Frequently Asked Questions (FAQ)
The R 304 is GKA's most widely sold rear box, and it earns that position by fitting almost anything. The mounting set is a universal adjustable U-bracket, so the same box goes onto a Polaris, a CFMOTO, a Yamaha or a BRP without model-specific hardware. The form is a refined take on the original BRP G1 box. That shape has been in production long enough to prove itself, and the changes GKA made are structural: the profile is what makes this one of the more durable boxes in its class rather than just one of the better-looking ones. Sealing is a D-profile rubber gasket — a hollow section that compresses along the whole lid rather than a flat strip that only touches where the lid pulls tight. The shell is first-grade imported high-density plastic. SKU: R 304 Long expeditions and hard use on difficult ground are what the R 304 was built around — the combination of a sealed lid, a strong shell and mounting that holds on any rack. The same qualities suit family trips, where the box mostly has to keep everyone's kit dry and locked while the machine goes wherever it is pointed. It is also the box to consider if you own more than one quad, or expect to change machines: the universal bracket moves with it. Universal, thanks to the adjustable U-bracket set. Confirmed brands include Stels, Hisun, CFMOTO, Cectek, Yamaha, Honda, BRP, Suzuki, Polaris, Kawasaki and Kymco. If your machine is not listed, send us the rear rack dimensions and we will confirm before you order. Model-specific alternatives are in the full range of rear ATV cargo boxes.
