SB Mopar Gear Drive

The SB Mopar Gear Drive from MILODON is a precision-engineered timing gear system designed for serious small-block Mopar builders who demand reliability over noise. Unlike traditional chain-drive systems, this gear drive eliminates timing chain stretch and slack that accumulate over thousands of miles, ensuring your ignition timing remains consistently accurate under high RPM and boost conditions. Whether you're building a stroker 408, a turbocharged 360, or a race-prepped 340, a quality gear drive is essential insurance against cam timing drift that compromises performance and fuel economy.

MILODON's gear drive uses hardened steel gears and a robust distribution design that maintains exact 1:2 crankshaft-to-camshaft ratio without the wear characteristics of conventional roller chains. The system runs slightly noisier than a chain—a trade-off serious mechanics accept because gear engagement is mechanical law, not dependent on tensioner spring pressure or chain condition. At 6.5 pounds, the complete assembly integrates seamlessly with your existing small-block Mopar block, requiring no machine work beyond standard timing cover removal. The compact 8 x 1.5 x 17.75-inch package fits within factory engine bay constraints while delivering the kind of repeatable, zero-slop timing control that separates a reliable street engine from one prone to detonation issues and performance variability.

This gear drive is ideal for engine builders, hot rodders, and performance enthusiasts who run higher compression ratios, aggressive cam profiles, or forced induction on small-block Mopar platforms. Installation pairs with a standard timing cover and requires basic mechanical competency; no special tools are needed beyond what's already in a shop. For maximum longevity, pair this with quality engine oil and a heat-cycled break-in—the gears need proper lubrication flow to prevent premature wear. Whether your SB Mopar is a street cruiser, strip racer, or weekend warrior, this MILODON gear drive eliminates one variable from the timing equation, letting you focus on tuning fuel, boost, and ignition curve with confidence that your cam timing will stay put.
