【Replacement】Replaces Part# 12499225, HL124, 12680871, 17122490, 12648846 commonly found on popular GM vehicles including year models 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 00, 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15, 16, 17. Overtime, hydraulic roller lifters will wear out resulting in misfiring, inconsistent and lack of engine power, typically during start up.
【How it Works】The valve lifter will effectively fill all the gaps of the valve train, and there is no gap between the roller and the convex shaft, so as to avoid the knocking sound of the hydraulic lifter. This helps to ensure less engine noise and high performance.
【Premium Quality】Made of high quality durable materials and precision CNC machining to meet the requirements of racing lifts and withstand continuous high speed operation.
