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.

  • 2020 Mercedes GLS450
Size: 4 fluid ounces Style: Bottle
Mercedes 2020 GLS 450 / Transfer Case: Recently didn't routine maintenance on our GLS with 95k miles. Last time was at 50k miles. Front/Rear differentials and transfer case. I was getting the low speed humming on turns after the service. I used MB fluids that were called for from the dealership. The transfer case is Limited Slip, but the differentials are not. I ultimately decided to try this product (I use their HVAC cleaner, and also trans additive in my Ford 10R60). Within 10 miles, the noise and corresponding vibration was completely gone. One bottle into the transfer case with the fresh MB 239.41 gear oil, and it's back to behaving like the day I bought it. Sharing because I don't see any Mercedes reviews. ... show more

  • This stuff is awesome!
Size: 4 fluid ounces Style: Bottle
This was magic for my transmission. I had a bad shutter. My mechanic told me to try this for my torque converter prior to replacing it. If I had not seen this, I would not have believed it! This stuff is unbelievable! I know it's probably only a patch but it has bought me more time.
