aro springs
I have been using 200 lb 8" long 1 7/8" ID springs in front and rear on ARO. You can actually run 10" long springs on the front.
Off SOUTHWEST SPEED $50 with shipping.
On the old style TS YAMAHA imitation sliding no/scissor rear suspension, seems like 225# springs are about spot on.
Stiffer springs will straighten out a lot of trail manners, go through powder better, and yes.....save your back.
