NV4500 TRANSMISSION REBUILD KITS & SERVICE KITS

Enjoy the satisfaction of a job well done and SAVE $$ by rebuilding/repairing your NV4500 transmission yourself with one or more of our comprehensive QuadKit™ service kits!  Each kit includes the parts, special tools, chemicals, and instructions required to help you complete a specific repair operation on your transmission!  All our top quality rebuild kits are available with or without special tools!

The synchronizer and small parts components supplied in our kits are  genuine New Venture parts.  These parts are more expensive when compared to what everyone else sells, but we have found from bitter experience that saving a few dollars with aftermarket parts does not work out.  In particular, the aftermarket bronze synchronizers many tout as an "improvement" over the high-tech New Venture rings, are in reality a step back to the stiff shifting, light truck transmissions of 40 years ago. Our NV4500 Kits are simply the highest quality and most comprehensive NV4500 rebuild, overhaul, and service kits you can get.

Just need an individual part?  See our NV4500 Parts web page!
For that hard to find small part, see our NV4500 Small Parts web page.


 

MAINSHAFT CHOICES

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 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 ZEROshaft or nut failures! (Yes, we did have one 5th gear come back with broken teeth which led to our discovery of defective cast iron tailshaft housings, see the bottom of this page for more info). 

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.  (Great Pricing on Dodge 4x4 29 spline SI series shafts!)

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!

Torque King® Silver Mainshaft Kit


 

Excerpt From Our

NV4500 Service Manual

Remove any lock or set screws from the mainshaft nut.
 

If your NV4500HD "lost" fifth gear in your Dodge NV4500HD transmission, chances are the gear has worn into the mainshaft.  If you have low mileage transmission and a complete overhaul is not required, you can get back on the road by replacing the mainshaft, fifth gear, and mainshaft nut.  Mainshaft kits for your Dodge 4x4 are available with both Silver and Gold Torque King® Sets.   Order your synchros, bearings, input seal, tools, and small parts as needed.  Tech Article about 5th Gear Failures and the Torque King® Solution!

IMPORTANT NOTE: 

Aftermarket kits are only intended for use in NV4500 transmissions with serviceable mainshafts.  Inspect the 5th gear area of your original mainshaft for wear.  The un-splined area that supports the 5th gear should not be significantly grooved from the old gear.  The new 5th gear should be a press fit.  If you can slide your new 5th gear on the original mainshaft, you should not install this kit as premature failure may occur!  If this is the case with your transmission, you will also need to replace at least the mainshaft and 5th gear. 

If in doubt, CALL US!!!

 NV4500 Mainshaft Nut and 5th Gear Kits  If you had the mainshaft nut back off on your  NV4500 and the mainshaft is still good, you can replace the mainshaft 5th gear without removing the transmission with one of our mainshaft nut and fifth gear kits.  

Torque King® 5th Gear Retrofit Kits for Dodge NV4500HD transmissions behind Cummins Diesel or V-10 gas engines. If just "lost" 5th gear for the 1st time, or your transmission has never had a 5th gear failure, the Retrofit kit may be for you.  A special matched gear, sleeve and double nut set will keep your Dodge rolling without removing the transmission from your truck!  This kit is NOT suitable for high mileage transmissions or ones that had the stock nut and replaced after a failure.  Read the:  Tech Article about 5th Gear Failures and the Torque King® Solution! to see if this kit is right for you.  Kit includes matched gear/sleeve/double nut set, sleeve installer, gear installer, mainshaft nut wrench, splined shaft wrench, two sockets, rear output seal, adhesive and sealant package, and instructions.

Complete Bearing and Seal QuadKits™ are true original equipment replacements with the exact Timken® and Torrington™ bearing numbers as supplied to New Venture.  This is important because 5 of the 8 tapered roller bearing components used in the NV4500 are improved versions of  standard series bearings.  These bearings are identified with unique suffixes.  While standard bearings may dimensionally interchange, they do not meet the strict New Venture design specifications and may not provide satisfactory service life.  Our seals are also exactly as specified by New Venture. Each bearing kit includes ALL the bearings and seals for a particular transmission.  We custom assemble our kits to match your transmission so you don't have to pay for a lot of extra parts as you would from will-fit kits sold elsewhere.   Also includes RTV sealant, and 2 types of Threadlocker.  Note: Dodge 4x2 Tailshaft Bushing sold separately.  Made in U.S.A. although occasionally Timken does supply us with some bearings from their overseas plants.
