Hi everyone. Long time since I last posted on this site. I used to own a 92 LS400, but had to sell it due to money problems at the time. Thankfully I am better off now and am looking to get myself another car, and an LS400 is one of my two options. I am looking into a UCF10.

My old LS was an open diff. Upon researching, all LS are open diff. I loved the long gears, but wasn’t a ton of fun on the street. I was thinking, if I wanna buy another LS, I have to swap in a better differential. That’s all I need.

I would like to know what year Supra differentials will fit. I know there is a 4.27 ratio diff that doesn’t look to hard to get to fit, and I would obviously look for a limited slip unit. Do SC diffs fit? If so what years?

I really need any details on diff swaps on these cars. Internet searches haven’t yielded good results for me. If I am able to get a fun diff that will really give the Lexus more punch, that may be all I need to make up my decision on my next car. Thanks everyone!
