Quick Answer
These two boxes are not really competing for the same buyer, and pretending otherwise would be dishonest. The KEMIMOTO UTV Rear Cargo Box 69 QT Storage Box 2881193 is a 69QT rear bed box whose listing names Polaris RZR platforms — RZR XP 1000, XP Turbo, XP Turbo S, Turbo S, S 900, 900 and S 1000, in 2-seat or 4-seat form (S3). The StarknightMT UTV Bed Storage Box 6.34 GAL Compatible with Polaris Ranger is a 24L (6.34GAL) box whose listing names 2016-2026 Polaris Ranger / Ranger XP 1000 900 570 500, 2016-2026 General 1000 and Massimo T Boss 550 (S4).
So the first filter is your machine, not your preference. RZR sport-side-by-side owners are pointed at the KEMIMOTO box; Ranger, General and T Boss 550 owners are pointed at the StarknightMT box.
The second filter is volume. 69QT works out to roughly 65 liters, against StarknightMT's stated 24L — close to three times the interior space (S3, S4). If you are hauling recovery gear, spare layers and tools for a full day, that gap matters. If you want a lockable spot for a wallet, phone, first-aid kit and a sandwich, 24L is a different and smaller job.
Both listings tell you to confirm fitment before ordering, and StarknightMT says so explicitly in its first bullet (S4). KEMIMOTO refers buyers to its details page for specific models (S3). Treat that as the real instruction, not boilerplate.

Design & Build Quality
Both boxes are polyethylene, and both listings describe an internal seal. The difference is in how much each seller tells you.
KEMIMOTO specifies injection-molded UV-resistant polyethylene (S3). That UV wording is worth pausing on, because a bed box lives in direct sun every hour the machine is parked outside, and unstabilized plastic chalks and gets brittle. StarknightMT's listing calls its material high-quality PE without a stated UV claim (S4) — which does not mean the plastic lacks UV additives, only that the supplied listing information does not state it.
On sealing, KEMIMOTO describes an integrated waterproof seal aimed at rain and snow (S3); StarknightMT describes a sealed rubber strip inside that the seller says prevents water penetration (S4). Here's the thing: both are seller claims, not third-party ingress-protection ratings. Neither listing states an IP rating, a submersion rating, or a pressure-wash rating in the supplied information. Read them as splash-and-weather protection, not as a dry box you can hose down at point-blank range.
StarknightMT does make one structural claim KEMIMOTO's listing does not: it says its box has enough load-bearing capacity to serve as a chair and footrest (S4). No weight limit is given for that use, so treat it as a design intent rather than a rated figure. On stated materials: KEMIMOTO's listing states UV-resistant injection-molded polyethylene, while StarknightMT's supplied listing information does not address UV resistance either way. That is a difference in what each seller publishes, not evidence that one plastic weathers better than the other.
Features & Functionality
The StarknightMT UTV Bed Storage Box 6.34 GAL Compatible with Polaris Ranger pairs an anti-theft lock with a spring rope that the seller says guards valuables in rough outdoor conditions (S4). The KEMIMOTO UTV Rear Cargo Box 69 QT Storage Box 2881193 is described in its listing as a side by side locker toolbox, and the installation steps say to slide the box into the two rear slots and then install two locks; the supplied listing information does not spell out what those two locks secure, and states no anti-theft rating for them (S3). StarknightMT's listing states no lock standard or security certification in the supplied information, so think of its lock as an opportunistic-theft deterrent at a trailhead — not as a safe.
Installation is tool-free on both. KEMIMOTO's approach is to slide the box into two rear slots on the side-by-side and add the two locks, with the seller putting the whole job under five minutes and requiring no additional tools or hardware (S3). StarknightMT uses three quick mount pegs, also tool-free (S4). A three-peg interface is the sort of thing that either lines up with your bed's existing holes or does not, which circles back to confirming fitment.
One genuinely practical KEMIMOTO detail: the listing says it disassembles easily for drainage and cleaning (S3). If you throw muddy tow straps and wet waders in a box, being able to pull it and rinse it is the difference between a tool box and a science experiment. StarknightMT's supplied bullets do not state a drainage or disassembly feature.
Preferred depends on the job. Want a seat and a compact lockbox: StarknightMT. Want serviceability and a bigger sealed volume: KEMIMOTO.
Performance
Performance in this category comes down to how much your box holds, whether it stays put, and whether the contents stay dry. Only the first is a hard published number.
69QT versus 24L is not a close call on volume (S3, S4). 69 US quarts is about 65 liters, so the KEMIMOTO box is roughly 2.7 times the stated interior volume of the StarknightMT box. Practically, that is the difference between a box that swallows a jack, a tool roll, a med kit and jackets for two, versus one that handles a day's essentials with the lid still closing.
KEMIMOTO also makes a packaging argument: its listing says the design saves space in the rear bed box so you can still fit other bags and coolers (S3). That claim only pays off if the box actually sits where your bed geometry expects it, which is another reason to check the model list.
Neither listing in the supplied information states a maximum load weight, a vibration or shock rating, or a dust-ingress figure. So no honest verdict on rough-trail retention is available here for either box — and anyone telling you otherwise on a spec-only basis is guessing.
Preferred on stated capacity: KEMIMOTO. On anything else in this category: not established by the supplied data.
Price & Value
Pricing on both moves, so check the live figures rather than a number in an article: KEMIMOTO UTV Rear Cargo Box 69 QT Storage Box 2881193 and StarknightMT UTV Bed Storage Box 6.34 GAL Compatible with Polaris Ranger.
What we can say about value without a price is this: the two boxes are sized for different missions, so cost-per-liter is not the right lens anyway. If you run a Ranger, the box whose listing actually names your machine — and that adds a footrest use case on top of storage — is the safer spend, because a box that will not attach to your bed is worth nothing regardless of its capacity (S4). Fitment is the value gate. Everything else is secondary.
Which Should You Buy?
- You ride a Polaris RZR (XP 1000, XP Turbo, XP Turbo S, Turbo S, S 900, 900 or S 1000, 2- or 4-seat). The KEMIMOTO UTV Rear Cargo Box 69 QT Storage Box 2881193 is the one whose listing names your platform (S3). Check Price on Amazon
- You run a Polaris Ranger, Ranger XP 1000/900/570/500 or General 1000 from 2016 onward, or a Massimo T Boss 550. The StarknightMT UTV Bed Storage Box 6.34 GAL Compatible with Polaris Ranger names 2016-2026 Ranger and Ranger XP 1000 900 570 500, 2016-2026 General 1000, and Massimo T Boss 550 (S4). Check Price on Amazon
- You need maximum sealed volume. 69QT against 24L is the widest gap between these two, and it goes to KEMIMOTO (S3, S4).
- You want a box that also works as a seat at camp. Only StarknightMT's listing claims that use, describing it as a chair and footrest (S4).
- You haul wet, muddy or sandy gear. KEMIMOTO's stated easy disassembly for drainage and cleaning is the relevant feature (S3).
- Your machine is not on either fitment list. Buy neither of these until you verify with the seller. Both listings direct buyers to confirm the specific model (S3, S4).
How We Research
This website does not do hands-on testing. For this comparison, we pulled each product's Amazon Creators API verified product record and read every published listing feature bullet for both ASINs, checked on 2026-09-06, then compared the stated capacities, materials, sealing methods, mounting hardware and named vehicle fitment side by side. Where one listing states a fact the other does not — UV resistance, seat use, drainage — we say so rather than assuming the silent listing lacks the feature.
Final Verdict
Honestly, the cleanest answer here is that your UTV picks for you. If it says RZR on the fender, the KEMIMOTO UTV Rear Cargo Box 69 QT Storage Box 2881193 is the box whose listing names that platform, and its 69QT capacity plus stated UV-resistant injection-molded polyethylene and easy disassembly for cleaning make it the stronger all-day hauler on paper (S3). Check Price on Amazon
If it says Ranger, General or T Boss 550, the StarknightMT UTV Bed Storage Box 6.34 GAL Compatible with Polaris Ranger is the one that names your machine, and its 24L lockable volume plus seller-stated chair-and-footrest use suits work days and camp setups more than big recovery loads (S4). Its published year coverage runs 2016-2026 for the Ranger, Ranger XP 1000 900 570 500 and General 1000; the listing names the Massimo T Boss 550 without stating model years, so T Boss owners should confirm their year with the seller (S4).

What neither listing gives us is a load rating, an ingress-protection rating or a warranty term in the supplied information. That is a real gap, and it is why the sharpest advice on this page is about fitment and capacity — the two things both sellers actually publish.
Frequently Asked Questions
Sources & Methodology
Nothing on this page was bolted to a machine, loaded with gear or driven down a trail — this website runs no lab and does no physical testing. What went into it: the Amazon Creators API verified product record for each ASIN and every published listing feature bullet for both boxes, read on 2026-09-06, compared line by line on capacity, material, sealing, locking, mounting method and named vehicle fitment. For UTV cargo boxes that is enough to settle the questions that actually decide a purchase — which machines each seller names, and how much each box holds — while leaving open the things no seller publishes here, such as rated load capacity, ingress-protection class and warranty length.
