It's a factory NA 5-spd. What I'm torn between is putting a TRD LSD in my 4.27:1 diff or buying a 4.08:1 NA diff instead (and putting the TRD LSD in it).They should fit into the differential just fine, but be sure that the axle stubs will bolt to the axles - sometime in the '97 production year, NA VVTi cars went to a smaller diameter stub and wimpy little tiny ass axles.
If needed, the stubs and axles from a 92-96 SC400 work wonderfully in a JZA80 running a small diff.
97-98 NA's are still throwing wild cards at times. I suspect there's a difference between the auto and 5-spd cars. So far I haven't seen the diff code itself steer anyone wrong.
I strongly suspect you have a 4.272:1 being an A05A. The last letter is a clear and very consistent identifier for LSD or no, and the 'A' always means it's an open differential.
Is your '97 a factory NA 5-spd or NA auto?
Personally I would get a later model Lexus 3.769:1 open (06-10 SC430, etc, other 3UZ-FE models with the 6AT trans) and install the TRD LSD in that. The later Lexus diffs have beefier casings than the Supra or early SC differentials anyway.It's a factory NA 5-spd.

This would be for the Grannas T56 swap.
Did you confirm the SC430 diff came from an SC430, and did you confirm the 3.266:1 ratio? If so, do you know exactly what year SC430 it came from?So I have an 1993 NA. I'm getting ready to do a 6 speed swap in the next few months and I bought a rear diff off of an SC430 to have a better matching final gear. I dropped my diff out and compared the two and the flanges are the same size and the donuts can both be swapped over too. I put the sc430 diff up and it bolts in perfectly to the driveshaft. From what I read the NA diffs are small flange and the SC430 diffs are big flange so I was ready to swap them. Does anyone know the measurement of the flange so I can see if I been ripped off or if I bought my car with a big flange diff?
The OS Giken Super Lock LSD is a wonderful upgrade and superior to all other available options. Bearings and other support parts are still available.I've been digesting most of the info in this thread. A diff rebuild is needed for our Supra. Since it is 3.133:1 (B07D?), I'd like it to stay that way but see that TRD diff parts are discontinued and other brands don't seem to be for the "big diff" (220mm ring gear differential) and big flange setup that we have. What are folks doing in this situation? I supposed we could just go the OEM route but I'm worried about reliability.
I should have responded to this earlier.Hi Jeff,
I'm wondering if the 8" truck 200 MM gear/pinion is the same as the mk4 200 mm or the mk3 200mm there are plenty of pre tacoma's that have low ratios like 3.5 / 3.4 I've found and I'm wondering if I can use these ring gears.
