Buyer’s Guide: What to Consider

When buying trailer ramp assist springs, consider shaft diameter, torque rating, and compatibility with your trailer’s gate size. These factors ensure safe and easy operation.

• Shaft Diameter: Ensure the assist spring fits your trailer's shaft diameter (commonly 1.5 or 2 inches). A proper fit is crucial for safety and function.
• Torque Rating: Look for springs with 2000 lb torque for heavy ramps. Higher torque means less effort when lifting, but ensure it matches your ramp weight.
• System Type: Coil vs. Lift Assist: Decide between a direct replacement kit (coil springs for shaft) or a lift assist system (cables for side rails). Choose based on your trailer design.
• Material Quality: Steel alloy or forged springs offer better durability and resistance to deformation and corrosion, especially in outdoor environments.
• Left & Right Sides Included: Some kits include both left and right sides, saving you time and ensuring balanced support. Check the package contents before purchase.

Conclusion

Choosing the right trailer ramp assist springs can transform how you use your trailer, reducing strain and speeding up loading. Whether you need a direct coil spring replacement or a full lift assist system, focusing on shaft size and torque ensures a perfect match.

For heavy-duty reliability, the TRUCFUSION or Basysion coil springs are excellent picks. If your trailer has side rails, the JY PERFORMANCE kit offers great value. The NAZOU system is a solid budget-friendly alternative with adjustable tension. Pick the one that fits your trailer’s design and your lifting needs.
