Stoltz Industries

<h3>About Stoltz Industries</h3><p>Stoltz Industries has built a reputation as one of the most trusted names in boat trailer roller technology. Manufactured in Marshfield, Wisconsin, every Stoltz product is designed and built in the USA — a commitment that speaks directly to the brand's emphasis on quality control and long-term durability. Whether you're a weekend lake fisherman or a serious offshore boater, Stoltz's engineering-focused approach to trailer components means less time wrestling with equipment and more time on the water.</p><h3>The Stoltz Super Roller Difference</h3><p>At the heart of the Stoltz lineup is their signature <strong>Super Roller</strong> series, crafted from high-performance polyurethane — a material that sets the brand apart from competitors relying on rubber or PVC. Polyurethane rollers resist cuts, absorb shock, and won't leave marks on a boat's hull, making them the preferred choice for boaters who want to protect their investment at every launch and retrieval. While rubber and PVC rollers may carry a lower upfront cost, Stoltz's polyurethane formulation is engineered for a longer service life, ultimately delivering better value over the life of the trailer.</p><p>The full range of Stoltz <a href="/7591-stoltz-industries-non-markingpolyurethane-rollers-200719">Non-Marking/Polyurethane Rollers</a> includes keel roller assemblies, bow stop rollers, V-bow rollers, flat rollers, and bell end caps — covering virtually every position on a boat trailer where contact between the hull and trailer frame occurs. These rollers serve as a critical buffer, shifting load to shock-absorbent surfaces and reducing the friction and wear that can cause cosmetic or structural damage to a boat over time.</p><h3>Trailer Parts &amp; Accessories</h3><p>Beyond individual rollers, Stoltz offers a broader ecosystem of <a href="/7591-stoltz-industries-trailer-parts-accessories-201094">Trailer Parts &amp; Accessories</a> designed to make boat trailering safer and more efficient. From cross-member skid pads to complete roller assembly kits featuring stainless steel shafts and galvanized brackets, the brand covers the full spectrum of what boaters need to keep a trailer performing at its best. These components are engineered to work in concert with Stoltz's roller systems, ensuring consistent fit and function from the winch post to the rear bunks.</p><h3>Rubber Rollers</h3><p>In addition to their flagship polyurethane line, Stoltz also produces a selection of <a href="/200885-rubber-rollers-stoltz-industries-7591">Rubber Rollers</a> for applications where a traditional material is preferred or required. These rollers carry the same attention to dimensional accuracy and durability that defines the Stoltz brand, making them a reliable option for trailer owners seeking compatibility with a wider range of setups.</p><h3>Made in the USA, Built for the Water</h3><p>Stoltz Industries products have earned the trust of boat manufacturers, marine dealers, and DIY trailer builders alike. Their rollers are widely recommended by boat manufacturers as an upgrade over stock trailer components, and they are stocked by marine retailers across the country. For anyone looking to extend the life of a boat trailer while better protecting the hull, Stoltz Industries remains a benchmark brand in the marine trailering industry.</p>
