 The Torque King® Advantage

Our Patented Torque King® Mainshaft is by far the best Mainshaft on the market for both strength and resistance to 5th gear failure.  We are the only supplier that can guarantee NV4500 shafts and gears against the types of fifth gear failures that plague other designs regardless of mileage or age.  No full spline shaft supplier dares provide this type of warranty.  One big difference is our unique shaft design completely supports the 5th gear so it can't rock loose.  Another difference is our shafts are precision machined by top flight manufacturers noted for outstanding quality and high precision machining.  (U.S. Patent No.:  7,210,366)

The grade of steel used in our Dodge 4x4 Gold Series Shafts is of such high quality that the raw material cost alone is greater than the wholesale price of any other NV4500 shaft being sold today, except for the original equipment New Venture Shafts.

We developed the Torque King® design in response to a pattern of  failures experienced by the full spline shaft designs touted by others, including gear loss, spline failure, shaft breakage, spun bearings, and poor fits.  Torque King® shafts are far superior to any other NV4500 shaft design.  Our shafts have stronger steel, more accurate machining, and are of superior design.  No Torque King® fifth gear has ever come off in service.  No Torque King® shaft has ever broken, nor has a spun rear output bearing or any other shaft failure ever been reported.  Since we first introduced our prototypes in 2002, there has been ZERO shaft or nut failures!

Torque King® shafts for NV4500 transmissions are offered in two versions:  

Torque King® SILVER is the original Torque King® design for all NV4500 transmissions.   Featuring a matched shaft with a load bearing support pilot under the gear teeth and double nut set with anti-rotation washer for Dodge or single nut set for GM 4x4 units.  Shaft steel meets or slightly exceeds original equipment specifications.  Shafts Made in U.S.A. except SI Series are imported from Japan. 

Torque King® GOLD Shaft Sets for Dodge feature a matched shaft with a load bearing support pilot under both ends of the gear and either a triple nut set for Dodge 4x4 29 spline applications or double nut set with anti-rotation washer for Dodge 4x2 and 23 spline 4x4 models.  Each Torque King® GOLD Shaft, Gear, and Nut Set is a precision machined, matched set for accurate fit and long life.  Steel used in Dodge 29 spline shafts exceeds original equipment specifications, other applications equal original equipment.  Made in U.S.A.  When long term NV4500 Transmission reliability in rigorous conditions is required, choose the best:  Torque King® GOLD!

Note:  Our Mainshaft and Master Overhaul Kits do not include the  specialized pullers shown in the video.  We have found that most people who can rebuild a transmission have the experience and standard tools needed to successfully remove the old bearings and fifth gear without the special pullers.  However, we do offer these pullers on the NV4500 Tools Page.
