3-Blade 27" Semi-Elliptical Leaf Spring (560kg Pair Capacity)

The 3-Blade 27" Semi-Elliptical Leaf Spring is a lightweight trailer suspension component engineered to provide compliant shock absorption, dependable axle tracking, and vibration isolation for light utility trailers, luggage trailers, lightweight camping haulers, and general-purpose runabouts. Rated for an axle capacity of 560 kg per pair (280 kg per individual spring assembly), this 3-blade spring stack utilizes an industry-standard 27-inch (~685 mm) mounting span to deliver a smooth, responsive ride calibrated specifically for lighter towing applications.

Manufactured from oil-quenched and tempered high-tensile automotive spring steel, the graduated 3-blade configuration delivers a supple spring rate that eliminates the excessive stiffness and violent rebound hopping common when towing light unladen or partially loaded trailers fitted with over-rated springs. Built in a classic eye-and-slipper layout, the rolled forward eye anchors securely into the front chassis bracket for accurate trailing geometry, while the rear slipper tail slides smoothly inside the rear hanger to allow unrestricted elongation under road compression.

Key Features & Benefits:

• Tuned for Lightweight Axle Applications (560kg Pair Capacity): Calibrated for light utility loads (up to 280 kg per individual spring), providing proper deflection without jarring or bouncing unladen trailers.

• 3-Blade Graduated Leaf Stack: Delivers a flexible, progressive spring rate that smooths out corrugated gravel tracks, potholes, and highway expansion joints to protect lightweight trailer chassis and fragile luggage.

• Industry-Standard 27-Inch Span (~685 mm): Matches standard light commercial hanger spacing and mounting configurations, making it an easy drop-in replacement or fabrication choice.

• Reduces Trailer Hop & Rebound: Eliminates harsh trailer skating and tire skip behind the tow vehicle when towing unladen or lightly packed.

• Quenched & Tempered Spring Alloy Steel: Automotive-grade heat treatment ensures elasticity, fatigue resistance, and long-term retention of arch camber under repeated cyclic loading.

• Standard Eye-to-Slipper Orientation: Front rolled and bushed eye anchors firmly to the forward chassis hanger for positive axle alignment, while the rear slipper tail expands freely inside the slipper channel.

• Cost-Effective & Low-Maintenance: Simple mechanical design with minimal moving components, reducing wear points and simplifying routine chassis inspections.

Ideal Applications:

• Luggage & Camping Trailers: Suspension running gear for compact camping trailers, teardrop campers, and enclosed vacation luggage haulers.

• Light Utility Box Trailers: Ideal for single-axle 5-foot and 6-foot residential garden waste, general cargo, and domestic runabout trailers.

• Small Boat & Canoe/Kayak Trailers: Lightweight suspension setups for small inflatables, dinghies, canoes, and personal watercraft trailers.

• Motorcycle & Quad Bike Trailers: Single-bike haulers and lightweight recreation carriers requiring gentle road damping.
