Heavy-Duty 3-Blade 27" Dacromet-Treated Semi-Elliptical Leaf Spring (560kg Pair Capacity)

The Heavy-Duty 3-Blade 27" Dacromet-Treated Semi-Elliptical Leaf Spring is a high-performance suspension component engineered to deliver smooth load dampening, responsive ride dynamics, and advanced corrosion defense for lightweight utility trailers, luggage haulers, camping trailers, and marine boat trailers. Rated for a combined load capacity of 560 kg per pair, this 3-blade spring assembly provides dependable support for lighter axle applications, ensuring compliant shock absorption that minimizes road bounce when running empty or lightly loaded while maintaining firm, stable roll control at highway speeds.

Engineered specifically for demanding outdoor and coastal environments, every leaf in the stack is individually treated with a high-performance Dacromet (zinc-aluminum flake) anti-corrosion coating. Unlike raw steel or basic painted leaf springs that quickly develop inter-leaf pack rust, bind up, and seize from wet weather or marine exposure, Dacromet surface protection provides superior barrier, galvanic, and passivating defense against rust and road grime without causing hydrogen embrittlement. Featuring an eye-and-slipper configuration built to a standard 27-inch (~685 mm) length, this spring guarantees straightforward installation into standard chassis hanger brackets.

Key Features & Benefits:

• Compliant 3-Blade Suspension Architecture: Three-leaf spring profile delivers an optimal spring rate for light-duty towing, smoothing out high-frequency road vibrations and preventing excessive bouncing on empty trailers.

• 560kg Axle Load Capacity (Pair): Calibrated for light utility hauling, supporting up to 560 kg per axle set (280 kg per individual spring unit).

• Advanced Dacromet Anti-Corrosion Treatment: Specialized inorganic zinc/aluminum flake surface coating shields each leaf against salt spray, marine slipway washdowns, standing rainwater, and road grime.

• Prevents Inter-Leaf Pack Seizure: Non-electrolytic protective coating prevents rust bridging and contact seizure between leaves, ensuring smooth, friction-free flex throughout the suspension cycle.

• No Hydrogen Embrittlement: Applied without high-acid pickling or electroplating stresses, preserving the core tensile strength, fatigue life, and flexibility of the spring steel.

• Standard 27-Inch Profile: Built to industry-standard 27" mounting dimensions, allowing quick, drop-in replacement or direct fitment into existing commercial spring hangers.

• Clear Directional Fitment: Standard front eye mounting facilitates correct chassis alignment and reliable trailing-arm suspension geometry.

Ideal Applications:

• Boat & Marine Trailers: High-performance suspension for light marine craft, jet skis, and inflatable boat trailers frequently submerged in coastal or freshwater launch slipways.

• Light Commercial & Luggage Trailers: Everyday suspension for town utility haulers, single-axle luggage trailers, and camping trailers.

• Teardrop Campers & Bush Trailers: Compliant ride quality engineered to protect delicate camping gear and lightweight trailer bodywork from road shock.

• Agricultural Carts & Service Skids: Reliable suspension for light farm carts, mobile generator skids, and agricultural transfer trailers.
