Heavy-Duty 1,800Kg Blue Suspension Damper (1,300kg – 1,800kg Axle Capacity)

The Heavy-Duty 1,800Kg Blue Suspension Damper is a precision-calibrated hydraulic shock absorber engineered to provide controlled dynamic damping, ride stability, and vibration suppression for commercial transport trailers, heavy touring caravans, horseboxes, and equipment haulers. Color-coded in blue for instant load-range identification, this damper is calibrated specifically for trailer axle ratings between 1,300 kg and 1,800 kg, absorbing road shocks and suppressing resonant spring oscillations that lead to erratic trailer bounce and instability.

Engineered with an extended length of 339 mm, a fully compressed length of 217 mm, and a total stroke of 122 mm, the unit is optimized for an unladen installation center-to-center mounting distance of 330 mm. By converting dynamic kinetic energy into thermal dissipation, it maintains continuous tire contact with the road, stabilizes the trailer against severe crosswinds and cornering body roll, and protects the trailer chassis, running gear, and onboard cargo from structural stress fatigue.

Key Features & Benefits:

• Tuned for Heavy-Duty Running Gear (1,300kg – 1,800kg): Internal hydraulic valving is calibrated specifically for single axles rated up to 1,800 kg (or tandem setups within range), preventing harsh under-damping or excessive stiffness.

• 122mm Extended Working Stroke: Built with a maximum extension of 339 mm and a compressed length of 217 mm between hole centers to accommodate wide-deflection trailer suspension travel.

• Optimized 330mm Mounting Geometry: Engineered for a recommended unladen eye-to-eye installation distance of 330 mm, maintaining optimal stroke margins for both compression and rebound.

• Maintains Continuous Tire Contact: Minimizes high-speed rebound hopping over washboard gravel and potholes, preserving braking grip, directional control, and even tire wear.

• Suppresses Body Roll & Snaking: Effectively dampens sudden lateral weight transfers during highway cornering, emergency maneuvers, or high-speed crosswinds.

• Kinetic Energy Dissipation: Converts harsh suspension impacts into heat, insulating chassis crossmembers, welds, and delicate payloads from repetitive cyclic fatigue.

• Color-Coded Blue Housing: Provides fast visual verification of load class and application matching during installation, maintenance, or fleet inspections.

Ideal Applications:

• Heavy Commercial & Freight Trailers: High-capacity running gear for single- and tandem-axle flatbeds, plant equipment trailers, and box trailers.

• Large Touring Caravans & Campers: Supplementary damping to protect internal cabinetry, onboard appliances, and structural panel seams during long-distance highway and gravel-road transit.

• Horseboxes & Livestock Transporters: Damps sharp suspension jolts to ensure a smooth, stable ride that reduces stress and fatigue on transported animals.

• Boat & Watercraft Trailers: High-capacity marine trailers needing controlled rebound behavior to protect hulls when trailering over rough access routes.
