Looking to put a 3.26 from a 97+ sc400 into my 93 sc300. going 70mph my rpms are around 3k.

I currently have a trd, ive done differential work but im not sure if the differentials are 100% identical to swap my lsd center over.

later sc400 diff straight bolt in affair? companion flanges and axles all same? they are 75 bucks near me so was going to weld one and if i like the 3.26 ratio then ill swap my lsd.

thanks

Someone correct me if I'm wrong, but I believe them all to be direct swaps. You should be able to swap the LSD between units and install the 3.26 without modifying anything at all.

1997 SC400 has a 3.92 differential gear ratio . 1998-2000 SC400 has the 3.26 .

What is the size of your TRD LSD ? if it is 200mm it will fit any SC300 / SC400 pumpkin . If it is for the USDM 6speed which is 220mm .. no it will not
