Transmission Conversion Kits
For 1989-'93 Dodge Trucks to Replace the Getrag G360 |

As of APRIL 2007, we have discontinued
manufacturing our NV4500 Conversion Kits.
This was a difficult
decision because the Getrag to NV4500 Conversion was our
original QuadKit and the one that transformed our business from
a local 4x4 shop to what it is today. However, the rising
demand for our 4x4 Special Tools requires using all our
manufacturing capacity to produce those tools, so we no longer have
time to devote to making conversion kits. We do have a few
components for these conversions which we will list for sale on
this page as time permits.

Dodge 4x4 Cummins Diesel Automatic to Manual Conversion
Information
We get a ton of requests for NV4500 and NV5600
Conversions on 1989-2002 Dodge 4x4 originally equipped with
automatic transmissions. This is not quite so simple as it
sounds because of transfer case incompatibility. For all trucks
with NP205 transfer cases and most newer models with NP241
transfer cases, the transfer case input shaft is only a 23
spline and the manual transmissions have a 29 spline output
shaft.
With the NV4500, we can install a
Torque King™ 23 spline output
shaft although this is not as strong as the 29 spline shaft. The
best option is to install a 29 spline input shaft in the
transfer case. This is pretty straight forward with the
NP241, however it is not so simple with the NP205 found in
1989-1993 trucks. For these models, the bores for the
input bearing and transfer case adapter must be enlarged by a
machine shop to accept a larger bearing and seal, plus you will
need to get a 29 spline female coupler shaft to join the
transmission output shaft to the transfer case input shaft.
Our QK2001 has
the pieces required to convert your 23 spline NP205 to 29
spline.
In addition to the
transfer case modifications, you will need a new flywheel,
flywheel bolts, clutch
assembly, clutch bolts, bellhousing (NV4500 only), clutch fork,
clutch hydraulic system, clutch pedal, brake pedal, transmission
mount, transfer case linkage, and hardware. You will need
to cut the cab floor/carpet to accept the shift tower, rewire
the backup lights and cruise control. In most cases you
will also need to have driveline modifications done. Some
models will also require crossmember relocation. NV5600
conversions in 1989-1993 trucks will also need a new
flywheel housing.
and custom starter as will first gen trucks using 1994 and newer
bellhousings.
Unless you have a
donor truck to cannibalize most or all the parts from, this is
one expensive conversion. NV4500 conversions will run
$6,000-$7,000 for all new parts and NV5600 conversions are even
more expensive. |
