HIMARKLIF 2 Pair Heavy Duty Trailer Ramp Springs | 2000 lb Torque Left & Right (RS16933LH/RH)

Overview

Meet HIMARKLIF’s robust trailer ramp springs, engineered to support demanding lifting tasks on trucks and trailers. Each spring is forged from high-quality steel, designed to endure repeated cycling with consistent elasticity. The set features seven coils, 4-inch long ears, and a 1/2-inch steel round bar that fits over a 1.5-inch diameter shaft, making installation straightforward for compatible ramps and gates.

Key Benefits at a Glance

• High torque: Rated up to 2000 lb, enabling smoother raising and lowering of heavier ramps.
• Durable construction: Heavy-duty steel and thermal forging practices promote long service life and resistance to deformation.
• Precise deflection: 90-degree torque deflection supports controlled movement under load.
• Left and right compatibility: Specifically designed to replace RS16933LH and RS16933RH torsion springs for reliable symmetry.

With a focus on real-world use, these springs are built to work as part of a trusted ramp system on trucks and trailers. While they can improve the ease of operation, results depend on the overall ramp design, mounting, and duty cycle.

Fit, Specs, and Compatibility

• Coil count: 7 coils deliver consistent force over many cycles.
• Ears: 4 inches long for robust mounting and leverage.
• Bar and shaft: 1/2-inch steel round bar that fits over a 1.5-inch diameter shaft.
• Torque: Up to 2000 lb, supporting heavier ramp gates.
• Includes: 2 pair of heavy-duty trailer coil springs, with opposite twisting directions for both sides.

These springs are designed as a direct replacement for part numbers RS16933LH and RS16933RH, making them a practical option when a ramp spring shows signs of fatigue or damage. Proper replacement can help maintain ramp function and reduce the risk of sudden gate movement.

Real-World Scenarios

Imagine pulling a loaded trailer gate into position on a mature work truck, then easing it back down with controlled resistance. The 2000 lb torque and 90-degree deflection are intended to provide smoother handling across a range of loads, from construction-site gear to daily dock duties. For fleet operators, having a spare pair on hand can cut downtime and keep ramps operating as intended.

Safety and Maintenance

Regular inspection and timely replacement of worn ramps springs can help minimize uneven loading and potential ramp stress. The packaging clearly notes the importance of using the correct left/right springs to maintain proper balance and safety during use.
