GM LS Hyd. Roller Lifter Set - Tie-Bar Design

The GM LS Hydraulic Roller Lifter Set with Tie-Bar Design from CAM MOTION INC is a complete 16-piece lifter kit engineered for General Motors LS-series engine builds. This set of hydraulic roller lifters features a 0.842-inch outer diameter and reduced-travel design optimized for high-performance and stock-replacement applications in LS1, LS2, LS3, and compatible LS-platform engines.

Hydraulic roller lifters deliver significant advantages over flat-tappet designs: reduced friction, lower wear on cam lobes, and improved valve train stability across a wider RPM range. The tie-bar configuration ensures controlled lifter spread and prevents valvetrain chattering, critical for maintaining precision in boost-sensitive and high-revving LS builds. Reduced-travel design minimizes lifter preload variability, enhancing engine longevity and consistency. At 5.45 lbs for the complete set, installation is straightforward in standard LS engine blocks without requiring custom modifications.

This lifter set suits engine builders and enthusiasts upgrading stock LS engines, rebuilding cores after high-mileage use, or constructing moderate to aggressive naturally aspirated and forced-induction combinations. The 0.842-inch OD is the standard specification for late-model LS applications, ensuring compatibility with factory cam profiles and existing cylinder head preparations. Whether for street performance, track duty, or customer rebuilds, this complete set eliminates sourcing individual lifters and guarantees matched geometry across all sixteen positions.
