Boat Trailer Guides, Adjustable Roller Guide-Ons, 2 Pack

Boat trailer guide-ons with smooth rollers help center your V-hull fast, reducing scuffs and misalignment during loading and transport. This 2-piece, height-adjustable set uses rounded guide poles and roller-style guidance to direct small to mid-size boats onto the trailer with less correction at the ramp. Heavy-duty steel with a galvanized coating is built for freshwater use, while the included high-strength hardware installs securely on common trailer frame sizes.

Dial in your trailer alignment and make solo or low-visibility loading easier. The thickened steel build resists bending from bumps during loading, and the galvanized finish supports regular use in freshwater conditions. With two mounting methods, you can match larger or smaller trailer beams without guesswork, then fine-tune width for a secure, centered ride. Ideal for V-hull boats and many small to mid-size vessels—grab yours today and simplify every launch and retrieval.
