Originally developed for the CTS-V Cadillac Racing program, these lifters were engineered to handle the extreme demands of high-RPM LS engines. Chevrolet Performance designed them with reduced-mass internal components, allowing reliable operation up to 8,000 RPM without the typical issues found in standard hydraulic lifters. Commonly known as “Caddie Race Lifters,” they’ve been proven on GM’s own race engines.
Recommended lifter preload: .050"–.100"
