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.

Product Overview

This 3-leaf radius end slipper style trailer lead spring is designed for light-duty trailers equipped with 1,500 lb axles. It provides proper suspension movement and load support to help reduce road shock, trailer bounce and uneven tire wear. 

The spring features a slipped end, which is not interchangeable with double-eye springs. Please confirm your trailer uses a slipper setup before purchasing. 

This spring has a 24.25" free length, measured in a straight line from the center of the front mounting eye to the tip of the radius end (not measured along the curve of the spring).  The spring width is 1-3/4", matching common light-duty axle and hanger configurations. 

Constructed from heat-treated steel, this spring is suitable for replacing worn or sagging original suspension components on utility, boat, and small cargo trailers. 

This product is available as leaf spring only, or matching with a u-bolt kit.
