G'day YZ250H,
The YZ'J shocks are all the same except when it comes to spring rates and the lengh of the reservior hose.
The 125 hose is about 1.5'' shorter then the 490. I do have one 490 hose left.
NOS parts that I have listed are all YZ'J shock rebuild parts and all interchange with the 125,250,490.
The shock I have listed Reads 5X4 - 125 J.
Last night found NOS cleaves that screws onto the end of the shaft, and also come across NOS spring ... it's got a dob of red paint on the end of it - not to sure what rate this would be.
I would happy to include these two bits in the sale.
Cheers
Rob.
