Product Description

Mustang Yukon 4.11 Gear Kit
Increase acceleration on the street and the track with this Yukon 1986-2009 Mustang 4.11 gear kit! Rear end gears are the best way to get a "seat of the pants" increase in performance on your Mustang. Once installed, you can instantly feel the difference unlike most other modifications! Yukon gears feature a heavy duty construction that's built to last! Each gear is precision machined for a smooth and quiet operation for years to come. Yukon backs this gear kit against manufacturer's defects for one year. This kit includes everything needed to install 4.11 gears on your Mustang!

Gear Installation Kit
The M-4210-B2 gear install kit from Ford Performance includes everything you need for a ring and pinion gear swap on a Mustang 8.8" rear axle. This kit includes the same high torque pinion bearing found in the 2012 Mustang GT500. This bearing increases durability for modified Mustangs. Along with the GT500 bearing, this kit includes a carrier and pinion shim set, carrier bearings w/ races, pinion seal, ring gear bolts, crush sleeve, pinion nut, marking compound, and differential cover gasket!

Ford Performance Friction Modifier
Ford Performance friction modifier is a specially formulated additive to provide smooth operation of clutch-type, limited-slip differentials. One bottle of friction modifier is required when changing the gear oil in rear ends equipped with Ford traction-lock units.

Royal Purple Max-Gear Oil
Royal Purple Max-Gear gear oil is an ultra-tough automotive gear oil. It’s designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler and longer without overhauls. Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple’s proprietary Synslide additive technology.

Installation Note
Although the Royal Purple gear oil has friction modifier mixed in, it is still recommended that you use the bottle of Ford Performance friction modifier to supply your 8.8 rear end with the proper amount of modifier.
