SBM Billet Double Roller Timing Set

The SBM Billet Double Roller Timing Set from JP Performance is a precision-engineered timing chain assembly designed for Small Block Mopar engines seeking reliable valve train synchronization and extended component life. Built for builders and enthusiasts who demand tight tolerances and repeatable performance, this double roller chain set eliminates the wear patterns and slop inherent in single roller designs. The adjustable keyway feature allows fine-tuning of ignition timing without requiring complete engine disassembly, making it an ideal choice for both street and competition applications where timing accuracy directly impacts efficiency and power delivery.

Manufactured from billet steel, the SBM Billet Double Roller Timing Set delivers superior strength and dimensional stability compared to cast alternatives. The double roller configuration reduces friction and wear by distributing loading across two rows of sprocket teeth, resulting in smoother chain engagement and extended service intervals. Engineered 0.010 inches shorter than OEM specifications, this kit accommodates modern cam profiles and upgraded cylinder head packages while maintaining proper chain tension. The keyway-adjustable design provides typically ±4 degrees of crankshaft timing adjustment, enabling tuners to optimize combustion timing for specific fuel octane, boost levels, or camshaft phasing characteristics without additional machine work.

This timing set is engineered specifically for Small Block Mopar platforms including 273, 318, 340, and 360 cubic inch variants. Installation requires standard timing cover removal and is compatible with both original and performance aftermarket camshaft packages. The compact footprint (7.05 x 1.5 x 10.3 inches) ensures straightforward fitment in tight engine bay configurations. Weighing 3.77 lbs, the complete kit includes all necessary sprockets and hardware for a clean, factory-appearing installation that delivers measurable improvements in valve timing precision and long-term reliability for street, strip, and road course applications.
