Tired of that annoying chatter from your differential? Lubegard's Limited Slip Supplement is here to save the day! This 4oz bottle works like magic in any limited slip differential - whether you drive a GM, Ford, Chrysler, or anything else. It completely eliminates that awful differential chatter, squeals, and groans that make your car sound like it's falling apart. The secret is their patented synthetic lxe technology that not only stops the noise but also reduces temperatures and extends the life of your clutch packs. Super easy to use - just remove a little gear oil if needed, cut the tip, and pour the whole tube into your differential. For standard 2-quart systems, one tube does the trick. If you're running synthetic gear oil, double up for best results. Give it about 20 miles of driving to fully mix and work its magic. Plus it's got rust and corrosion inhibitors to protect your bearings and gear surfaces. Seriously, this stuff is a must-have if you want your differential running smooth and quiet for years to come.
