We offer a Manual shift conversion kit for the Ford NP271 transfer cases found in 1999-2010 F250 F350 F450 and F550 trucks and excursions.
This shifter kit will also fit the transfer-cases from 11-16 behind the 6 speed auto .. model MP1628F , and will not fit the BW cases with the shift motor on the back . Refer to Behemoth drive train for kits to convert those .
I am the Original designer and manufacturer of this kit , Made in the USA and use USA made parts and materials when ever possible .. there are multiple knockoffs on EBAY, Amazon and other places selling a copy of our OLD model kits .. We only sell the newest improved versions .
These can ONLY be purchased from our ebay store.

Shift rod comes extra long to account for all options as well as Cummins swaps that have the trans moved back 2-3″ (almost all installations WILL require you to measure and cut the rod shorter . will vary per truck / engine / trans combo )

The kits made after 6/25 are direct bolt-on (with no mods to transfer-case ) and can be done with transfer-case still in the truck . This gives you a manual shift 2wd , 4wd and 4×4 low .. the case does not have a neutral gear, instead it has a Synco assy to shift on the fly smoother and can still be used with auto hubs if you want to keep those.
The following is an install guide .. some parts have been updated so may look slightly different and photos are of a 99 Excursion .
To Install this kit , The servo unit needs removed , usually 3x 10mm head bolts . Next I like to shift the T-case with an adjustable wrench All the way back (toward rear of rig)
Now install lever and bolt on the cover with spacers on the back side as shown in above picture .
All floors already have the hole pre cut for the shifter , but its covered with a plate … options are to cut the carpet from the top or remove seats , carpet and (vents on excursion ) A glued down cover can be hard to remove .. vibrating saw works well to cut the glue.
07?+ trucks don’t seem to have the cover glued down, and may have the insulation pre cut out.
The mounting holes on the side of the transmission are usually filled with dirt and road grime and will need cleaned out well before mounting .. Best to mount to the hole that provides the best range of motion (often the rear of the 2 for a 4R100 or 5r110 with nut on backside ) (front hole is best for a 6R with washers on outside and nothing on back ) . F81Z-7277-BC is a shift boot for 99-07 trucks. The large washers are included if the bolt wont go deep enough or the shifter needs moved to line up better with boot . Following pics have 1 big washer installed behind shift lever bushing but you may need 2 if linkage rubs on transmission .
With shifter as far forward and you want it and the T case lever all the way back/rear , the adjustable rod with hiems can be marked/ test fit. It will usually need cut shorter as they are included extra long . The rod and hiems can be bolted together with the 5/16 bolts and lock nuts and test for operation. (T-case may not always shift easily between high and low in park)
Make sure the shift lever when its all the way forward does not contact the shifting linkage for the automatic (may only be a issue on 5r)
You will want to install Under part of boot with carpet and may need to mark for screw mounting holes . Make sure when shifter is all the way back it does not hit the seat (or center console if you have one ) when its slid all the way forward .
Shift pattern is all the way forward is 2wd high , One click back is 4×4 high , all the way back is 4×4 LOW .
