ARB Lockers
Hi All, I am exploring the possibility of installing an ARB lockers on either the front/rear or both axles. I currently have a limited slip in the rear axle. My ONLY reason to install an ARB ...
Forum Discussion
I called Eaton regarding my current exact set-up.....truck/camper, axle weights and so forth.
The Eaton representative informed me, to my great surprise, that the 2013 RAM with the 11.5" AAM rear axle has a TracRite GT Helical Gear Limited Slip in it. It does not have a clutch pack that could wear out or need special fluid additives like I originally thought.
From their website:
TracRite® GT - Helical Gear Limited Slip Differential
AAM produces a wide variety of differential cases and assemblies for the aftermarket. Each is designed to the exacting specifications of the OEM vehicle manufacture. Each differential assembly is built to OEM specs because they are the same units made for OEM production use. The TracRite® GT is a helical gear designed limited slip style differential. The torque bias is proportional to the throttle, providing a smooth application of torque to the wheels. Since this differential uses helical gears, there are no clutch plates to wear and no friction additives are needed. The TracRite® GT is compatible with ABS, traction and stability control systems. When you want your vehicle to perform like the OEM it is, use the OEM replacement parts made by the original manufacture.
Features:
Before differentiation occurs, gear radial and thrust forces generated by the torque on the gears cause frictional forces in the differential between the gear to gear interfaces and gear to case interfaces
Once the frictional forces are overcome, differentiation will occur
The torque will be continually biased, by the frictional forces, to the high traction wheel
Torque bias ratio is tunable by modifying helical gear geometry
Torque to turn (pre-load) is tunable by adjusting the amount of spring pre-load
Increases traction effort on high mu wheel through the multiplication factor of the TBR. Higher TBR of limited slips increases the amount of torque that can be transferred
Compatible with ABS, traction and stability control systems
Applicable to front or rear axles, and transaxle / transmissions
He said not exactly like their TrueTrac, but recommended that I leave it there and just keep the oil changed per spec. He stated that they do not make an application for the AAM 9.25" front axle but that what I have in the front along with the factory TracRite is plenty enough for my projected applications.
That bit if news saved me some $$$$
