Description

Designed to exceed OEM specifications, this set provides a 3.73 gear ratio and features 24 splines for a precise fit and reliable performance. Each USA Standard Gear set is subjected to rigorous in-house quality evaluation, ensuring it passes all dimensional, material, and fitment testing before it reaches the customer. This commitment to quality guarantees a product that is built to last and perform under demanding conditions. This ring and pinion set is compatible with the 2007-2017 Jeep Wrangler models equipped with a Dana 30 front differential and 4WD. The reverse rotation design is crucial for specific front differential applications. Ensure your vehicle's specifications match these requirements for proper installation and function.
