Shimano expands Stella line with 25000 SW D for big tuna

Shimano North America introduced the Stella 25000 SW D on January 9, 2026, expanding its high-end Stella saltwater spinning reel family with a very large 25000 size aimed squarely at offshore big-game anglers. The new size is built for bluefin, yellowfin and other heavy pelagics that demand maximum line capacity and sustained cranking power during long, fast runs.

At the heart of the update are drivetrain and drag upgrades designed to spread load, cut friction and hold steady under marathon battles. INFINITYXROSS gears improve load distribution across the gear train, while INFINITYDRIVE reduces friction for smoother power transfer. SILENTDRIVE is carried across the lineup to quiet internal operation and reduce start-up friction for smoother hooksets and steady pressure. For the larger sizes, Shimano pairs an XXTOUGH Drag system with a HEATSINK Drag to maintain drag consistency when the reel heats up during protracted fights.

Durability and saltwater sealing also get attention. Shimano highlights upgraded seals branded X PROTECT and X SHIELD to guard internals in harsh offshore environments and extend service intervals for anglers running big tackle in corrosive conditions. Those features matter on long days offshore where spray, slop and deck wash are constant and reliability is measured in fish landed, not just on-paper specs.

Shimano positions the Stella 25000 SW D as a tool for anglers pairing large pluggers and heavy spinning tackle to chase giant tuna and GTs. The 25000 size gives the line capacity needed for long runs and heavy leaders, while the drag and heat-management upgrades aim to keep pressure steady through repeated surges. For captains and private-boat anglers planning multi-hour battles on bluewater trips, that translates into more control and less thermal fade when fighting big tuna.

Practical next steps: check spool capacity and line recommendations at dealers and prep outfit choices around heavy braid and big plugs; match rod backbone and terminal tackle to the increased cranking power the 25000 delivers.

This release tightens the gap between spinning and conventional options for big tuna work, giving anglers an oversized spinning reel built to handle the heat and the horsepower of modern pelagic fishing. Expect to see the Stella 25000 SW D show up on charter decks and tournament boats where sustained drag performance can make the difference between a landed trophy and a lost fish.
