This Tough Dog Rear Shock Absorber replaces the original equipment unit on Isuzu D-Max models built from 2018 to 2020. Damping rates are set slightly firmer than standard to control body roll with a loaded tray or roof rack. Bushes and mounting hardware are supplied where the original unit was fitted with them. Rod diameter is 18mm with a hard chrome finish and a multi-lip seal package to keep dust out. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. We recommend fitting by a qualified technician and following the manufacturer's torque specifications. Check the fitment list against your build date and VIN before ordering, as running changes were made mid-generation. Fitting is a straightforward workshop job and no coding or calibration is needed. Every unit is supplied new with a 24 Months warranty against manufacturing defect.
