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 Overview
This 25.25" double eye, 4-leaf trailer spring is engineered to deliver dependable load support and a smoother ride for utility, boat, cargo, and livestock trailers. Rated at 1,750 lb per spring, it supports 3,500 lb per axle, helping absorb road shock, reduce trailer bounce, and keep proper axle alignment under load.
Constructed from heavy-duty 60Si2Mn manganese spring steel, this leaf spring is heat-treated for strength and finished with a corrosion-resistant coating to ensure long-term durability in demanding towing conditions. The double-eye design provides stable, balanced suspension when used with standard hanger setups, making it an excellent choice for restoring ride height and performance on worn or sagging suspensions.
Designed as a direct OEM replacement for part numbers SW4B, LIB-401-DE, 124903, and PR4B, this spring offers straightforward fitment with common 3,500 lb axle setups. It's available as a single spring or as a pair, with optional U-Bolt kits or complete hanger kits for those looking to replace the entire suspension system at once.
