Upgrade your drivetrain with Brock’s Heavy Duty Cush Drive Set, made from premium polyurethane compound for long-lasting performance. These units are built to outperform and outlast OEM rubber, providing tighter engagement and reducing drivetrain slack.

Key Features:

• Durable polyurethane material engineered for strength and resilience

• Shore 88 hardness – holds shape better than OEM rubber under load

• Reduces drivetrain “lag” and improves reaction time, ideal for drag racing

• Longer lifespan than stock units – perfect for high-horsepower or daily riding

• Maintains integrity over time – no deformation or compression loss

• Made 100% in the USA with premium materials

Why Upgrade?

Stock rubber cushions wear out fast, leading to imprecise power transfer. Brock’s polyurethane alternative stays firm and consistent, giving you sharper throttle response, better launches, and longer service life—whether on the street or the strip.
