Shimano Tranx 400B Baitcasting Reel

The Shimano Tranx 400B is a heavy-duty low-profile baitcasting reel for anglers who throw large baits, pull hard-running fish, and fish confidently in both freshwater and inshore saltwater. Its rigid frame, powerful drag, and roomy spool give you the control to turn demanding fights into fish-at-the-net moments.

Why It Earns a Spot on Your Deck

When a standard bass reel feels outmatched by a big swimbait, deep water, or a strong saltwater run, the Tranx 400B brings the extra backbone you need without giving up the palmable feel of a low-profile reel. It is a practical choice for anglers who want one powerful casting reel that can move between trophy freshwater work and serious inshore duty.

Built for Heavy Work

The CoreSolid Body and HAGANE Body construction help keep the reel rigid under load, while X-Ship supports smooth, efficient gear alignment during long retrieves and hard fights. The Cross Carbon Drag system delivers up to 22 pounds of smooth stopping power on the B models, and the high-capacity spool leaves room for heavier line and longer runs.

When Lighter Reels Start to Feel Small

Big lures, thick line, and powerful fish can expose flex, limited capacity, and inconsistent drag in lighter reels. The Tranx 400B is designed to solve that problem with a compact, ergonomic body that still brings heavy-tackle strength to the cast and the fight.

Power with a Purpose

• Advantages: heavy-duty construction, strong drag performance, high line capacity, smooth retrieve, and a low-profile shape that is comfortable to fish all day.
• Trade-offs: this is a purpose-built power reel, so it is heavier and more specialized than a finesse or light-lure baitcaster. The HGB models trade some maximum drag for a faster retrieve.

The Right Pick If...

• You throw oversized swimbaits, glide baits, jigs, or live bait.
• You need a low-profile reel for tarpon, halibut, sturgeon, big bass, striped bass, or smaller tuna.
• You fish heavy line and want extra capacity for deep water or long runs.
• You prefer the feel of a baitcaster but need more power than a typical bass reel provides.

Best Fishing Techniques

• Big swimbaits and glide baits for trophy largemouth and striped bass.
• Heavy jigging and large lures for tarpon, halibut, and inshore saltwater species.
• Live-bait presentations where strong drag control and line capacity matter.
• Bottom-oriented presentations for sturgeon and other large freshwater fish.
• Heavy iron and large-profile lures for smaller tuna and yellowtail.

Best Conditions

• Freshwater and inshore saltwater environments.
• Heavy current, deeper water, structure, and open water where fish can make long runs.
• Windy sessions and demanding casts with larger, more aerodynamic lures.
• Any trip where durability and control matter more than a featherlight setup.

Tackle Express Tips

• Match the 400 models to a right-hand retrieve and the 401 models to a left-hand retrieve before you spool up.
• Choose the B models for maximum drag, or the HGB models when a faster retrieve helps keep up with moving fish or quickly pick up slack.
• Rinse the reel with fresh water after saltwater use, then let it dry fully before storage.
