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

The Heavy-Duty 8-Blade 27" Double-Eye Semi-Elliptical Leaf Spring is a commercial-grade trailer suspension component engineered to provide heavy payload support, lateral axle stability, and controlled shock damping for commercial transport trailers, equipment haulers, touring caravans, horseboxes, and livestock transporters. Rated for a combined load capacity of 1,500 kg per pair, this 8-blade spring stack is built in a double-eye configuration across a standard 27-inch (~685 mm) eye-to-eye span, delivering positive axle location and predictable tracking across high-speed highway routes, unpaved gravel roads, and demanding industrial worksites.

Unlike single-eye slipper springs that rest freely inside an open rear chassis bracket, the double-eye design incorporates rolled and bushed eyes at both ends of the main leaf. This dual-eye setup links directly to a fixed front hanger and a rear pivoting shackle link (or rocker beam in tandem-axle setups). By capturing both ends of the spring assembly, it eliminates axle wandering, controls fore-and-aft movement during heavy braking, and provides quiet, rattle-free articulation under peak loading conditions.

Key Features & Benefits:

• Dual-Bushed Double-Eye Configuration: Rolled spring eyes at both ends secure the spring firmly between a fixed front hanger and a pivoting rear shackle link, providing positive axle location and eliminating the slap and chatter common to slipper-style springs.

• 1,500kg Combined Load Rating (Per Pair): Heavy-duty 8-leaf stack supports up to 1,500 kg per axle set (750 kg per individual spring assembly), making it ideal for braked commercial haulers and heavy touring chassis.

• Controlled Axle Alignment Under Braking: Double-eye mounting restrains the axle securely against fore-and-aft deflection, preventing axle twist and tire scrubbing during hard braking maneuvers.

• 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 Spring Steel Construction: Manufactured from oil-quenched and tempered automotive-grade spring steel to resist leaf sagging, metal fatigue, and permanent set under cyclic loading.

• Standard 27-Inch Eye-to-Eye Profile: Built to industry-standard 27" eye-to-eye dimensions for drop-in replacement on existing chassis mounts or straightforward integration into new builds.

• High Roll & Sway Resistance: Multi-leaf architecture provides strong lateral rigidity to resist chassis roll, trailer sway, and load shifts during cornering or in heavy crosswinds.

Ideal Applications:

• Commercial & Plant Trailers: Heavy-duty suspension for single- and tandem-axle plant trailers, bobcat transporters, flatbed haulers, and box trailers.

• Caravans & Expedition Campers: Stable, rattle-free suspension for touring caravans, off-road overland trailers, and heavy camper rigs.

• Horseboxes & Livestock Transporters: Exterior suspension built to support dynamic animal loads while keeping chassis roll and lateral sway controlled during transit.

• Utility & Cargo Trailers: Reliable replacement or OEM suspension for tandem-axle goods trailers and trade contractor haulers.

• Agricultural Implements & Farm Trailers: Chassis suspension for tractor-drawn machinery, bulk produce carts, and mobile generator platforms.
