Heavy-Duty 8-Blade 36" Double-Eye Semi-Elliptical Leaf Spring (2,000kg Pair Capacity)

The Heavy-Duty 8-Blade 36" Double-Eye Semi-Elliptical Leaf Spring is a commercial-grade trailer suspension component engineered to deliver strong payload support, positive axle tracking, and supple shock absorption for commercial transport trailers, equipment haulers, touring caravans, horseboxes, and livestock transporters. Rated for a combined load capacity of 2,000 kg per pair (1,000 kg per spring), this 8-blade spring stack is built in a double-eye configuration across an extended 36-inch (~914 mm) eye-to-eye span, offering a smoother, less jarring ride than shorter packs while maintaining firm, stable roll control under heavy payloads.

Unlike single-eye slipper springs that slide freely in a rear chassis pocket, the double-eye construction features rolled and bushed eyes at both ends of the main leaf. This dual-eye setup links directly to a fixed forward chassis hanger and a rear pivoting shackle link (or center equalizer rocker beam in tandem-axle applications). By capturing both ends of the spring assembly, the setup positively locates the axle, prevents fore-and-aft axle displacement during aggressive braking, eliminates metal-on-metal slipper slap, and delivers stable, quiet articulation across rough gravel roads, corrugated farm tracks, and highway routes.

Key Features & Benefits:

• Dual-Bushed Double-Eye Configuration: Rolled spring eyes on both ends secure the spring between a fixed front hanger pin and a rear shackle link or equalizer bar, maintaining positive axle alignment and eliminating slipper clatter.

• 2,000kg Combined Load Rating (Per Pair): Heavy 8-leaf stack provides dependable load-bearing support for up to 1,000 kg per individual spring assembly, making it suitable for medium-to-heavy commercial haulers and multi-axle trailers.

• Extended 36-Inch Span (~914 mm): Longer arch length provides greater vertical deflection and flexibility compared to standard 27" springs, softening road shock and protecting trailer bodywork and cargo from severe impacts.

• Controlled Axle Alignment Under Braking: Positive double-eye anchoring restrains axle twist and fore-and-aft deflection during sudden stops, ensuring balanced braking and reduced tire scrubbing.

• Tandem-Axle Rocker Integration: Seamlessly integrates with center rocker/equalizer bars in multi-axle suspension setups to distribute loads evenly across both axles when traversing uneven ground.

• High-Tensile Quenched & Tempered Spring Steel: Manufactured from automotive-grade heat-treated spring steel to resist sagging, blade fatigue, and loss of camber under cyclic loading.

• Superior Roll & Sway Resistance: Multi-leaf architecture provides high lateral rigidity, stabilizing top-heavy loads, livestock, and high-sided trailers during high-speed cornering or in strong crosswinds.

Ideal Applications:

• Commercial & Plant Trailers: Heavy running gear for tandem-axle plant trailers, machinery haulers, equipment transporters, and commercial flatbeds.

• Touring Caravans & Expedition Campers: Extended-span suspension delivering a compliant, quiet ride that cushions onboard appliances, cabinetry, and internal fixtures against vibration.

• Horseboxes & Livestock Transporters: Double-eye mounting delivers smooth, quiet articulation that reduces animal stress and controls lateral sway on rural roads.

• Enclosed Cargo & Freight Haulers: High-capacity running gear for multi-axle box trailers, furniture movers, and logistics freight haulers.

• Agricultural Implements & Farm Trailers: Chassis suspension for tractor-drawn machinery, bulk produce carts, and mobile service platforms operating over rough terrain.
