Differential Installation Kit

This set is specifically intended as a replacement for Dana Spicer 44 axles found in the TJ Rubicon, featuring a 4.56 ratio, 26 spline pinion, and a thick carrier design compatible with 3.73 and down carriers. It also requires 10 ring gear bolts and has an 8.50" ring gear diameter. These ring and pinion gears are ideal for improving performance in various driving conditions, including towing, hauling equipment, racing, and off-roading. They are particularly beneficial for restoring acceleration lost due to the addition of oversized tires, allowing your truck to run more efficiently. For towing or racing applications, changing to a higher ratio like 4.56 can allow your engine to put more power to the ground, while also reducing stress on the engine and transmission. Installation of new gears typically requires common hand tools along with a hydraulic press and dial indicator for correct setup. It is also recommended to purchase a master overhaul kit, which includes essential components such as new bearings, seals, shims, and a pinion crush sleeve, to ensure reliable and quiet operation for years to come. USA Standard Gear backs their ring and pinion sets with a one-year warranty against manufacturer defects.
