I get to rebuild my NSG370 (yay!) and thought I’d rebuild the NV231 while it’s out. What kits do you like and what chains are you using? I’m hesitant to get any cheap crap.
 
Any updated kit preferences?

on the 97, I'm thinking of having the TC rebuilt as we'll be putting on the SYE kit and both new front/rear DS.

@Doctor Bone Smash ... did you install the kit you mentioned? Pros/cons??
 
JB Conversions has a master and partial rebuild kit too, I haven't used it but their SSSYE is regarded as high quality and they use a Borg Warner chain

What is there to really rebuild? A chain stretches over time so not a horrible idea, but if everything else is intact, I'd say save your money.

Yup ... however, since the tcase will be open and partially disassembled for the SYE, i figured might as well spend the few bucks for some peace-of-mind later.

I'm thinking bearings and seals, and there's that plastic thing near the shift forks iirc.
 
I understand the "while its out" mentality. But failing tcase internals are not very common.

The other thing about the 97 is that when I changed out the heater core and took apart the dash, I learned the PO might've taken this thing in some deep water. Some interesting water level lines. After finding that out, I've been upping my schedule to work on replacing parts sooner than later.

Already got the 5.13s, new axles, new wheel bearings, new brakes, complete new exhaust within the last 12 months. Working on complete steering hardware replacement, SYE, TC rebuild and DS replacement in the next 3-4 weeks. Hopefully removes any unseen damage and gets it ready for warm weather fun.

I went with it. No difference noted. They include Timken bearings and I got the Borg Warner chain also. It works like stock.

Mine needed shift fork bushings, several bearings, a chain that was skipping in lo. And oil seals. If they were abused and neglected, they need everything.
 
I believe it's internals from a dodge version with the wide chain and sprockets.
