Winthrop X-Caliber 6 Guide Bushing Set

The Winthrop X-Caliber 6-Guide Bushing Set is engineered for serious offshore anglers and custom rod builders who demand unmatched strength, smooth performance, and long-term reliability in the harshest saltwater environments. Designed and manufactured in the USA, these premium roller guides deliver the perfect balance of durability, reduced friction, and low-maintenance operation — making them one of the most trusted guide systems for big-game trolling rods.

Built from precision-machined, aircraft-grade aluminum, each guide in the X-Caliber series features Winthrop’s signature one-piece flex-frame design, eliminating weld points and maximizing structural integrity. This innovative frame construction allows the guide to flex naturally with the rod blank, reducing stress and increasing sensitivity and shock absorption during long, heavy fights with tuna, marlin, wahoo, and other powerful pelagic species.

The self-lubricating bushing system is the heart of the X-Caliber Bushing Set. Unlike ball-bearing guides, these bushings require almost no maintenance, resist binding under extreme drag loads, and deliver consistent, reliable performance season after season. The rollers and spindles are constructed from 316 marine-grade stainless steel, providing exceptional resistance to corrosion, pitting, and saltwater intrusion — a must for gear exposed to constant offshore use.

This 6-guide set offers generous wind-on leader clearance, enabling smooth passage of knots, swivels, and heavy mono or fluorocarbon leaders without snagging. Whether you’re building a tournament-ready 30-class troll rod or a dedicated 80- to 130-class big-game weapon, the X-Caliber Bushing Set ensures smooth line flow, reduced heat buildup, and maximum pulling power where it counts.
