***We now offer the Ultra-Guard without additive for Track Mustangs with Torsen differentials***
If your Mustang see more track time than street time We suggest choosing the Ultra-Guard without the "LS" Limited Slip Additive. In Torsen equipped vehicles removing the additive theoretically will improve the Bias properties of the Torsen on track. Ford uses the additive to 'calm down' the Torsen on the street. Torsens typically will pop and bang during low speed turns which is normal and does not affect the life of the unit. On track with improved Bias the differential can offer improved lock up allowing for more power to the wheels on corner exit.
If you still daily drive your Mustang we recommend running the LS Ultra-Guard to maintain 'street manners' If you have a clutch type differential continue to use the "LS" version.
The Kit Comes Complete With:
4 Quarts (3.78 Liters) of BG Products Syncro Shift II Synthetic Gear Oil, 3 Quarts of Ultra Guard LS, Oil 2 Transfer Pumps with Storage Bags, Thread Sealant Tape and Printed Color Instructions.
No additional additives need to be added for proper operation and performance. We designed this kit to be simple for a casual DIY'ers and minimal left over extra oil. You can even use the container to return your used oil to your oil-recycling center.
