The Roadmaster Comfort Ride Shocks can be purchased separately with part # RM-204000-00. We unfortunately don't sell the mounting hardware separately so you would either have to purchase it directly from Roadmaster or from your local hardware store. I've listed the hardware use to mount the shocks below:
24x M12 flat washer
8x M12 x 1.75 x 100mm bolt - class 8.8
8x M12 x 1.75 nylon insert lock nut - class 8.8
8x 1/2" spacer view full answer...
