Features to know about

Carry Big, Odd-Shaped Loads with Confidence: Large, Flat 51" x 49" Platform

When you’re hauling gear that doesn’t fit standard crossbars—like coolers, tents, or storage boxes—a wide, flat surface makes all the difference. The Rhino-Rack Pioneer Platform gives you a 51" long x 49" wide deck to spread out your load. Its open layout handles everything from camping crates to water gear with extra stability and room to tie down what you need for the trip.

Cut Wind Noise on the Highway: Low-Profile, Aerodynamic Design

Long drives can get tiring when your rack catches wind like a sail. This platform sits low and sleek against the roofline, and its aerodynamic shape helps reduce drag and wind noise. The detachable wind fairing further smooths airflow so you can keep your focus on the road and not the whistling above you.

Mount All Your Accessories in One Place: Integrated Channels for Add-Ons

If you like running lights, awnings, shovels, or even a spare tire carrier, this platform is built for that kind of setup. Integrated channels in both the planks and frame fit various Rhino-Rack accessories (sold separately). You can also add accessory bars (RR33AP – sold separately) to mount kayak carriers or cargo boxes, giving you a single platform that works for every kind of gear.

Built to Handle Off-Road Abuse: Aluminum Frame with Reinforced Nylon Connectors

When the trail gets rough, this rack stays solid. The aluminum frame is powder coated to resist scuffs and corrosion, while reinforced nylon connectors keep everything tight under load. It’s been tested for Australian off-road conditions, so it’s ready for your own adventures without flex or rattle.

Set Up and Go: Complete System with SX Legs and Torque Tool

Getting a secure fit shouldn’t require guesswork. This system comes complete with one platform, four SX legs that clamp to raised side rails, and a torque tool set for proper tightening. The result is a solid mount you can trust on every trip—and easy upkeep when it’s time for maintenance.

Kinda expensive for what you get.



by:

Very easy to assemble and install on existing roof rails.



by:

Great product. Real satisfied with my purchase. Fast shipping and excellent customer service.



by:

Product is solid, the instructions are pretty hard to figure out and Rhino Rack does not offer clear instructions for this specific model on their webpage. Over all etrailer was great to work with the only reason I wouldn’t give 5 stars is lack of clear instructions by platform model.



by:

Looks great especially with the full rails. However there are 2 little things that it was lacking; when you try to log into site to find measurements for the cross bars it is a pain and took longer than the build to find. I would recommend etrailer include the fitting specs with package or at least email a pdf of it. 2nd item- the package came with hole plugs but no instructions what or how they fit into this. I later found out as I installed this that I had to drill 4 holes to accommodate the tool to tighten the sx legs. Over all great product



by:

This Rack fits perfectly on my 2022 Altas; I didn't have to change the rails or add anything extra.
Drove it back and forth from North to South CA with no issues, you will notice some extra noise and some drag even if you are traveling with no luggage, but that's expected.
Overall I'm very pleased with this rack; solid and sturdy and with a very rugged look. Given the weight, it might need some effort to take it off, but nothing too complicated; even one person could do it carefully.



by:

Does not fit the Bronco Sport with a moonroof. Followed their terrible instructions to a T and spoke to Rhino Rack Customer support 3 seperate times before getting accurate underbar measurements that they fail to list on their website. One guy said "raise the factory siderails." Lmao



by:

The roof rack is great and very useful. The assembly is simple but it was difficult to figure out because the instructions were useless. Mounting on my vehicle was difficult. It was a situation of needing to tighten it once it was in place but not having enough access to the face of the bolt to get a tool on it. Now that it’s up, it’s looking good and because it’s not that easy to fasten it back on, it’s going to stay up there.



by:

The instructions on etrailer were way better than the ones that came from rhino. The rack is awesome seems to be well built I would highly recommend it to anybody looking at doing any over-landing or tent roof camping



by:

Very nice rack. It holds well and not too noisy when on the highway. I did drill a couple holes in the rack to hold my roof top tent down. Also like how many accessories are available for the Pioneer Platform Rack.

Loving my new Ford Bronco Sport Badlands model and the Pioneer Platform rack! With the Bronco Sport being so new, locating quality accessories was a bit of a challenge. I was excited to see Rhino Rack had the Pioneer Platform rack system I was looking for to start my build! Vicki at etrailer was super helpful in finding the parts, as listed on the Rhino Rack website, to make up the system. The etrailer site had not been updated to include the compatibility with the Pioneer System yet for the Bronco Sport. The parts were actually in stock and ready to ship! I’m giving the Rhino Rack Pioneer Platform 5 stars for ease of assembly and product quality. Assembly and install took about 3 hours, with several fore/aft adjustment to allow for complete operation and clearance for the Bronco Sports moonroof. This rack is the foundation for the complete “overland” conversion to come!

The ordering process and customer service are the BEST
