The narrower aluminum flat rack at 87" x 44", with an Amplimesh mesh floor as standard. Full length for a long roof but 44" wide rather than 49", which suits a narrower vehicle or a setup where you want walk around room beside the rack. At 49 lb shipped it is dramatically lighter than the equivalent steel rack, and that saving goes straight back into payload and a lower centre of gravity.
This listing is the rack only. ARB states plainly that a vehicle mounting kit is required and is sold separately, so a rack ordered on its own cannot be fitted to a roof. ARB builds gutter mount and variable height fitting kits per vehicle; get the mounting kit that suits your truck alongside the rack.
What's Included:
ARB Classic flat roof rack, 87" x 44"

Wind deflection panel

Features
Vehicle Mounting Kit Required ARB states the vehicle mounting kit is required and sold separately, though flat racks use existing ARB roof rack mount kits.
Aluminum, Far Lighter Than Steel Roughly a third of the shipping weight of a comparable steel cage rack. Weight saved on the roof is the weight that matters most.
Amplimesh Mesh Floor As Standard ARB fits alloy flat racks with Amplimesh mesh floors as standard, giving continuous support instead of gaps between bars.
Flat Platform, No Cage No perimeter rail, so oversized loads sit flat and gear can be slid on from the rear.
Uses Existing Roof Rack Mount Kits Interchangeable with any application that takes an existing ARB roof rack of the same dimensions.
Fully Welded Assembly The same strength and robustness as the rest of the ARB roof rack range, in a lighter flat format.

About ARB
ARB started in 1975 when Tony Brown came home from a Cape York trip convinced that the four wheel drives crossing Australia deserved better equipment than anything then on sale. He began hand building roof racks and bull bars in his Melbourne driveway, and the initials of Anthony Ronald Brown ended up on what is now the largest 4x4 accessory manufacturer and distributor in the southern hemisphere. The engineering campus at Kilsyth in Victoria still designs and tests the load carrying, air and recovery equipment the brand is known for, and ARB now runs offices in the USA, Europe and the Middle East with an export network reaching more than 100 countries.
In North America ARB trades as Air Locker Inc. from Auburn, Washington, and backs its products with a published US and Canada warranty program. Prestige Truck is an authorized ARB dealer. Every rack, rail and bracket we ship is genuine US market stock covered by ARB North America's warranty and supported by ARB's own fitting instructions.

This OneARB Classic Flat Roof Rack, 87" x 44" Aluminum with Mesh Floor (4900070M)
How a Melbourne driveway operation building roof racks and bull bars in 1975 grew into the southern hemisphere's largest 4x4 accessory manufacturer.
Filmed by ARB across its own Australian factories and proving grounds, it is worth seven minutes if you want to know who builds the gear before you bolt it to your roof.
Frequently Asked Questions
Straight answers on specs, fit and support
Will this fit my vehicle?
Only with the matching ARB mounting kit, which is sold separately and is the vehicle specific part. ARB states plainly that a vehicle mounting kit is required. Ordering the rack alone leaves you with no way to attach it.
How much can it carry?
ARB builds these racks to support the full rated roof load capacity of the vehicle. That means your vehicle roof rating is the governing number, not a rack figure.
Why the mesh floor?
A fully welded mesh floor stops smaller items falling through and gives continuous support for soft or irregular loads, where spaced cross bars only support items long enough to bridge them.
Do BASE Rack accessories fit it?
No. The BASE Rack uses a dovetail extrusion and is a different system entirely. The Classic range has its own accessories, such as the roof rack jerry can holders.
Does it come with a wind deflector?
Yes, ARB includes a wind deflection panel, which reduces the interior noise a roof rack generates at highway speed.
What is the warranty?
Three years unlimited mileage through ARB North America, honored through authorized dealers like us. Keep your invoice and register with ARB after purchase.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
