Description

The USA Standard Ring & Pinion gear set is engineered for reliable performance in Dana Spicer 30 axles featuring a short pinion design. This set is precisely manufactured with a 7.20-inch ring gear diameter, a 26-spline pinion, and utilizes 10 ring gear bolts for secure mounting. With a 3.73 gear ratio, this set provides a versatile gearing solution. This ratio is often chosen to enhance acceleration and off-road capability without significantly compromising highway cruising RPMs, making it a popular choice for many Jeep TJ models. USA Standard Gear aims to provide confidence in installation with their quality components. This ring and pinion set is backed by a 1-year warranty against manufacturer defects, underscoring the brand's commitment to quality and durability.
