BG PRODUCTS COMBO KIT 2015 AND UP MUSTANG - Transmission and Rear Axle Fluid
***REAR AXLE KIT NOW AVAILABLE IN 75W-140*** Please select desired viscosity from the drop down menu.
***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.
This kit combines our MT82 Syncro Shift II Kit with our Ultra Guard LS Rear Axle Kit. This kit saves you money and includes everything you need to service the MT82 6 Speed Manual transmission and the rear axle found in the 2015 and up Ford Mustang.
If you run your Mustang on track you may find the rear axle overheats under certain conditions. Due to requests from our track customers we now offer an option of either the 75W-90 or 75W-140 Ultra Guard LS Lube. With the higher viscosity 75W-140 in road course conditions this oil may in some instances eliminate or delay the Rear Axle Temperature warning in 2016+ Models. As the oil heats up the viscosity improvers in the additive package raise the viscosity of the oil. This helps eliminate the shearing effects caused by the ring and pinion which causes to oil to overheat. The 75W-140 with it's "thicker" properties maintains a better layer of protection under extreme conditions.
