This Monroe Complete Strut Assembly replaces the original equipment unit on Mazda BT-50 4x4 models built from 2017 to 2019. Extended length is approximately 545mm and compressed length 384mm, matching the factory mounting geometry. The Nitrogen Gas Charged construction uses a 50mm piston bore with a multi-stage valve stack tuned for laden and unladen comfort. 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. Twin-tube gas pressurised design resists aeration and fade on corrugated dirt roads. Fitting is a straightforward workshop job and no coding or calibration is needed. Supplied new and backed by a 12 Months warranty.
