Rear dampers are among the simpler suspension jobs — upper and lower fasteners only. Support the axle before removing the old units so the spring or leaf pack does not hang on the brake line. No wheel alignment is required for a rear damper change on its own.
Dobinsons has been designing and manufacturing 4WD suspension in Australia for decades, with springs wound and dampers valved for local loads, corrugations and touring distances rather than adapted from an overseas market spec. Every part is backed by a Dobinsons manufacturer warranty. View the full Dobinsons range to match the rest of your build.
