rear shock

[pa400]

since people put 450r shock on the front can you do it to the back one because i want to do that

[powermadd400ex]

you can, but its screws up the handling.
a stock 400 shocks performs better than the stock 450r shock on an EX .

Send off the stock shock to GT Thunder and they will set it up for you for about 375

Or keep your eye out on Ebay. I gotta PEP dual rate for a steal, and you can use your stock linkage. Can't believe how much difference it makes. It also give you a lower sag.
