Royal Purple Gear Oil
This 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.
Ford Racing Friction Modifier
Ford Racing friction modifier is a specially formulated additive to provide smooth operation of clutch-type limited-slip differentials. 1 bottle of friction modifier is required when changing the gear oil in rear ends equipped with Ford traction-lock units.

Testimonial: The best company I have ever dealt with
LRS hands down is doing everything right. Every experience I have ever had with them shows just what an amazing company they are. There is a reason I come back time after time, instead of going to those "other" mustang aftermarket websites. Customer service is the name of their game, and they are winning. It does not matter whether you call, email, forum PM, or go to the actual store, they are always incredibly helpful and enthusiastic. (Getting to see the Cobra R in their showroom was awesome). I'm proud to have the LRS windshield banner on my car, because I know they will always have my back.
