Anyone running truetracs front and rear? How are they on icey roads?
Grenaded the 3.73 ring and pinion in my front dana 60. Also damaged the spider gears in the open diff. I suspect that when the gears grenaded, the spiders in the open diff bound up with metal debris. Fun fun!
Anyhow, regearing to 4.11 and installing truectracs front and rear on a 2002 7.3 powerstroke f-350. Not a fan of that clutch style rear limited slip. Also, 9000 lbs empty, truck is WAY too heavy for 3.73's.
At 60 mph boost just strarts coming on at 1600 rpms, 3.73 with 33" tires. When towing heavy, really need to be at 1800-2000 rpms, at 60 mph. 2000 rpms is peak torque and better boost (less exuahst gas temps too).
Knock out 2 birds with one stone: lower gearing and some real fkn traction.
