Transfer Case Parts
NP205 input conversion Kit:
Convert your male input NP205 to a TH400 version 32 spline short
female input gear. Kit includes new input gear, input
bearing, input bearing snap rings and a complete seal and gasket
kit. Requires machine work on the NP205 case to install,
the input bearing bore must be enlarged by 10mm compared to the small bearing.
#GU4033 - $190.00
NP205 Complete Rebuild Kit:
Full Rebuild kit for NP205 (specify large or small input
bearing), includes a seal and gasket kit
For GM NP205's, all are the smaller input bearing expect 205's
coupled to TH400 automatics (all years) and SM465 manual transmissions from
85-91 K30's (these use the round bolt pattern on the 205) which
use the larger bearing.
For Dodge NP205's, all are the
smaller input bearing except 205's behind Getrag 5 speed manual
transmissions in 89-93 Dodge Cummins equipped trucks.
For Ford NP205's, married
versions use the large input bearing and divorced versions use
the smaller input bearing.

NP205 Seal and Gasket Kit:
and gasket kit, covers any NP205 (includes figure 8 adapter
gasket but no adapter seals)

Adapter Reseal Kits
systems commonly fill the 205 with ATF because of bad seals, so
we came up with a kit to re-seal the adapter system.

Reseal kit for figure 8
TH400/NP205 ('84 and older) adapter system

NP205 output shafts:
We now have NEW 32 spline front output shafts for the NP205.
The 32 spline shaft is a big strength upgrade over the early GM
10 spline and is also stronger than the GM 30 spline shaft.
Another big advantage for the 32 spline front output is the fact
that you can get just about any yoke you want for it since it
takes the same yokes as a 205 rear output.
NEW 32 spline front output shaft for NP205, direct swap into
most GM 205's, fits rare 80's syncro 205 with additional parts #GU4083 -

NP205 slip yoke output conversion kit:
Some later model NP205's came with a slip yoke rear output
that's generally less desirable than a fixed yoke type output.
We have a kit that includes a new output shaft, new output seal
housing/bearing retainer and the seals and gaskets necessary to
install the parts. The output shaft is a stock part and
accepts all stock output yokes and virtually any aftermarket 32

Lomax 3:1 gearsets
The Lomax kit converts your NP205 from a 2:1 low range to 3:1!
A complete replacement case is included with the kit as the
deeper gears do not fit a factory case. The Lomax gears
are available for GM/Dodge applications only, Lomax 3:1 gears
are not available for Ford NP205's.
case is drilled for both the figure 8 and the 6 bolt round
patterns and 10, 27 and 32 spline input gears are available.
There are no divorced options available for the Lomax gears.
kit is a great option for applications that need to be very
short, where adding a gear box in front of the 205 is too long.
The Lomax kit is also a great way to get the rare 6 bolt round
face pattern. If you can add an auxiliary gear box (like
our 203/205 doubler or our Magnum underdrive) those are
typically more cost effective and you get more out of it.
$1629, you will need shift rails, clutch rings, output shafts
etc from an NP205 to completely assemble a Lomax 205. We
can build you a complete Lomax 205 as well, call or email for
category you would like more information on.
