Eliminate gyroscopic imbalance and belt whipping found in many 3" drives with a BDL drive kit that puts the inner hub a full inch further inboard than most other belt drives. With the rear pulley further over the main shaft virtually all instability in the primary drive is eliminated. The 8mm pulleys are hard anodized and use a special belt that traps less air than HTD belts. The rear pulley has a double row bearing that supports a Stressproof steel clutch hub. Also included are a clutch and polished aluminum pressure plate. Safety guards are always recommended with 3" drive systems.
