Shimano Tranx B Baitcast Reel

Shimano Tranx 300B & 400B Low Profile Baitcast Reels

The Shimano Tranx B series represents a complete redesign of one of the most trusted heavy-duty baitcasters on the market, transforming the Tranx from a proven workhorse into a true thoroughbred.

Tranx 300B

The Tranx 300B is built to dominate demanding freshwater and saltwater applications. Featuring CoreSolid construction combined with a HAGANE Body, the frame, side plate, and level wind guard form a single ultra-rigid unit that eliminates flex under load. This delivers exceptional cranking power and control when fishing large swimbaits, heavy soft plastics, or working finesse presentations in tough conditions.

The SVS Infinity MD Tune braking system provides accurate, effortless casting control—even in wind—while X-Ship and Micromodule gearing ensure smooth power transfer and precise lure control. X-Protect sealing keeps water out, and the strong drag system gives the confidence needed to stop serious fish in their tracks.

Tranx 400B

The Tranx 400B takes things even further, purpose-built for anglers throwing big baits at the hardest-fighting fish that swim. Designed for trophy hunting, this reel delivers flex-free cranking under extreme loads, making it ideal for large swimbaits, heavy jigs, and offshore or river monsters.

With SVS Infinity MD Tune braking, casting heavy lures is controlled and predictable. Cross Carbon Drag provides smooth, reliable stopping power, while S3D Spool technology reduces vibration for ultra-smooth retrieves during long sessions on the water. Equally at home in salt or freshwater, the Tranx 400B is a serious tool for serious anglers.
