I'm needing a new drive shaft for my 86 250sx and noticed the part # on the yoke is different from an 85 to 86,anyone know if they still can be swapped? Theres a ton of 85 shafts but hardly any for 86's around.

I've seen no visible changed in 85/86/87 driveshafts....

The Big Red isn't the same at all though....

even the trx250 shaft is the same i have one in my 85 sx from a 86trx250

Are you sure it's the same? The driveshaft from an '86 TRX250 is about three inches longer than one from an '85 ATC250SX.

I don't recall if both ends are lengthened or just one side.

i have the whole rear swingarm, axle and diff from a 85 trx in my 85 250 sx i mixed up the years, the swingarm is the same for that year and attaches to the drive with the same boot. unless i got a trx that had a sx swingarm installed. now i have another trx that the swingarm is diffrent i will have to post pics of the two styles and see if anyone knows.

The problem is finding a good drive shaft. There out there but you will have to look. This is a vital sealing point of the rear end.

This is what most look like.

This is what they should look like.
