The Tough Dog Rear Shock Absorber is a direct-fit replacement for Toyota Corolla models built from 2019 to 2021. Bushes and mounting hardware are supplied where the original unit was fitted with them. Twin-tube gas pressurised design resists aeration and fade on corrugated dirt roads. The Steel construction uses a 30mm piston bore with a multi-stage valve stack tuned for laden and unladen comfort. Rod diameter is 20mm with a hard chrome finish and a multi-lip seal package to keep dust out. 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. This part is a common wear item on high-kilometre Australian vehicles and is worth replacing in pairs. New stock, 2 Years / 40,000 km warranty, and dispatched from our Australian warehouse.
