Description
Superior Performance. When upgrading your Jeep Wrangler JK Rubicon with a set of larger wheels and tires, do yourself a favor by installing a set of Mammoth 4x4 5.13 Front & Rear Gears before tackling any rugged off-road 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.

2014 Wrangler - 1567221754order
complain order 15-67221754 dispatch error
Hello, I need your help, since I have a problem with the bad delivery of the order I made on February 6. The parts that arrived are not the ones I ordered 15-67221754. I ordered a set of pinions and wheels with final relationship 4.56 brand Mammoth Front / Rear Ring and Pinion Gear Kit w / Master Overhaul Kit - 4.56 Gears (07-18 Jeep Wrangler JK) and I got others Yukon brand where the front ring and pinion final relationship of 4.56 and the rear ring and pinion 4.88 I have now lost 12 days, since the parts were exported to Ecuador and I have them sent back to California. No one in your telephone line can solve the problem of this inconvenience. For me there are strong expenses for shipping to Ecuador and now return this to the United States again. I hope someone in your company can address this problem and help me find a solution. Francisco 593992350846

2007 Rubicon - EricS
Just right for 35s
The single best upgrade to date if you have the 3.8 engine you will love it. It actually makes 4 high usable off road. The product was a great value and everything in the kit to do the job correctly except lube.
