## Overview

Lubegard 42851 Universal Limited Slip Supplement is a 4 fl. oz. advanced additive designed to eliminate differential chatter, reduce operating temperatures, and extend the life of clutch packs in limited slip differentials. Compatible with all major vehicle brands, it features patented synthetic LXE technology for superior friction modification and includes rust and corrosion inhibitors to protect internal components, ensuring smoother, quieter, and cooler differential performance.

## Description

LUBEGARD limited slip supplement is a universal limited slip supplement that eliminates differential chatter, reduces temperatures, extends clutch pack and equipment life in any limited slip differential. It also reduces differential temperatures and extends clutch pack and equipment life. It is specifically formulated for the clutches in limited slip differentials. They depend on the operation of pre-loaded clutch packs on each axle shaft. Gear oils made for standard differentials do not contain the additives that make these clutches work. The LUBEGARD limited slip supplement contains patented and synthetic lxe (liquid wax Ester) technology, an advanced friction modifier to eliminate chatter. It contains rust and corrosion inhibitors to protect bearings and gear surfaces. The lxe technology also acts as an enhanced heat transfer component to pull heat out of the gear box and clutches more quickly providing cooler running units. The LUBEGARD limited slip supplement benefits All makes of vehicles with limited slip differentials including GM, Ford and Chrysler. Directions for use: if necessary, remove enough gear oil to maintain a proper level with the addition of LUBEGARD limited slip supplement. Holding tip closed, cut off tip end, add entire contents of the LUBEGARD tube (4 fl. oz. ) into the clutch type limited slip differential. A 4 oz. Tube will treat a standard 2 qtr. system. For larger capacities, follow a treat rate of 2 oz. of LUBEGARD for every quart of differential fluid. For use with synthetic gear and differential oils a double treat rate of 4 oz. per quart will provide the most optimum results. Allow 20 miles of road operation for complete mixing.

## Questions & Answers

**Q: Will this work in a 04 BMW 330i diff ?**
A: The Lubegard 31904 is for Ford products.  I recommend calling the BMW dealer and ask them which type lube and additive are required for your year make and model vehicle.  If you have a rear noise the Lubegard 31904 will not fix the problem, the issue may be a bearing, spacer or something more serious that will require a trained BMW repair mechanic.

**Q: How much do you use for a dana 35 in a jeep cherokee?**
A: One 4 ounce tube treats capacities up to 2 quarts.  Capacities over 2 quarts require a second 4 ounce tube.

**Q: Can I pour all 4oz into a transfer case which has 1 quart of fluid?**
A: I’ve always used it in a rear diff that has a clutch pack for limited slip. You might want to check your owners manual to make sure they require it in the transfer case.

**Q: Would this be a replacement for the mopar limited slip additive?**
A: It works very well in TRD (Toyota) limited slip units which can be very finicky about additives. I don't know what Mopar specs are, or your application requirements.
