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"
Stainless steel hardware
Wind deflection panel
ARB fitting instructions
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.

Warranty, Shipping & Returns

We describe ARB's warranty exactly as ARB publishes it rather than restating or extending it, and it is honored through any ARB-authorized dealer in the US.

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.

The ARB Story
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.

Versatile & Robust Mesh Rack
This ARB mesh roof rack has been outstanding on my 4Runner. The aluminum and fully welded construction make it extremely robust and weather proof. Its also much less prone to failure than many of the other T-slot style racks on the market as there is no assembly of the rack(just 12 bolts mounted to the ARB mounting kit rails). The mesh rack came to me in great condition - powdercoat and welds were all perfect. With a bit of creativity, the mesh floor becomes super versatile. I get loads of comments and questions about this rack. I think it looks super clean!
