13+ inch heavy duty shocks

I need some heavy duty shocks for my rupp. I need something that wont allow the rear fender to rub with my fat ass on it. What do you have?
I actually had 2 random shocks that one was 13" and the other was 13.5... Mismatched I know. I tried them and they are plenty stiff. Now if I can just find some shiny new ones that are the same length,that would be nice..lol
But Dougs not 350 pounds..lol.. I bought them. I'll try them. If they bottom out I'll toss the old motorcycle ones on for the fields.
