I was gonna use all Redline fluids so was wondering which Redline fluid I'm suppose to use for the t-case and rear diff since they need to be LSD fluid? Thanks.

 

I would stick with the OEM Diaqueen on both rear diff and the tcase.

 

If you do want to use Redline: 75W-90 in transfer case/rear diff.

 

I don't need to include the LSD additive with Redline 75W-90?

 

Road Race Engineering put Redline Heavy ShockProof gear oil in my transfer case and rear diff. I wouldnt put any other oil than Oem diaqueen, redline shock proof, and royal purple max gear. Never heard of anyone adding lsd additives. Most people here are gonna tell you to use oem diaqueen.

 

Only use OEM in the t case unless you have an aftermarket front diff.

 

I had all amsoil put in when I changed all the fluids last

 

^ same, dunno about it making a difference though

 

i just bought redline heavy shock proof fluid for the t case and rear diff. do i need the lsd additive for the rear diff?

 

Im about to change my fluids later this week and im not sure what to put for my t-case and diff. Im leaning toward redline heavy shock proof. Any pros and cons?

 

I am changing my rear diff this weekend with ams oil 75-90 severe gear oil. I have read good things about it. It is also used in the t-case.

 

use only redline shockproof heavy or oem diaqueen lsd in TC and redline 75 90 in rear dont use the 75 90 NS

 

I have been running amsoil for 10k in my tranny and t-case with no issues. Redline is good too.

 

yep amsoil severe gear in tranny and transfer case, amsoil manual trans fluid for tranny

 

OEM fluids are the best to use. But with talking to Shepard, he says it depends on how much HP you are running to which to a different fluid. With higher HP cars he says to use Redline stuff
