Superior Ring and Pinion Gears


Wrangler YJ 1987-1995


If your Wrangler YJ's tires are larger than stock, you have probably noticed a loss of performance. Regain it, and more with these performance gears from Superior Axle and Gear. The Wrangler YJ came standard with a Model 30 front axle and a Model 35 rear axle. On newer Wrangler YJs, 3.07:1 ratios were "standard" with other options available. When changing from lower ratios, it is often necessary to change the case. If you are unsure of your current ratio, check with your dealership or give our knowledgeable sales staff a call. Have your VIN number handy.

On a four wheel drive vehicle, front and rear 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 changes.
