After hours searching back, I am still at a loss. We have an '03 Cummins reg cab w/ a winch and a set of Skyjacker 7" coils on a Kelderman long arm kit. The RS9000's we run wear out fast w/ poor performance. So we are looking to replace w/ Bilsteins. Do they even make a shock that long in the HD's or the 5100 series? Maybe someone has a part # for them that has the same size lift? Any recommendations aside from Bilstein? We need shocks fast as the truck is apart in the driveway because the local 4x4 shop ordered the wrong size shocks and we didn't figure it out till we went to put the new ones in. Thanks.
