OSP Dunk 48SP Suspend Lure – Deep-Diving Crankbait for Bream & Estuary Predators
The OSP Dunk 48SP Suspend Lure is a compact, high-performance crankbait engineered for precision strikes in deep structure. Designed by Japan’s legendary lure maker Toshinari Namiki, this 48mm suspending lure has earned its reputation as one of the most effective bream lures on the market, especially in tournament settings across Australia.

With a unique elongated diving lip and tight shimmy action, the Dunk 48SP dives to an impressive 3–4 metres, making it perfect for reaching deep rock walls, oyster racks, pontoons, submerged snags, and other fish-holding structure. Unlike sinking crankbaits, this suspending lure allows anglers to maintain precise control during pauses, keeping the bait in the strike zone longer for more consistent hook-ups.

The flat-sided body enhances water displacement, creating strong vibration even with slow retrieves. Its built-in self-dropping weight transfer system ensures longer, more accurate casts—even in windy conditions. Whether you’re targeting bream, bass, EPs (estuary perch), or trout in freshwater and saltwater systems, the OSP Dunk 48SP delivers the action and depth needed for hard-to-reach fish.
