I have a 2010 ,420 and need a stronger rear shock… SRA ……. Highlifter doesn’t make a shock and spring. Only offer a spring. For my bike…. I carry around 400 pounds at times … Spray tank ….. I had a 350 with a Highlifter shock and spring and had a spacer added to the set up. It was just what I needed. A 350 shock is only 15" long ,,,,,,, Now I need my 420 to carry the load. The current shock is apx 17 1/2" form hole to hole. Any of u know of a shock – spring that would fit that dimension. I already have spacers.

Therefor I’m looking for any bike year or size that has a single rear shock with roughly a 17 1/2" hole to hole length
