ok there is a few things i know about the two tranis, 151s gear t-case vs a chain t-case in 150. and i believe there is more spline on the output shaft of the 151 than the 150. i wanna gear way down in the diffs but still be able to run 80-85 on the highway without tapping out when i to a 7m na conversion. also i wont be doin much crawling, but will be deep sno driving in the winter. mainly it will be a desert truck so what would yall who are good with tranis recommend? thanx

The R150 and R151 both have large output shafts. The difference between th e two is the tail housing.

The R151 is for use with a gear driven t-case, and the R150 is for a chain driven t-case.

There are no options for gearing down on the chain driven as there are with the gear driven. Problem is, the R151's are hot and people want a premium for them. Plan on $700 for an R151.

ok to get this right if the t-case is not an issue due to no heavy crawling needed, the 150f is a better and cheeper bet. gearing of the trani itself and the torque tollerances of the shafts are my biggest worry... thanx so much

The R150 and R151 are equal in strength. Most people would prefer the R151 due to the gear driven t-case which is stronger than the chain driven, and that you can get a gear reduction of 5.0 from the stock 2.3.

R151 also has a VERY low first gear, which depending on your application, could be a good or bad thing.

Probably going to be around $400. Machine work ended up being a little more.

Glad I can help.

Yeah, back is still messed up. My doctor is parting with someone starting next month that does endoscopy. I am going to give that a try, hopefully there is at least some improvement. I don't care if it is just a little, some is better than none.
