Here is all you’ll need to handle the two different-size spanner nuts you’ll find
when servicing the NV4500. As usual, we have not compromised a thing; you can tell
the first time you pick it up! Weighing in at about 24oz, our heavy-duty dual spanner
wrench arrives ready and able.
Design includes a provision for a ½” drive breaker-bar for removal and a torque wrench to install.
We then devised a unique socket for GM’s 4X4 app:
Many use a vibration dampener that will not allow the wrench to access the nut. With
the torque specs this high it absolutely must be burly to stand up to repeated use.
The 4-notch design spreads out the load while maintaining stability. Milled from
super toughsteel, this will be in your tool box for many years!
The T-4500 is designed with “pass-through” capability. Why “pass-through” capability,
you ask? As an intended bonus, the hollow socket allows clearance for the output
shaft enabling this combo to handle the 2wd & 4wd Allison 1000/2000 series!

Many GM 4X4’s use a vibration dampener, (mainly diesels) requiring the use of a hollow socket to reach in to access the nut.
