Stoltz Industries Rubber Rollers
Stoltz Industries Rubber Rollers for Boat Trailers
When it comes to protecting your boat during transport and making launch-and-retrieve a smooth, effortless operation, few names carry more weight in the marine trailer world than Stoltz Industries. Based in Marshfield, Wisconsin, Stoltz has built its reputation around one core product philosophy: replace the ordinary rubber and PVC rollers that wear out quickly with long-lasting polyurethane alternatives that genuinely perform.
The Rubber Rollers category at Stoltz is anchored by their well-known Super Rollers line — a family of keel rollers, bow stop rollers, and transom rollers engineered specifically for the rigors of trailering on open roads and slippery boat ramps. While they are commonly described as "rubber rollers" in the marine trailer world, Stoltz's products are in fact made from high-grade polyurethane, a material that significantly outlasts conventional rubber while still providing the same hull-friendly cushioning boaters expect.
Why Polyurethane Outperforms Standard Rubber
Traditional rubber boat trailer rollers are prone to cracking, compression deformation, and UV degradation — especially when exposed to sun, salt water, and repeated trailer cycles. Stoltz addresses this directly: their polyurethane compound is formulated to resist the elements, maintain its shape under load, and deliver a longer service life that ultimately makes the higher upfront cost worthwhile. A key benefit is non-marking assurance — Stoltz rollers will not transfer stains or scuff marks onto a boat's hull or gel coat, a critical concern for any boat owner.
Keel Rollers, Bow Rollers, and More
Stoltz's roller lineup covers the full range of contact points on a boat trailer. Their keel roller assemblies are available in multiple lengths — including popular sizes such as 5", 7.5", and 12" — with bore sizes to match common 1/2" and 5/8" trailer shafts. Bow stop rollers, available in both standard and "Ultimate" configurations, use V-shaped or semi-V profiles to cradle the bow and prevent the boat from shifting forward on the winch post. Bell-end assemblies complete the bow roller package, providing a snug, hull-protecting fit. Adding Stoltz keel rollers to a bunk trailer significantly reduces the effort needed to launch and retrieve a boat, and helps shift load away from the carpeted bunks — reducing wear on both the boat and the trailer.
Designed and Made in the USA
All Stoltz products are designed and manufactured in Marshfield, Wisconsin, USA — a point of pride for a brand that has earned trust among boat trailer manufacturers, dealers, and weekend boaters alike. Their durability in harsh conditions is well documented; the polyurethane compound holds up even when submerged in brackish or salt water over extended periods, making Stoltz rollers a smart choice for both fresh and saltwater boating environments.
Whether you're upgrading an older bunk trailer, replacing worn-out rollers, or outfitting a new rig from scratch, Stoltz Industries rubber rollers provide a proven, long-lasting solution built for real-world marine use.
