Go with the source engineering Bilsteens. They are the only shock made specifically for the roadmaster RR8 and RR10 chassis. I believe there is a version for.each plus front.and rear. I put them on my 2001 Windsor and they completely transformed the ride. My Monroe's were still.good.but the coach , especially the from end, ride so hard it would rattle.everything and made it.just unpleasant to drive. It was night and day after I put the SE Bilsteens on. Cannot recommend them enough. Give them call. They are worth every penny.
