Heavy-Duty 10-Blade 36" Double-Eye Semi-Elliptical Leaf Spring (2,500kg Pair Capacity)

The Heavy-Duty 10-Blade 36" Double-Eye Semi-Elliptical Leaf Spring is a high-capacity, commercial-grade trailer suspension component engineered to deliver substantial payload support, precise axle tracking, and extended deflection damping for heavy commercial transport trailers, agricultural equipment, industrial plant haulers, touring caravans, and horseboxes. Rated for a combined load capacity of 2,500 kg per pair, this 10-blade spring stack utilizes an extended 36-inch (~914 mm) mounting span in a double-eye configuration, combining high-load carrying capability with the road-smoothing characteristics of an elongated suspension arc.

Unlike standard slipper springs that slide freely in a rear pocket, the double-eye construction features rolled and bushed eyes at both ends of the main leaf. This design links the spring securely to a fixed forward chassis hanger and a rear pivoting shackle link (or center rocker equalizer 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.

• High-Capacity 2,500kg Load Rating (Per Pair): Heavy 10-leaf stack provides dependable load-bearing support for up to 1,250 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: Integrates into multi-axle equalizer systems to distribute payloads evenly across tandem or triple axles when traveling over uneven terrain.

• 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, bobcat transporters, machinery haulers, and commercial flatbeds.

• Agricultural Implements & Farm Wagons: Heavy-duty suspension for mobile fertilizer tanks, grain carts, field service trailers, and agricultural machinery.

• Horseboxes & Livestock Transporters: Double-eye mounting delivers a smoother, quieter ride that reduces animal stress and controls lateral sway on rural roads.

• Heavy Touring Caravans & Campers: Extended-span suspension engineered to cushion internal caravan cabinetry, electronics, and appliances against prolonged road vibration.

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