The Shimano Custom Spool series consists of shallow replacement spools engineered for maximum casting distance and optimized performance with thin-diameter lines.
Designed for surfcasting specialists and long-distance anglers, these spools are a technical upgrade that enhances line control, casting precision, and efficiency. Featuring Shimano’s advanced AR-C spool lip and a shallow profile, the Custom Spools significantly reduce friction, ensuring smoother, longer, and more accurate casts. Their optimized line management minimizes tangles and improves line lay under pressure, whether using monofilament or braided lines. The reduced capacity also means greater cost efficiency, requiring less line to fill the spool completely.

Compatibility:

Custom Spool 3500A → Ultegra XR, Ultegra XTE/XSE, Speedmaster 14000

Custom Spool 3500B → Aerlex, Beastmaster 14000, Bull’s Eye

Durable, precise, and performance-focused, the Shimano Custom Spools are the ideal upgrade for anglers looking to enhance their casting distance and efficiency in any surfcasting condition.
