HD Timing Chain

The HD Timing Chain by Brian Tooley Racing is a precision-engineered replacement chain designed for builders and performance enthusiasts who require reliability under high-RPM stress. This heavy-duty chain is particularly beneficial for those working on stroker builds and heavily modified engines, where factory timing chains may stretch or wear, leading to timing slip.

Engineered for consistent valve timing stability across the entire powerband, the HD Timing Chain features reinforced links and precision-ground sprocket engagement surfaces. This design helps resist wear and maintain tight tolerances even during extended high-load operation, making it a reliable choice for performance applications.

Ideal for engine builders upgrading from OEM timing sets or restoring worn chains in high-mileage performance builds, this chain is compatible with specific BTR cam timing components and performance valvetrain systems. Its compact profile and lightweight design are critical for tuning peak horsepower and engine response, making it a valuable addition to any performance engine build.
