BBM Billet Roller Timing Set w/Torr. Bearing

The BBM Billet Roller Timing Set w/Torr. Bearing is engineered for serious engine builders and restorers working with classic Mopar B and RB-series powerplants. This precision timing chain assembly replaces worn or failed OEM timing systems, delivering reliable crankshaft-to-camshaft synchronization critical for proper ignition timing, valve lift, and overall engine performance. Built for durability and accuracy, this set addresses the weak points of stock timing chains that stretch or wear over decades of use.

Constructed from billet steel for superior strength and longevity, the BBM Billet Roller Timing Set features double roller chain design—a key advancement over single-roller systems that reduces friction and promotes smoother power transmission. The red series designation indicates Rollmaster-Romac's performance-grade specification, with a torque-limiting bearing that protects against chain tension overload during cold starts or aggressive acceleration. The three-bolt mounting platform and keyway-adjustable design allow precise timing curve optimization, enabling tuners to advance or retard cam timing for peak power delivery across your RPM band without requiring complete reassembly.

This timing set is ideal for engine builders upgrading muscle cars, street rods, and vintage Mopar restorations where reliable ignition timing is non-negotiable. Weighing 3.95 lbs and compact at 6.9 x 10.2 inches, installation fits within standard B and RB-series engine bays. Proper installation requires setting chain tension to manufacturer specifications and verifying cam timing with a degree wheel before final assembly—critical steps that ensure the torque-limiting bearing functions correctly and the roller chain maintains optimal contact with sprockets throughout the entire operating range.
