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.

This is by far the best experience I have ever had buying parts for my mustang. There is no other place for me, then LatemodelResto. I have bought multiple parts over multiple orders and have had nothing but a smile from ear to ear. Aaron Westerman was my contact person from LatemodelResto. I could not ask for a better customer service representative than him! He went above and beyond multiple times for me and made my experience with Latemodel the reason I keep coming back. LatemodelResto will continue being my #1 stop for my Mustang parts.
