Tie Down Engineering 86205 Galvanized U-Bolt Kit
The Tie Down Engineering 86205 Galvanized U-Bolt Kit emphasizes long-term corrosion protection through robust hot-dip galvanizing, making it a top pick for horse trailers operated in wet or coastal environments. Technically it competes by offering superior rust resistance over plain-plated kits, which can reduce maintenance and replacement frequency compared with cheaper alternatives. Financially it sits mid-range: more costly than the most basic kits but often more economical than repeatedly replacing corroded hardware.

Ultra-Tow Heavy-Duty Spring Mounting Hardware Kit
The Ultra-Tow Heavy-Duty Spring Mounting Hardware Kit is aimed at heavy-use horse trailers and owners who tow frequently over rough terrain, offering high-tensile U-bolts, thicker plates, and hardened nuts for increased clamping and durability. Its technical advantage is a higher load rating and tougher components than standard kits, which justifies a premium price for operators who prioritize longevity and reduced downtime. Compared with the Dexter OEM option, Ultra-Tow leans more toward heavy‑duty retrofit strength rather than factory-perfect fit, making it ideal for upgraded suspensions or heavier loads.
