True Roller Timing Set - GM LS7

The True Roller Timing Set - GM LS7 from CLOYES is a precision-engineered race timing chain kit designed for serious LS engine builders and high-performance enthusiasts. This single roller configuration delivers the reliability and accuracy needed in extreme-duty applications where OEM timing components fall short. The adjustable 3-keyway design allows fine-tuning of ignition timing without requiring expensive aftermarket ECU tuning, making it an essential upgrade for naturally aspirated and forced-induction LS7 platforms.

Built from hardened steel with a true roller chain design, this timing set eliminates the wear and stretch issues common to stamped-steel alternatives. The roller design reduces friction and heat generation across the cam and crankshaft sprockets, translating to improved durability under sustained high-RPM operation. The included thrust bearing maintains precise sprocket alignment and prevents axial load damage, while the adjustable keyway system provides up to 4 degrees of timing correction in either direction—critical for optimizing power delivery and fuel efficiency in modified engines.

This kit is ideal for LS7 engine swaps, race engine builds, and any application where valve timing precision and durability are non-negotiable. Whether you're running a carbureted small-block conversion or a turbocharged crate engine, the True Roller Timing Set maintains synchronization under extreme loads. Installation fits standard GM LS-series engines with LS7 specifications; comprehensive timing verification and proper sprocket alignment are recommended during assembly to maximize performance gains.
