85 250sx differential compatabilty

[1985250sx]

Hello guys,
first off wasn't sure whether to post this here or in the ebay forum, but im looking to buy a differential for my atc and found a pretty nice looking one on ebay. Its listed as an 87 trx250 rear end but also has others, including 85sx in the title so I just wanted to double check and see if these were compatible or if the seller is just trying to get more hits. thanks! heres a link

The TRX diff is the same gearing as the ES. The SX gearing is unique to only the SX. The ES/TRX ring gear is one tooth larger so you will loose a little top end but gain torque on the bottom end.

My cousin has a 250sx with a big red 250es rear end, that thing is a crazy wheelie machine vs my stock 250sx. I don't think he loss much top end speed, but he gets there a a bit quicker than me. probably top speed of ~52mph vs mine at 55mph.
