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!

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.

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.  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.
Complete Bearing and Seal Kits (Specify year and model)

Restore critical mainshaft and countershaft end-play with new genuine Timken® tapered bearings!  These are the exact fit, premium-duty bearings as specified by New Venture/MTM.  We do not substitute cheaper, lower rated wheel bearings as sold by almost everyone else. These Bearing and Seal Kits include input, output, and countershaft bearings with bearing cups plus the correct input and output seals for your application.  Also includes input shaft pilot bearing, input shaft thrust bearing, RTV sealant, and 2 types of Threadlocker. Made in U.S.A. although occasionally Timken does supply us with some bearings from their overseas plants.

Areas of known interference are marked.  If you purchased one of these tailshaft housings from us prior to March 1st, 2006, you can return your tailshaft housing to us for credit.  There may be additional interference problems in the areas between the marks. 

All cast iron housings we sell are now checked for trueness before shipment.

Cast Iron  Tailshaft Housings are for those of you who off-road your NV4500 equipped Dodge trucks extensively, or have had the engine substantially increased in horsepower, or you have bolted on two speed auxiliary transmission.  For these applications, you should replace your original, lightweight 10.5 lb. aluminum tailshaft housing with this rugged   cast iron tailshaft housing kit. Complete and ready to install!  Includes The only Cast Iron housing double checked for trueness and with machined flat bolt seats. 8 genuine NVG retainer bolts, output seal, dowel alignment pins, and RTV sealant. QK1122 also includes 1/2" drive 12 point impact socket for tailshaft housing retainer bolts.  Tailhousing Imported but is finished and inspected in U.S.A.; seal, bolts, pins, socket, and RTV Made in U.S.A..

   Important! See Note Below if you have a cast iron tailshaft housing purchased from us prior to March 2006 or purchased from any other supplier at any time!

QK1039 Cast Iron Tailshaft Housing Kit NO Socket No Longer Available

PLEASE READ!!!!

We documented two major problems with Cast Iron tailshaft housings in March of 2006. Read our Tech Article to learn more!

There are a number of companies importing cast iron housings.  We have checked every make we could find and everyone single one has problems with either fit or bolt distortion (or both).  As of November 2009, 3-1/2 years after we brought the situation to light, we finally have found a company that has corrected the accuracy and transfer case fitment problems.  We are again offering our QK1122 and QK1039 Tailshaft Housing Kits using housings that we have both checked for accuracy and machined all 14 bolt seats.  With our additional labor input these are certainly not the cheapest housings on the market but they are the the only ones you can install with confidence.
