Hex-A-Just True Roller Timing Set - SBC LS1

The Hex-A-Adjust True Roller Timing Set for SBC LS1 is a precision component built for engine builders and performance enthusiasts seeking reliable, repeatable cam timing control on small-block Chevrolet and LS1 platforms. Modern timing sets must balance durability with adjustability, especially when running aggressive cam profiles or building motors for street and strip duty. This roller-style timing set addresses that need by combining accurate tooth engagement with the ability to fine-tune camshaft phasing without breaking the bank or requiring extensive modification work.

CLOYES engineered this timing set with true roller design, which reduces friction and wear compared to traditional chain-and-sprocket setups while maintaining consistent valve timing across RPM ranges. The hex-adjustment feature allows tuners to dial in precise camshaft phasing—critical for optimizing overlap, managing exhaust scavenging, and maximizing power delivery across the RPM band. Roller chains distribute loads more evenly across sprocket teeth, extending component life under high-RPM and high-boost applications. The compact footprint (7.6 × 1.8 × 7.6 inches) fits within factory timing covers, and the 4.11 lb weight reflects the robust construction necessary for durability.

Engine builders, performance shops, and DIY enthusiasts working on LS1 swaps or small-block Chevrolet stroker builds will benefit most from this timing set's adjustability and reliability. Whether you're tuning a stock replacement or maximizing output on a modified platform, the ability to adjust cam timing without specialty tools or machine work saves hours and delivers repeatable results. Installation is straightforward for anyone familiar with timing set replacement, and the roller design pairs well with modern camshaft profiles and computer-controlled ignition systems.
