Heavy-Duty 1,300Kg Green Suspension Damper (900kg – 1,300kg Axle Capacity)

The Heavy-Duty 1,300Kg Green Suspension Damper is a precision-calibrated hydraulic shock absorber engineered to provide dynamic oscillation damping, ride compliance, and vibration suppression for medium-duty commercial trailers, touring caravans, camping haulers, and utility equipment. Color-coded in green for immediate identification of its load rating, this damper is calibrated specifically for axle assemblies operating within the 900 kg to 1,300 kg gross axle weight range.

Designed with an extended length of 339 mm, a fully compressed length of 217 mm, and an active stroke of 122 mm, the unit is optimized for an unladen installation center-to-center mounting distance of 330 mm. By rapidly absorbing and converting cyclic spring rebound forces into dissipated thermal energy, the damper keeps tires firmly planted on the road surface, reduces erratic empty-trailer bounce, controls body roll during cornering, and shields both the trailer chassis and onboard cargo from road-induced structural fatigue.

Key Features & Benefits:

• Tuned for Medium-Duty Running Gear (900kg – 1,300kg): Internal hydraulic valving is specifically calibrated for single-axle (or matched tandem-axle) trailers rated up to 1,300 kg, preventing under-damped bounce or over-damped harshness.

• 122mm Extended Working Stroke: Built with a maximum extended length of 339 mm and a minimum closed length of 217 mm (measured hole-to-hole center) to accommodate generous suspension travel.

• Optimized 330mm Mounting Position: Engineered for an unladen installation distance of 330 mm between eye centers, ensuring adequate travel reserve in both compression and rebound directions.

• Continuous Road Grip & Safety: Eliminates wheel hop over potholes, gravel corrugations, and speed bumps, ensuring consistent braking performance and directional tracking.

• Roll & Sway Mitigation: Damps sudden lateral weight transfer to minimize trailer snaking, crosswind disturbance, and body lean during highway transit.

• Structural Fatigue Protection: Absorbs high-frequency road vibrations, protecting chassis welds, drawbars, and delicate cargo from stress-related damage.

• Color-Coded Green Housing: Provides fast visual verification of the damper's load rating during assembly, fleet servicing, or replacement.

Ideal Applications:

• Medium Commercial & Utility Trailers: Running gear for single-axle braked goods trailers, trade haulers, and general commercial platforms.

• Touring Caravans & Camper Trailers: Damping upgrade engineered to smooth road shock, protecting internal cabinetry, kitchen fittings, and delicate onboard appliances.

• Horseboxes & Livestock Transporters: Delivers a settled, quiet ride that reduces animal stress and fatigue over unpaved rural tracks.

• Boat & Marine Trailers: Companion damper for medium-sized runabouts and watercraft trailers, stabilizing long drawbars and reducing hull shock during road transport.
