True Roller Timing Set - BBM Adjustable

The True Roller Timing Set - BBM Adjustable by CLOYES delivers the precision timing control that serious engine builders and high-performance enthusiasts demand. Whether you're dialing in a stroker motor, tuning a vintage big-block for peak power delivery, or restoring a classic engine to factory specifications, this adjustable timing set ensures your crankshaft and camshaft stay in perfect synchronization across the entire RPM band. CLOYES has engineered this roller-based system to handle the demands of modified engines where stock fixed timing simply cannot adapt to aggressive cam timing or variable load conditions.

True roller timing sets replace the factory cam chain or gear drive with sealed roller components that reduce friction, wear, and deflection—critical advantages in engines running higher valve spring pressures or extended duty cycles. The BBM-series adjustable design allows fine-tuning of cam timing relative to the crank, giving you the flexibility to optimize power delivery, fuel economy, or emissions compliance depending on your combination. Roller technology inherently runs cooler and quieter than traditional timing chains, while the adjustable mechanism lets you compensate for engine modifications without sacrificing reliability or requiring custom cam timing components.

This timing set is ideal for engine builders working on big-block and medium-displacement motors where adjustability extends component life and maximizes horsepower gains from cam upgrades. Installation requires removing the timing cover and front accessory drive—a straightforward procedure for any mechanic with basic engine experience. Verify your engine's bore, displacement, and cam profile compatibility before ordering; the True Roller Timing Set - BBM Adjustable works with most conventional pushrod V8 architectures but requires specific fitment confirmation for your particular application.
