Trojan TAPER LEAF SLIPPER SPRING - 600KG PAIR is engineered for demanding trailer service, delivering dependable support for boat loads and everyday hauls. Each spring features a 45mm tapered leaf with a rugged Dacromet coating that stands up to salt, spray, and road grime while maintaining a smooth, controlled ride.

Key specifications at a glance:

• Capacity per pair: 600 kg
• Leaf arrangement: 1 x 45mm tapered leaf
• Overall length: 765–350 mm (eye to center bolt)
• Eye diameter: 1/2 inch
• Camber (arch): 155 mm
• Leaf thickness (excluding locator pin): 17.8 mm
• Coating: Dacromet for corrosion resistance
• Locator pin orientation: locating pin is on the top side as installed; axle sits on top with the pin engaging axle location holes

Why this matters: The tapered design reduces side-to-side movement under load, improving stability during launching and retrieval. The Dacromet coating delivers excellent corrosion resistance in marine environments, extending service life in trailer duty cycles and saltwater exposure. The compact footprint and precise eye size simplify installation on standard trailer axles, while the top-located locating pin ensures repeatable alignment every time you mount or remount the springs.

Ideal use scenarios: replacing worn leaf springs on boat trailers (including bunk and roller setups), trailers that frequently encounter wet, salty conditions, or configurations needing a single-leaf slipper spring with a defined arch. This 600 kg pair is well-suited for mid-sized loads and trailers where ride quality and predictable articulation matter most.

Why Trojan quality stands out: Trojan’s suspension solutions combine tight tolerances with proven materials and marine-grade coatings. The result is a reliable, long-lasting component that maintains alignment under load and reduces maintenance intervals, so your trailer stays ready for the next trip.

Practical tips: confirm that the eye size matches your axle (1/2 inch for this model) and measure your current arch to ensure the camber aligns with your trailer’s ride height. During maintenance, keep contact points clean and inspect the top-pin contact areas regularly to preserve smooth operation. If you’re upgrading, the Trojan TAPER LEAF SLIPPER SPRING - 600KG PAIR offers a strong balance of strength, durability, and ease of installation for boat trailers.
