ls ys1 tranny

[.:Stirfry:.]

all b series clutch kits are the same. but the flywheels mAy differ

[cardesignz]

A1, S1, Y1, and J1 transmissions must use a 90-91 clutch disk (smaller size input shaft)

92-93 YS1 transmissions and all 94-01 (hydro) transmissions use a 92-01 clutch disk (larger size input shaft)

pressure plates, flywheels, and pilot bearing (the one in the center of the flywheel) are all interchangeable

90-93 cable transmissions all use the same throw out bearing. 94-01 hydro use a different throw out bearing.

So, if the transmission is an actual YS1, you need to make sure you have a 92+ clutch disk or it won't fit.
