm is limited by improper position of lifter’s internal piston as lifter “pumps up”
• Improper location results in open valves that lead to lost power and possibly engine failure
• Minimize internal piston movement to allow higher engine rpm
