Pair Of 24.25″ 3-Leaf Radius End Trailer Spring WIE-3
Best for single-axle trailers requiring a reliable 1,500 lb capacity across both springs. The 3-leaf design supports up to 750 lbs per spring, delivering a balanced ride and straightforward replacement. The springs fit a standard 24-1/4″ eye-to-hook span with a 1-3/4″ width and include high-strength bushings for durability. Suitable for common light-duty trailers and small utility setups.
- Best for: single-axle trailers that need solid load buffering without added complexity.
- Why chosen: proven 1,500 lb axle capacity with durable bushings to absorb road shock.
- Caution: ensure axle and mounting holes align with the 9/16″ bushing ID for proper fit.
24.25″ 3-Leaf Slipper Trailer Leaf Springs With U-Bolt Kit
This pair of 3-leaf springs delivers a combined 1,500 lb axle capacity and includes a complete U-bolt kit, making it ideal for single-axle trailers that require a full mounting package. The springs are sized for 24-1/4″ center-to-end with a 1-3/4″ width and standard 9/16″ bushing ID, which matches several popular Dexter and similar hubs.
- Best for: single-axle trailers needing an all-in-one mounting solution.
- Why chosen: included U-bolt kit simplifies installation and reduces sourcing steps.
- Caution: verify compatibility with existing mounting plates and bushing sizes before purchase.
Dorman 929-1003 Utility Trailer Leaf Spring
Best for smaller trailers needing a straightforward replacement with eye-to-eye ends and a 1-3/4″ width. This 20-3/8″ length, 3-3/16″ arch, and 3-leaf configuration suits compact utility trailers, offering a reliable upgrade path without overkill.

- Why chosen: simple design with predictable performance for light loads.
- Caution: confirm exact length and arch to ensure a precise fit in constrained trailer frames.
iBroPrat Trailer Shackle Kit
Best for tandem-axle configurations requiring a comprehensive shackle kit. This kit complements 3-1/8″ long shackle straps and nylon bushings to support heavier-duty light trailers. It is a good match when upgrading to more robust leaf spring systems and when mounting hardware is needed in one package.
- Best for: tandem-axle trailers and setups needing extra shackle components.
- Why chosen: broad range of hardware supports more demanding light-duty applications.

Best for trailers needing a higher-capacity leaf spring in a standard eye-to-eye design. The longer 26″ length and 4-1/4″ arch provide increased lift and stiffness for heavier light-duty loads, while maintaining a 1-3/4″ width. Suitable for upgrading existing leaf springs or replacing fatigued components on midsize trailers.
- Best for: trailers facing heavier-than-average loads within a light-duty class.
- Why chosen: higher capacity spring with compatible eye ends for durable performance.
- Caution: confirm mounting clearance due to its longer length and arch height.
Buying Guide: Key Considerations For Light-Duty Trailer Leaf Springs
Choosing the right leaf springs involves matching capacity, fit, and mounting hardware to your trailer. The following questions help buyers compare options:
- What is the axle capacity and how many springs per axle are needed?
- Are the ends eye-to-eye, slipper, or radius, and does the width match the axle?
- Is mounting hardware included (U-bolts, plates, nuts) or will it be purchased separately?
- What is the required arch height and spring length to maintain proper ride height?
- Will this be used on a single-axle or tandem-axle trailer, and what is the typical load?
- Do you need compatible bushings and a specific bushing ID for your setup?
Installation And Fitment Tips
- Verify exact spring length (eye-to-eye or slipper) and the width against your axle model.
- Check bushing IDs to ensure correct fitment with mounting hardware.
- Follow the manufacturer’s instructions for torque on U-bolts to prevent slippage and uneven wear.
- Inspect springs for cracks or fatigue before installation to avoid early failure.

Frequently Asked Questions
- Q: Can I replace just one spring or do I need to replace both sides?
- A: For even load distribution, replace both springs on an axle if you are upgrading capacity or experiencing uneven wear.
- Q: Will a higher capacity spring change the trailer height?
- A: Yes, larger arch or longer springs can alter ride height; verify clearance and adjust as needed.
- Q: Are mounting hardware included?
- A: Some kits include U-bolts and plates; others require separate hardware purchases. Check product details.
- Q: How do I know the right width for my springs?
- A: Measure the axle width and the spring plate, typically 1-3/4″ for common light-duty trailers.
