Set of 16 High Performance Bowtie Lifters

Developed for the CTS-V Cadillac Racing program to meet the demands of high revving engines, this is the ultimate factory GM 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 "Caddy Race Lifters", these are proven performers from the GM Race Team engines. The valving in these lifters is optimized for single spring applications, not recommended for higher pressure dual spring combinations.

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 8000 rpm in GM Racing applications

Recommended preload is .050" - .100".
