Is the Big Red Rear Differential Same as TRX 250'S

[ClayW]

Anyone know if the rear differential in a 250 big red and a trx 250 are the same. Thanks the info would be very helpful.

A couple years ago I found out the cases are slightly different. To use a ATC dif on a TRX you need to machine out a little of the case where the left side tube slides in. If your putting a TRX dif onto a ATC then you should be able to just bolt it up and go. I am not 100% sure if the gears are the same, but on the one I did ( ATC to a TRX ) it worked just fine. ;)
