Double Row Chain 3/8

The Double Row Chain 3/8 from Bert is a precision chain designed for use in second-generation Bert SG transmissions, commonly found in high-performance street and drag racing applications. This component is essential for builders and mechanics who are upgrading or rebuilding Bert transmissions, where chain synchronization is crucial for optimal shift quality and power transfer consistency.

The double-row roller design of this chain offers superior engagement and load distribution compared to single-row alternatives, effectively reducing wear on sprocket teeth and minimizing slack during acceleration and deceleration. With a standard 3/8-inch pitch specification, this chain ensures proper meshing with the internal gear train of Bert SG transmissions, maintaining the efficiency standards required for both street and competition powerplants.

Mechanics and engine builders working on Bert SG transmissions—whether in circle-track, drag, street rod, or road-course applications—will find this chain critical for proper transmission assembly. It is ideal for transmission rebuilds, engine swaps, and performance upgrades, ensuring that original or worn chains are replaced to restore factory shift feel and reliability.
