Nitro Gear & Axle strives to develop new applications & ratios, as well as improve upon existing applications. As many of you installers may know, the 9.25” Chrysler rear axle is fairly failure prone, and many of the aftermarket ring & pinions are often noisy. Nitro now offers OEM quality Ring & Pinions in 3.55 3.92 & 4.10 ratios. The high cost of OEM Chrysler gears and the questionable quality of other aftermarket gears make the new Nitro premium ring & pinion an excellent choice.
Computer controlled machining, heat treating and lapping processes ensure a strong, quieter running and installer-friendly Ring & Pinion.
