I want better ground clearance, I'm probably not gonna change the chassis, but I'm wanting more ground clearance.Do you mean you want to put a Ruckus body on your Amp?
For extra shocks are you wanting to add them for looks? If you put lighter springs and lighter oil in the shocks it should work fine as long as you can get the angles right. The big question is how do you want to change the handling and suspension? Do you want longer travel and more damping for jumps? Higher ground clearance? Better handling on smooth surfaces?
