Hex-A-Just True Roller Timing Set - GM LS7

The Cloyes Hex-A-Just True Roller Timing Set for GM LS7 engines delivers precision timing control with adjustable cam timing capability built into a single-roller, steel construction kit. This timing chain set is engineered for LS7-powered applications where precise valve event control and reliability are non-negotiable. The adjustable design allows tuners and engine builders to dial in optimal cam timing for peak performance across different operating conditions without requiring external phasing tools or additional components.

The true roller design reduces friction and wear compared to standard cam chain systems, translating to improved durability and consistent timing accuracy over extended use. Steel construction throughout ensures the kit can handle the high RPMs and aggressive cam profiles common in performance LS7 builds. The Hex-A-Just mechanism integrates directly into the system, eliminating the need for external adjusters while maintaining tight tolerances that keep your cam timing stable under load. This all-in-one kit approach simplifies installation and reduces potential leak points compared to systems requiring separate phasing hardware.

This timing set is purpose-built for LS7 enthusiasts—engine builders, performance shops, and dedicated tuners optimizing fuel delivery, ignition timing, and valve overlap. Whether tuning for street performance, dedicated track duty, or naturally aspirated horsepower, the ability to adjust cam timing without auxiliary equipment provides real flexibility. Cloyes has established market presence in the LS-platform community as a reliable source for timing components that balance innovation with proven durability.

LS7 timing set specifications matter because they directly affect how efficiently your engine breathes and fires. A true roller chain minimizes parasitic drag losses, while adjustable timing lets you compensate for cam lobe characteristics and carbureted or fuel-injected tune-up strategies. For serious LS7 applications, selecting the right timing control system is as important as selecting your cam itself.
