Chry Bb&426 Hemi Hi-Tech Roll Tim/Set 60-73 3Bolt

The COMP CAMS Chrysler 426 Hemi Hi-Tech Roll Timing Set for 1960–1973 models is a double-roller timing chain kit engineered for the legendary B-series and RB-series Mopar engines. Built from cast iron and billet steel construction, this timing chain set delivers the precision synchronization critical to high-performance Hemi engine builds where ignition timing accuracy directly impacts horsepower delivery and engine longevity.

The hi-tech double-roller design reduces friction and wear compared to single-roller systems, translating to more efficient power transfer and extended service intervals in demanding applications. The three-bolt mounting configuration ensures compatibility with factory and aftermarket Hemi engine blocks across the 1960–1973 production window. Proper timing chain tension and alignment are non-negotiable for maintaining valve event precision in high-RPM operation—this kit addresses both through engineered durability and validated fitment on countless Mopar restoration and performance projects.

This timing set is suited for Hemi engine rebuilds, restorations, and performance applications where OEM or worn timing chains require replacement. COMP CAMS is recognized for manufacturing timing components to strict tolerances, making this kit a preferred choice for engine builders and restorers who need verified fitment and reliability. The complete kit approach eliminates the guesswork of sourcing individual timing components separately.

Whether refreshing a classic Mopar muscle car or building a period-correct engine assembly, proper timing chain maintenance ensures predictable engine behavior and maximizes the service life of other internal components. This COMP CAMS kit is the engineered foundation that serious Hemi enthusiasts specify for precision and durability.
