Can anyone help me? I'm trying to find a heavier rear spring for a '02 scrambler 500, it has a fox shock and no one seems to be able to find one.

 

Hot Seat Performance make a dual rate spring for the rear shock and the Front Struts. I have heard the work really well. They Add more Progressive spring rate with Improved bottoming resistance.
