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.

NP205 Complete Rebuild Kit:

Full Rebuild kit for NP205, includes a seal and gasket kit

For GM NP205's, all are the smaller (80mm) 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 (90mm) bearing.

For Dodge NP205's, all are the smaller (80mm) input bearing except 205's behind Getrag 5 speed manual transmissions in 89-93 Dodge Cummins equipped trucks.  Married Dodge 205's use a special (and unfortunately kind of expensive) front output seal, see below.  That will need to be added in addition to the rebuild kit.

For Ford NP205's, married versions use the large (90mm) input bearing and divorced versions use the smaller (80mm) input bearing.

Adapter Reseal Kits

TH350/205 systems commonly fill the 205 with ATF because of bad seals, so we came up with a kit to re-seal the 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 - $135.00

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 spline yoke.

Lomax 3:1 gearsets

**Not currently available, no ETA**

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.

The Lomax 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.

The Lomax 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.

Price is $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 details.
