Get Better Traction for the Street

Better Gears in Three Versions

Motive Gear ring and pinion sets are made from high-quality materials using a state-of-the art manufacturing process to deliver unmatched reliability. Motive Gear even gives you a choice—Standard gear sets for daily drivers; trucks, and mild off-roading; Performance gear sets for street machines and race cars; and Performance Pro gear sets for serious racing.

That makes it ideal for street use, even in rain and snow where applying just the right amount of traction is critical.
