The YakAttack ShortStak Upgrade Kit replaces the lid of your BlackPak Pro with a stackable second-tier storage compartment — giving you a quick-access layer for go-to gear without sacrificing what's already packed below. At roughly 40% the height of the BlackPak Pro, it adds meaningful space without bulk.
Note: This is not a standalone box. Requires a 16x16 BlackPak Pro (not included).
Why Add a ShortStak?
Modern fishing kayaks sit high off the water, making it awkward to dig into the bottom of a fully loaded BlackPak. The ShortStak puts your most-reached-for items — terminal tackle, tools, electronics accessories — at the top and within easy reach. It's also ideal for anglers running batteries, LiveScope black boxes, or excess cables inside their BlackPak who want to reclaim that lost storage space.
Construction
Injection-molded from UV-stabilized polymers with a ribbed panel structure for exceptional rigidity and minimal weight. Interlocking tongue-and-groove GridLoc panels press together securely during assembly and are fastened with included stainless steel screws. The bottom edge of the ShortStak side panels is angled to match the BlackPak Pro opening geometry for the same water-shedding fit as the original lid.
GridLoc Mounting Platform
Every panel features the same GridLoc 2D mounting platform as the BlackPak Pro, with molded screw bosses for attaching accessories inside and out — including GridLoc MightyMounts, MightyMount XL, Through Hull Wiring Kits, TracPaks, and more.
