Boat Trailer 4″ Jet Ski Bow Roller – Black Rubber, 14mm Bore, 85 Duro (SKU: JSBBK100X14)

4″ Jet Ski Bow Roller – Built for Precision Launching

The JSBBK100X14 is a 4-inch black rubber bow roller designed specifically for Jet Skis, PWC (Personal Watercraft), and small watercraft trailers. Its compact shape and 14mm bore offer a snug fit for narrow shafts, ideal for light-duty marine setups where precision matters.

Made from tough, non-marking 85 Duro black rubber, this roller ensures smooth bow guidance during launch and retrieval, while cushioning impact at the trailer’s winch post. The hourglass design (approx. 70/55mm diameter) gently cradles the watercraft bow, reducing side shift and hull stress.
