DMI Bulldog XR3 8" Ring Gear 4.12 Ratio Thermal Coating, Mag Center- Black

The Bulldog XR-3 utilizes an 8" 4.12 ring and pinion that saves more than 2.5lbs compared to a conventional 10" gear. The XR-3 was developed using the latest computer F.E.A. technology to develop and engineer the rear. The rear is a direct replacement utilizing standard 10 spline quick change gears commonly used in full size rears along with conventional length driveline components. The rear offers an additional 2" of fuel cell clearance and 1.75" of seat clearance. The ring and pinion has been used successfully in applications up to 800 horsepower on both dirt and pavement. This rear is an excellent choice for RaceSaver®, 305 or 360 sprint car competitors. All axles feature 1" increased left side spline length to accomodate deeper offset wheels.
