The Jeep TJ Complete Gear & Install Kit is a complete re-gear package designed for Jeep TJ models equipped with a Dana 30 front axle and AMC Model 35 rear axle. This kit combines front and rear ring & pinion gear sets with master overhaul components, giving you the critical parts needed to complete a full axle ratio change.
This re-gear kit is one of the most popular Jeep TJ gear upgrades for larger tire builds, trail use, and restoring lost power after suspension and tire modifications. It provides significantly better low-speed torque multiplication, improved crawl control, stronger acceleration, and better transmission shift behavior compared to taller factory ratios.
By combining gears and install components into one package, this kit simplifies the re-gearing process and helps ensure compatibility between axle ratios and overhaul parts.

Tech Insight
A 4.56 ratio is commonly recommended for Jeep TJs running 33"35" tires, especially with automatic transmissions or heavier trail setups. It helps restore power lost from oversized tires and improves drivability both on-road and off-road.
Carrier breaks occur when the ring gear mounting position changes between ratio ranges. This means some factory carriers cannot accept deeper gear ratios without replacement.
Proper setup requires accurate pinion depth, backlash, preload, and tooth contact pattern adjustment. Professional installation is strongly recommended.
