If you are looking for a high RPM hydraulic lifter set for your LS or LT engine, HPR has just the ticket with these GM COPO lifters.
This lifter set was designed for the COPO Series Camaro's that needed 7500+ RPM range that the normal LS7 or "Caddy racing" lifters just could not do. These have special internals that allow for a "slow bleed down" during use so they do not collapse and falter at higher RPM's.
Notable features include:
Drop in installation using factory lifter buckets
High flow disc style check valve for high RPM stablity
Forged steel body and internal piston
Needle roller bearings used on axle wheels
High chromium steel axle for wear resistance
Quiet operation
Single Lifter
