Heavy-Duty 8-Blade 27" Semi-Elliptical Leaf Spring (1,500kg Pair Capacity)

The Heavy-Duty 8-Blade 27" Semi-Elliptical Leaf Spring is a commercial-grade trailer suspension component engineered to provide robust payload support, progressive road damping, and dependable axle tracking for medium-to-heavy commercial trailers, touring caravans, heavy utility haulers, and agricultural transport chassis. Rated for an axle capacity of 1,500 kg per pair (750 kg per individual spring assembly), this 8-blade spring stack utilizes an industry-standard 27-inch (~685 mm) mounting span to deliver exceptional load-bearing strength, high roll resistance, and stable tracking across both paved highways and rugged unpaved terrain.

Constructed from oil-quenched and tempered high-tensile automotive spring steel, the 8-blade graduated architecture absorbs vertical road impacts and cyclic dynamic shock while preventing bottoming-out under demanding payloads. Built in a classic eye-and-slipper layout, the rolled forward eye anchors securely into the front chassis bracket for positive trailing-arm axle geometry, while the rear slipper tail glides freely inside the slipper channel to allow unrestricted longitudinal travel under compression.

Key Features & Benefits:

• High-Capacity 1,500kg Combined Rating (Per Pair): Calibrated for medium-to-heavy commercial trailer applications, supporting up to 750 kg per individual spring assembly across standard single- or tandem-axle chassis.

• 8-Blade Graduated Multi-Leaf Stack: Dense multi-layer construction progressively absorbs vertical road impacts and dynamic vibrations, shielding chassis crossmembers, welds, and payload from stress fatigue.

• Industry-Standard 27-Inch Span (~685 mm): Standard dimensions ensure drop-in compatibility with commercial slipper spring chassis hangers and standard axle tie-down hardware.

• Controlled Articulation & Reduced Rebound: Eliminates harsh trailer skating while maintaining firm, stable tracking under heavy payload.

• High-Tensile Quenched & Tempered Spring Steel: Heat-treated automotive spring steel provides fatigue resistance, structural elasticity, and long-term retention of arch camber under repeated cyclic loading.

• Standard Eye-to-Slipper Orientation: Front rolled and bushed eye anchors securely into the forward chassis hanger for accurate axle tracking, while the rear slipper tail expands freely inside the rear slipper guide.

• Lateral Stability & Roll Control: Multi-blade profile provides rigidity against lateral twisting forces, reducing trailer body roll and sway during high-speed cornering or in strong crosswinds.

Ideal Applications:

• Commercial & Utility Trailers: Running gear for single- and tandem-axle goods trailers, commercial flatbeds, and equipment haulers.

• Heavy Touring Caravans & Campers: Suspension engineered to deliver stable towing and protect internal cabinetry, appliances, and onboard fittings from road vibration.

• Livestock Transporters & Horseboxes: Durable running gear built to handle dynamic animal movement while reducing body roll and trailer sway.

• Agricultural Implements & Farm Utility Carts: Running gear for field runabouts, mobile fuel bowsers, and farm service trailers operating over unpaved terrain.
