United States 2025: Top 5 Replacement Wheel Stud Kits for Horse Trailers — Tested, Installer-Approved Picks (Dexter Axle, Reliable Trailer, Princess Auto, Tie Down Engineering, LoadRite) That Balance Safety, Corrosion Resistance, and Installation Ease

Dexter Axle is the OEM market leader for replacement wheel stud kits for horse trailers thanks to precision manufacturing and a reputation for fit and finish that minimizes rework during installation. It typically commands a premium but delivers long-term reliability and compatibility that outperforms budget kits like Reliable Trailer and Princess Auto, making it a strong financial choice for owners who prefer fewer callbacks and resale value retention. Compared with specialty corrosion solutions such as Tie Down Engineering's marine-grade studs, Dexter offers a best-in-class balance of strength and broad application coverage for standard trailer environments.

Reliable Trailer's RT-WSK-916 complete stud kit positions itself as the cost-conscious, full-package option for horse trailer owners who need an immediate, do-it-yourself replacement solution. It typically includes all nuts and washers and offers a lower upfront cost than OEM Dexter kits while providing better value than piecing together parts from different suppliers; however, it may not match the corrosion resistance of Tie Down's marine-grade or LoadRite's galvanized offerings. For fleets and hobbyists who prioritize immediate completeness and affordability, Reliable Trailer is a practical market leader in value.

Princess Auto's heavy-duty trailer wheel stud set is a competitively priced, rugged option popular in the US market for horse trailer repairs where extra tensile strength is desired. It often undercuts OEM pricing while delivering a heavier-duty spec than some economy kits, making it attractive for heavier loads or rough-riding trailers, though it may require additional corrosion protection compared with marine-grade stainless options. Compared with Dexter and Tie Down, Princess Auto delivers strong mechanical performance at a more accessible price point for regional buyers.

Tie Down Engineering's 81070 marine-grade wheel stud kit is the technical leader for corrosion resistance, using stainless materials and finishes designed for coastal or high-moisture horse trailer environments. It is typically the most expensive option on the list but justifies the premium with near-zero maintenance and a much longer service life in salt-exposed conditions compared with galvanized or standard steel kits like LoadRite and Reliable Trailer. For owners who operate near saltwater or who want the lowest lifetime corrosion risk, Tie Down offers unmatched protection and peace of mind.
