      Description

      Superior Performance. When installing bigger tires on your 2007-2018 JK, do yourself a favor by upgrading to a set of Mammoth 4x4 4.56 Front & Rear Gears before hitting the trails. Designed to give you the confidence necessary to take on rough conditions, these high quality Mammoth Gears will put more power to the ground to compensate for oversized tires ensuring traction over rocks and trail hazards. This Mammoth Front & Rear Gear Kit includes top quality bearings, seals, front and rear gears with install kits, and all the accessories needed to install your new ring and pinion set.

      Re-Gearing. When you increase the rolling diameter of your tires, the engine has to work twice as hard to turn them. Naturally, this will lead to an increase in fuel consumption and reduced performance. However, by re-gearing your rig to match your new larger tires, you can regain this lost acceleration, performance and fuel economy.

      Quality Construction. Featuring a premium design and the use of high-tech technology in their manufacturing makes Mammoth 4x4 Ring and Pinion Gears one of the best gears available on the aftermarket today. Mammoth Gear sets are manufactured from the highest quality steel available and are precision heat treated to OEM specifications for extreme durability and a longer life.

      Professional Installation Recommended. The installation of Ring and Pinon Gears can be a very intricate process, so mechanical experience is highly recommended. Follow the included instructions for best results.

      Application. This Mammoth 4.56 Front & Rear Gear Kit with Master Overhaul Kit is designed for use on 2007-2018 Jeep Wrangler JK models. Please select your application from the options available.
