LS Hyd Roller Lifter Set Tie-Bar Design

The MOREL LIFTERS LS Hyd Roller Lifter Set Tie-Bar Design (part number 5290) is a 16-piece hydraulic roller lifter set designed for GM LS-series engines. This set is ideal for street performance applications, providing enhanced reliability and performance over original hydraulic flat tappets.

Featuring a tie-bar design, these hydraulic roller lifters maintain precise valve timing and reduce valve train noise. The lifters have an outer diameter of 0.842 inches, which is consistent with LS-series specifications, ensuring compatibility with many LS engine builds. The internal oil passages allow for automatic compensation for valve train wear and thermal expansion, eliminating the need for manual lash adjustments.

This lifter set is particularly beneficial for LS engine builders looking to upgrade their stock engines or assemble high-performance stroker combinations. The tie-bar configuration locks the lifters together, preventing misalignment during high-rpm operation, making it suitable for street-driven vehicles and moderate boost applications.
