About This Product

Got a limited-slip differential that's chattering or grabbing? This Ford Motorsport SVO friction modifier additive can smooth things out.

Brand is Ford Racing, part number OILADD, interchange number CM-19546-A1. Comes brand new in original packaging with a 1-year warranty. Just add the recommended amount to your differential gear oil during a change or top-up. Reduces noise, improves performance, and extends diff life. Don't use it in open diffs or lockers — only clutch-type LSDs. Essential maintenance for performance cars, trucks, or any vehicle with a posi rear end. Keep your diff happy!
