Transfer Cases
« on: August 07, 2012, 06:26:31 am »
203 FullTime - its a decent strong case and works good for its intended design, used from 1974 to 1979 and some 80,s / there are some Part-Time kits available and they aint cheap or easy to install / besides you would hafta drive a million miles to recoup the little gas money you save to pay for the expense of the kit / Interchange - the 203 has a weird figure  eight bolt pattern and a different output spline count than any other t-case , so it does not swap out with any other t-case made , to change one out you either must also change the tranny or pull apart yours and change the output shaft and tail housing to run a 205-208 or 241 .also if you do change the 203 out you also haft worry about or change the full-time frontend , mainly because the newer t-cases are not designed to spin full-time.  basically if you have a good running full-time truck leave it alone , grease the front wheel bearings and be happy

205-208-241 Part-Time

205 - Divorced / comes in 1972 thru 1977 ?? trucks 3/4 ton and up and only fits in a divorced truck without lots of Mods
205 - Married / fits in 1981 to 1993 trucks / its STRONG and HEAVY and does not have a very good low range gear ratio of 1:96
summary / its basically a HIGH horse power BIG tire mud bog t-case and does not work well for normal trail wheeling

208 - the first of the new style aluminum light weight t-cases / 1981 to 1987 ?? / its plenty strong for most wheeling and has a decent low rang gear ratio of 2:61

241 - 1988 ?? to 1993 /  this is by far almost as strong as a 205 but light weight aluminum like the 208 but twice as strong with a gear ratio of 2:72

all three t--cases interchange with each other
