Tech Note 1: QU10013 Specs
QU10013 is a 4x2 31 spline mainshaft with a full-length 5th gear spline. QU10013 is grooved behind the 5th gear splines for an included, 1/8" wide, 3 piece Thrust Washer Set.
QU10013 Specifications  and Approximate Dimensions:
Overall Length: 24-1/2"
Output Spline: 1.61" x 31
3-4 Synchro Hub Spline: 1.45" x 28
1-2 Synchro Hub Spline: 3.365" x 20
Reverse Clutch Spline: 2.285" x 45
Fifth Gear Spline: 1.79" diameter x 1-7/8" long by 35 spline
Width of 3 Piece Thrust Washer: 1/8"

Tech Note 2: Not a Press Fit
There is currently no available NV4500 mainshaft from any supplier that will have a press fit for the 3-4 synchro, mainshaft 5th gear, or the rear output bearing. They are specifically designed and machined this way to speed assembly. The only shafts that had a press fit were the original equipment New Venture shafts and our Torque King shafts, both of which are long out of production and no longer available.

Tech Note 3: Tech Articles
For more information about NV4500 5th gear failures, see:
5th Gear Failures and Solutions
NV4500 Cast Iron Tailshaft Housings

We no longer make the Torque King® Mainshaft and Retrofit Kits as described in the 5th Gear Failures and Solutions article which leaves full spline shafts the only choice currently available for Dodge NV4500HD transmissions. While full spline shafts do not actually cure the 5th gear issue, they do greatly reduce the chances of the nut backing off.

Tech Note 4: Cummins Diesel
Ever since the Cummins Diesel was introduced in the 1989 Dodge Ram, people have been modifying the engines to crank out more horsepower. Unfortunately, all the manual transmissions used behind the Cummins Diesel (Getrag G360 (1989-1993), NV4500HD (1994-2004), NV5600 (1999-2005), and G56 (2005 to current) are only rated for around stock engine torque. When you increase your power output, you also increase the chance of having a major transmission failure. While some reasonably effective steps can be taken to increase the torque ratings of specific components, there is no practical way I know of to really make your Ram manual transmission "bulletproof" for big torque increases. 

There are claims that cryogenically treating NV4500 gears will increase gear strength as much as 30%. Unfortunately, there does not seem to be any peer-reviewed documentary evidence to support those claims. Cryogenically treating gears is primarily a cold-hardening process that changes the molecular structure of steel to decrease wear while retaining or increasing hardness. If properly done, it is probable the cryogenic treatment process does slightly increase the impact and fatigue resistance of NV4500 gears, but not enough to significantly increase the ability of an NV4500 transmission to reliably handle more than 600 Lb.-Ft. of input torque especially considering the maximum factory torque rating of the NV4500HD transmission is only 460 Lb.-Ft..
