Superior Ring and Pinion Gears


Wrangler JK & Unlimited
2007, 2008, 2009

If your new Wrangler JK's tires are larger than stock, you have probably noticed a loss of performance. Want to regain it, and more? With the correct gear solution from Superior, you can!!! The standard Wrangler JK comes with a 3.21:1 gear ratio. Even with the optional (standard on Rubicon models) 4.10:1 gear ratio is still not optimized for power with larger tires. If you are looking for the most low-end power from your Wrangler JK, choose the 5.13:1 gear ratio with 35" or larger tires or the 4.88:1 gear ratio for 33"-34" tires.

On a four wheel drive vehicle, front and rear gear ratio's MUST be matched!!!

Many replacement parts are required when installing new gears. Superior installation kits are a sure way to have all the highest quality parts you need. Professional installation is required for all gear changes.
