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:

Achieving the perfect preload on your trailer bearings won't mean much if your spindle nut backs off on the highway. This premium 1" spindle tang washer provides a foolproof, hardware-based lock to keep your castle nut exactly where you set it during service.

Designed for axles featuring 1" D-shaped spindles, the flat inner edge slips over the spindle matching profile to prevent the washer itself from spinning. Once you torque down your castle nut and back it off to your preferred bearing play, you simply bend one of the outer tabs directly into an open slot on the nut. This tab-locking setup completely eliminates the need for messy cotter pins, making it much cleaner to service on popular EZ Lube hub configurations.

Stamped from high-durability 1/32" steel, it resists shearing and crushing under constant wheel-end vibration. It's a low-tolerance, commercial-grade safety part essential for any axle rebuild or bearing repack.
