700R4 Spacer


This spacer is used to put a 700R4 in place of a TH350, or to put an NP203 or NP205 behind a 700R4.  NP203 and NP205 transfer cases commonly came behind TH350 transmissions, but they never came behind 700R4's.  The 700R4 shares the 27 spline output and 4 bolt pattern with the TH350 but it's output is about 2" longer.  To adapt a 203 or 205 to a 700R4, you can install this spacer OR use this shorter replacement output shaft.  Once the length is taken care of the TH350 parts will bolt right up.

If you're installing an NP203 behind a 700R4, you will need this spacer and a TH350 to NP203 adapter.

If you're installing an NP205 behind a 700R4, you will need this spacer, a TH350 to NP205 adapter and a 27 spline drive sleeve.

Minor trimming of the transmission output shaft is normal, bolts included.
