SBM Billet Roller Adj. Timing Set

The SBM Billet Roller Adj. Timing Set from ROLLMASTER-ROMAC is a precision-engineered timing chain assembly designed for small block Mopar engines requiring reliable, adjustable valve timing control. Built for engine builders, performance enthusiasts, and restoration specialists, this double roller timing set eliminates the guesswork in camshaft synchronization while delivering the durability demanded by street and competition builds. The adjustable keyway design allows fine-tuning of ignition and valve overlap to optimize engine performance across varying RPM ranges and load conditions.

This timing set features a robust billet steel construction with dual roller chain technology, which reduces friction and wear compared to single-roller designs while maintaining precise sprocket engagement. The needle bearing design minimizes lateral play and ensures smooth, quiet operation under sustained engine load. The keyway adjustment capability enables users to advance or retard cam timing without removing the sprocket, a critical feature for tuning intake and exhaust overlap, improving fuel atomization, and maximizing cylinder scavenging. The Gold Series designation reflects Rollmaster-Romac's commitment to premium materials and manufacturing tolerances that exceed OEM specifications.

This timing kit is ideal for small block Mopar applications where stock timing chains have worn or where engine modifications demand greater control over valve events. Installation requires basic engine disassembly and familiarity with camshaft timing procedures; comprehensive setup documentation ensures proper alignment and keyway positioning. Whether preparing a 340, 360, or other SBM platform for increased displacement, nitrous oxide, or supercharger duty, this adjustable timing set provides the flexibility to dial in optimal performance while eliminating slack and noise inherent in factory timing chains.
