BG ULTRA-GUARD 2015-2024 FORD MUSTANG SHELBY GT350 TRACK PACK - MACH 1 REAR AXLE LUBE CHANGE KIT
***Also works with MACH 1 that has additional coolers***
***NOW AVAILABLE IN 75W-140*** Please select desired viscosity from the drop down menu. We recommend 75W-90 for vehicles equipped with the Factory Rear Differential Cooler.
***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'
We are now a stocking dealer for BG Products. We are offering this Complete S550 2015-16 Mustang Shelby GT350 Rear Axle Lube Change Kit. This kit will provide additional protection during track use over the factory oil. The rear axle operates at a higher temperature in the new model, so much so that Ford installed a Rear Axle Temperature Warning in the 2016 Models.
The Factory Fluid is only a 75W-85-viscosity oil which is great for fuel mileage but not so great during a 20 minute on track session where the differential is working overtime to send power to the rear wheels. We offer 75W-90 oil that in cool temperatures acts like the factory oil but during higher temperatures provides slightly improved film strength. The additional oil film strength provides a ‘cushion’, preventing metal-to-metal contact, which helps lower operating temperatures.
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.
The Kit Comes Complete With:
2.8 Liters of BG Products Ultra-Guard® LS Full Synthetic Gear Lubricant, Oil Transfer Pump with Storage Bag, Thread Sealant, Level Checker and Printed Color Instructions.
This is a premium quality product that offers extended protection and is designed for long life at extended operating temperatures. This oil is compatible with all Limited Slip, Traction Lock and Torsen Type Differentials.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.
