This is a complete set of hydraulic roller lifters for 1987–1995 GM engines. These lifters are precision-engineered to maintain quiet valvetrain operation and consistent valve timing. Designed for engines originally equipped with a factory roller camshaft, these lifters feature an internal valving system that resists varnish buildup and ensures reliable oil pressure.

Item is in good used condition. Each lifter has been thoroughly inspected for smooth plunger movement and free rotation of the roller wheel. There is no pitting, flat-spotting, or scoring on the roller surfaces. As a used engine component, please expect minor oil staining. It is highly recommended to soak these lifters in clean engine oil for 24 hours prior to installation to ensure they are fully primed.

PLEASE NOTE: Internal engine work requires advanced mechanical knowledge. For safety and engine longevity, it is strongly recommended that these lifters be installed by a certified professional technician. Failure to properly prime lifters or correctly align them with factory retainers/dog-bones can cause catastrophic engine failure. The seller is not responsible for any damage or engine failure resulting from improper installation.
