Quick answer: If you actually need a bed that tilts to dump its load, the Dump Box Conversion Kit (Universal Fit) is the only real option here at around $182-$195 — it bolts onto an existing cargo bed and adds the pivot hardware, though it won’t fit an EZGO Marathon or Yamaha G2/G9. Most people searching “golf cart dump bed” actually want a fixed hauling box instead: the MJFX Heavy-Duty Cargo Utility Box (about $486.95, 400-lb capacity, 47”x27”x9”) is the best overall pick for EZGO TXT/RXV, Club Car DS/Precedent, and Yamaha Drive/Drive2/G22 fitments, while the RHOX Steel Utility Box (roughly $410-$525 depending on chassis) covers the widest range of carts, including older EZGO Marathon and Yamaha G2/G9 models the other two don’t.
Here’s the part most buyers miss: “dump bed” gets used loosely across the golf cart accessory market to mean any rear hauling box, but only a box with an actual hinge and lift mechanism dumps its contents like a mini truck bed. The two steel utility boxes below are fixed — you still have to shovel or lift material out by hand — while the conversion kit genuinely tilts. Which one you need depends on whether you’re hauling loose material like mulch and gravel (get the tilt kit) or just want a lockable, weatherproof spot for tools and gear (get a fixed box).

1. MJFX Heavy-Duty Cargo Utility Box — Best Overall
MJFX Heavy-Duty Golf Cart Cargo Utility Box
- Heavy-duty steel modular construction measuring 47"W x 27"D x 9"H, rated for 400 lbs — the highest capacity of the boxes we compared.
- Ready-to-assemble design compatible with Club Car DS (2000+) and Precedent, EZGO TXT/T48 (2001.5+) and RXV, and Yamaha Drive (G29), Drive2, and G22.
- Model-specific mounting brackets are sold separately for about $98 each — confirm your exact chassis needs a bracket before you order.
Keep your cart rolling — get batteries, covers, and accessories in two days with a free 30-day Amazon Prime trial, worth it for a box this size since a damaged-in-shipping steel panel is a lot more annoying to wait a second time for. The 400-lb rating and modular steel build are why this is the default pick, but check the fitment list carefully before you order the bracket kit separately.
2. RHOX Steel Utility Box — Best Broad Fitment
RHOX Steel Utility Cargo Box
- 16-gauge steel construction with a textured powder-coat finish and reinforced panels to resist oil-canning, measuring roughly 30"L x 42"W x 8.25"D.
- The widest official fitment of any box here: EZGO RXV, TXT, and Marathon, Club Car Precedent and DS, and Yamaha Drive2, Drive, G14-G22, G9, and G2 — including older chassis the other two options don't cover.
- Price varies noticeably by chassis-specific SKU and retailer, from around $410 up to $525 for the same core box — worth comparing a couple of listings before buying.
3. Dump Box Conversion Kit (Universal Fit) — Best True Dump/Tilt Function
Dump Box Conversion Kit, Universal Fit
- The only product in this comparison that actually tilts — it bolts onto an existing cargo bed and adds the pivot hardware needed to dump loose material like a mini truck bed, rather than just holding it in a fixed box.
- Includes all mounting hardware, though the manufacturer's own installation notes call for some drilling — budget more install time than the two bolt-on utility boxes above.
- Marketed as a universal fit for most gas and electric carts, but its own listing is explicit that it will not fit an EZGO Marathon or a Yamaha G2/G9 — the opposite fitment gap from the RHOX box above.
How to choose a golf cart dump bed or utility box
- Decide if you actually need it to tilt. If you’re hauling loose material like mulch, gravel, or yard debris, only the dump box conversion kit saves you from unloading by hand. If you’re hauling tools, coolers, or gear you’ll lift out piece by piece anyway, a fixed box is simpler and cheaper to install.
- Check the fitment gap both ways. The RHOX box covers older EZGO Marathon and Yamaha G2/G9 chassis; the dump box conversion kit specifically excludes those same two. Confirm your exact model against both lists before buying either one.
- Match capacity to what you’ll actually load. The MJFX box’s 400-lb rating is the highest here, but any box’s rating still has to fit inside your cart’s overall payload — see our lift kit guide if you’re also raising ride height, since added cargo weight changes suspension behavior more on a lifted cart.
- If you need seating more than hauling, look elsewhere first. A dump bed or utility box replaces or sits on the rear cargo area — if you want to add passengers instead of cargo space, see our rear seat kit guide, since most rear seat kits use the same mounting points.
- Budget for a hitch if you’re also towing. A cargo box handles what fits inside the bed itself; for towing a small utility trailer beyond the box’s capacity, see our trailer hitch guide.
The bottom line
Most owners searching for a “dump bed” actually want a solid, lockable hauling box — the MJFX Heavy-Duty Cargo Utility Box is the best overall pick with the highest rated capacity, and the RHOX Steel Utility Box is the one to get if your cart is an older EZGO Marathon or Yamaha G2/G9 that MJFX’s fitment list doesn’t cover. If you genuinely need the bed to tilt and dump loose material, the Dump Box Conversion Kit is the only one of the three that does it — just confirm your chassis isn’t on its short exclusion list first. Once cargo’s sorted, see our golf cart accessories guide for the other upgrades most owners add during the same refresh, and our trailer hitch guide if you need to tow more than the bed itself can hold.
