Description

The USA Standard Gear ZG D44JK-456RUB is a replacement Ring & Pinion gear set specifically engineered for the Dana Spicer 44 JK rear axle. This set offers a 4.56 ratio, designed to revive acceleration and improve efficiency, especially when dealing with oversized tires, towing, or racing applications. The gear set features a 24 spline pinion, an 8.89-inch ring gear diameter, and is secured by 10 ring gear bolts. USA Standard Gear prioritizes high performance and quality, with sets designed from state-of-the-art software and manufactured using the latest technologies to ensure durability and ease of installation. All sets are subjected to rigorous in-house quality evaluation to confirm they meet dimensional, material, and fitment standards, aiming to exceed OEM specifications. Installation of new gears in your axle generally requires common hand tools, along with a hydraulic press and dial indicator for correct setup. It is also recommended to use a master overhaul kit, which includes essential components like new bearings, seals, shims, and a pinion crush sleeve, to ensure reliable and quiet operation for years to come. USA Standard Gear backs these ring and pinion sets with a one-year warranty against manufacturer defects.
