Care information
Care information
To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:
- Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
- Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
- For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
- Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
- Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
- After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
- If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

3,500 lb Axles 25.25" 4-Leaf Double Eye Trailer Springs 1-3/4&...
Product Description:
Built to support heavy loads while smoothing out the rider, the Trailer Supplies 4-leaf double eye spring is a reliable suspension component engineered for 3,500 lb trailer axles. Its four stacked steel leaves flex to absorb road shock and reduce wear and tear on your trailer frame, helping maintain proper axle alignment and ensure a level, controlled ride even over rough surfaces.
Measuring 25-1/4" eye-to-eye with a 1-3/4" width, this leaf spring includes pre-installed 9/16" nylon bushings for quieter operation and easier mounting to your trailer's suspension system. The double eye design allows secure attachment to both the hanger and shackle hardware and works well for a variety of single-axle applications, from utility and camping trailers to cargo and equipment haulers.
Multiple kit options are available as springs only, with U-bolt kits, or with complete hanger kits for full suspension replacement. This flexibility makes it easy to choose the right setup for your maintenance or upgrade needs, whether you're replacing worn springs or building a new trailer suspension.
