How to get a smooth ride for my sand rail
 

My wife has been bugging me for a sand rail but the dang thing was built to were it is so stiff it will beat you to death.

Is there any cheap routes to go to get it to have a more smooth ride on the street. She is not using it for off road, just to cruise the beach highway.

If you could share some ideas or point me to the correct parts i would appreciate it.
