Description

GM part number 88958689 is a high-performance hydraulic roller lifter kit designed by GM Racing and GM Powertrain for aggressive, high-RPM engine builds. Commonly known as the "Cadillac Racing" lifters, they were originally developed for the Cadillac CTS-V racing program.

These lifters are highly sought after by automotive enthusiasts for several specific applications and technical reasons: 

High-RPM Capability: Featuring special reduced-mass internal components, they minimize inertia and prevent lifter "pump-up". This allows Gen III and Gen IV LS engines (such as the LS1, LS2, LS3, LS6, and LS7) to safely rev up to 8,000 RPM. 

Aggressive Camshafts: They provide enhanced valvetrain stability and dynamic control, making them ideal for handling aftermarket, aggressive camshaft profiles and high-load operations.

Engine Platforms: They are a popular upgrade or direct replacement part for various GM V8 applications, including the Chevrolet Corvette, Camaro, and Cadillac CTS-V.

While excellent for street and strip performance, they are optimized for use with single-valve spring applications rather than extreme-pressure dual springs. For best performance and longevity, a lifter preload of 0.050" to 0.100" is recommended during installation
