Adjustable Roller Guide-On System

Extreme Max Adjustable Roller Guide-Ons are not just for helping you load your boat onto your trailer; they also prevent a variety of loading issues. They make loading faster and safer, prevent you from loading too deeply, ensure your trailer stays in the correct position, and are particularly useful at night. These guide-ons can be used on bunk or roller-style trailers up to 3" wide and 4.25" tall. With a full 24” of adjustable width, a pivot ranging from 90° to 70°, and a height adjustment from 28” to 40”, they can be perfectly adjusted to fit your hull.

The Extreme Max Guide-Ons are zinc-coated and recommended for use in freshwater only. Using them in saltwater or brackish water will damage the finish. A 7" bolt kit is available for trailer frames up to 5.25" tall (Extreme Max 3005.4050), and an 8" bolt kit is available for trailer frames up to 6.25" tall (Extreme Max 3005.4053). Each pair of Adjustable Roller Guide-Ons comes with easy bolt-on installation and fits bunk or roller-style trailer frames up to 3" wide and 4.25" tall.

These guide-ons are specifically designed for larger fishing boats, runabout boats, and crafts over 16'. Their multiple adjustments allow for a perfect fit to your hull. Remember that the size and shape of trailer frames can vary significantly, so it's essential to measure your boat on the trailer before ordering to ensure a proper fit. If you have a taller trailer frame (5.25" and 6.25"), hardware is available to accommodate these sizes; please refer to the extended product description for more information.
