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!
