Developed for the CTS-V Cadillac Racing program to meet the demands of a high revving RPM engine this is the ultimate LS lifter. The Chevrolet Performance engineers designed special reduced mass internal lifter components to allow the LS engine to accelerate up to 8000RPM's without experiencing problems associated with hydraulic lifters. Also know as "Caddie Race Lifters", these are the proven performers on the GM Race Team engines.
- As developed by GM Racing and GM Powertrain.
- For use in Gen III and Gen IV engines where sustained high rpms are typical.
- Special reduced-mass internal components allow for higher limiting speeds with aggressive camshaft designs.
- Improved valvetrain dynamics and stability will improve horsepower, and high rpms.
- Tested to 8,000 rpm in GM Racing applications.
Gen III and IV LS-Series Engines.
