Shimano Tranx 400B Baitcast Reel

The Shimano Tranx 400B is built to throw big baits at brutal fish — barra, cod, murray cod, mulloway, kingfish and saltwater brutes alike. This latest evolution of the legendary Tranx platform delivers next-level cranking power, casting control and durability for anglers who push their gear to the limit.

Purpose-built for heavy-duty applications in both freshwater and saltwater, the Tranx 400B combines Shimano’s CoreSolid design concept with HAGANE Body construction for maximum rigidity and zero flex under load. When you’re grinding oversized swimbaits or pulling fish away from structure, this reel stays solid and connected.

SVS Infinity MD Tune braking provides precise, external adjustment for heavy bait casting control, while X-Ship gear support enhances durability and maintains smooth alignment under extreme pressure. Cross Carbon Drag ensures powerful, consistent drag performance, and the S3D Spool design reduces vibration for ultra-smooth casting and retrieves.

Whether you’re throwing glidebaits for trophy cod, swimbaits for barra or heavy plastics offshore, the Shimano Tranx 400B is engineered to tame the biggest predators that swim.
