Billet True Roller Tmng Set - GM LS 97-05

The Billet True Roller Timing Set for GM LS 97-05 by CLOYES is purpose-built for LS engine builders and performance enthusiasts who demand reliability under sustained high-RPM operation. Unlike stock stamped-steel timing chains that stretch and wear, this billet true roller timing set replaces the factory chain assembly with precision-engineered components designed to maintain tight valve timing tolerances across the entire RPM band. Whether you're building a street/strip LS1, LS2, or LS6, this kit addresses the critical weak point in stock timing geometry that fails under boost, nitrous, or aggressive cam profiles.

Built from billet steel with true roller design, this timing chain set eliminates the friction and wear characteristics of sleeve-bearing chains while delivering superior load distribution across roller bearing surfaces. The double-roller configuration and 3-keyway adjustable camshaft design (compatible with 0.390-inch raised camshaft applications) allow precise tuning of cam timing without swapping the entire camshaft—a critical advantage for fine-tuning power delivery on forced-induction or high-lift builds. The engineered tooth profile maintains positive engagement and prevents the skip-and-rattle that plagues OEM chains in modified engines, ensuring consistent ignition timing and avoiding destructive belt-to-piston contact.

This timing set is essential for LS-series engine platforms (LS1, LS2, LS6) running over 350 hp or operating with non-stock cam profiles, superchargers, or turbo kits. Installation requires basic timing chain cover removal and is compatible with stock or ported LS cylinder heads, making it suitable for both bolt-on and full-dress engine builds. Weighing 4.15 lbs and packaged in compact dimensions, this kit includes all necessary sprockets and hardware for complete timing drive replacement, eliminating guesswork and ensuring OEM fitment on 1997–2005 GM LS applications.
