Olds/Pontiac Hyd. Roller Lifter Set - Retro-Fit

The Olds/Pontiac Hyd. Roller Lifter Set - Retro-Fit by Crower is designed for automotive enthusiasts and professional mechanics looking to upgrade classic Oldsmobile and Pontiac engines to modern hydraulic roller technology. This lifter set is specifically intended to replace worn or stock flat-tappet lifters, allowing for the use of more aggressive cam profiles while ensuring reliable valve train operation.

Hydraulic roller lifters are known for reducing friction and improving durability, which enhances the engine's ability to reach higher RPMs compared to traditional mechanical designs. Crower's hydraulic roller lifters feature precision-engineered roller wheels that track cam lobes with minimal friction and wear, thereby extending the life of both the cam and lifters. The hydraulic design automatically adjusts for valve lash through internal oil pressure, eliminating the need for manual clearance adjustments.

This retrofit lifter set is ideal for builders upgrading Oldsmobile 350, 403, 455, and Pontiac 400, 455 engines, particularly for performance street cars and racing applications. Its lightweight design, weighing 5.45 lbs for the complete set, facilitates straightforward installation without requiring extensive modifications to the engine block. This makes it a valuable choice for those looking to enhance the performance of vintage Olds and Pontiac blocks.
