GM LSX Hydraulic Roller Lifters - Short Travel

The COMP Cams GM LSX Hydraulic Roller Lifters – Short Travel (part number 15956-16) are a retrofit hydraulic roller lifter set designed specifically for GM LS-series engines. This 16-piece set features a 0.842-inch outside diameter with a link-bar design and short-travel geometry, making them an excellent choice for LS engine builders looking to upgrade from flat-tappet or worn lifter systems without extensive engine block modifications.

Hydraulic roller lifters eliminate the need for valve lash adjustment and automatically compensate for wear, ensuring consistent valve timing across the engine's operating range. The short-travel design reduces preload on the pushrod, resulting in lower valve spring pressures and reduced component stress compared to conventional full-travel lifters. COMP Cams' manufacturing tolerances guarantee proper fitment in stock and late-model LS blocks, with link-bar geometry that maintains stability under high-RPM operation typical of street performance and mild racing applications.

LS engine enthusiasts often choose retrofit hydraulic roller lifters when restoring or modifying engines that originally shipped with flat-tappet designs or when replacing lifters in higher-mileage cores. This set is well-suited for naturally aspirated LS applications, including 5.3L, 5.7L, 6.0L, and 6.2L variants, providing a reliable solution for performance upgrades.
