hello I just bought a 2003 viper and need some help.I want to drop the rear suspension out and raise the rear and up a bit but I don't want to screw up the geometry. Can any body tell me how to do it properly or guide me to a company that makes a kit to do such a task. Thanx for any help .

The easiest way is get the shocks off of a xtc or sxr. they are longer and will raise the tunnel up. You may also need the metal straps that run down the sides of the rear shock. I dont know if those are the same length or not.

Viper shocks are the same as the XTC and SXR shocks. So that wwon't help you. Go to Totallyamaha.com and do a couple searches. Lot's more Yammie info over there.
