I’ve had roof racks on every car I’ve owned that wasn’t a convertible. But the Front Runner Outfitters Slimline II Roof Rack Kit is different — it’s based on a platform instead of crossbars, making it more versatile.
The Front Runner Outfitters Slimline II Roof Rail Rack Kit is functionally and visibly different than all the other racks I’ve owned.
They primarily carried bicycles and sometimes duffel bags on an accessory tray mounted to a pair of load-bearing crossbars. They all looked similar and visually tagged my vehicle as a cyclist’s. But not so with the Front Runner Outfitters Slimline II Roof Rail Rack Kit.
Front Runner designed the bike, boat, and other mounts around the load-bearing platform instead of crossbars. This strategy opens up many advantages that make the roof rack system much more versatile and, in my opinion, way better looking.
The Platform Is the Key
The Slimline II platform (MSRP $715) is vertically svelte, standing only 2 inches tall, but the 45.9 x 45.5-inch dimensions delivered the maximum amount of real estate on top of my 2018 Subaru Outback. There wasn’t much roof left uncovered. The lack of crossbars made the surface of the platform a large and uninterrupted load-bearing surface.
And because every component of the roof rack has T-track channels in it, anchoring points were infinite for Front Runner bike mounts and accessories as well as anything else. And the tracks accepted standard M8 threaded mounting hardware that is widely available.
The all-black T6 aluminum platform harkens back to Front Runner’s origins. Initially developed for a 1988 Land Cruiser 70 and 1992 Mercedes G-Wagen, a South African design team flexed their engineering, manufacturing, and off-road racing backgrounds. The aesthetic carried over well, even to my rather mundane-looking Outback.
Front Runner Outfitters Slimline II Roof Rack: Assembly & Mounting
The rack arrived flat-packed and unboxing it created a daunting pile of powder-coated parts and stainless steel fasteners. But once I laid the seven platform slats and perimeter frame pieces on the shop floor, the logic hit me, and it was easy to assemble with the directions.
I also mounted a Front Runner Thru-Axle Bike Carrier and a Fork Mount Bike Carrier while the platform was still in the shop. They directly bolted to the T-slots in the platform slats, so mounting positions were infinite and easily altered.
I attached four custom feet and a wind fairing to the bottom of the platform. I lifted the entire platform (44.9 pounds) plus the two bike mounts to the top of the vehicle without issue.
The pair of bolt holes on each of the four feet lined up with the threaded inserts in the roof used for retractable factory luggage rack crossbars (removed). And there was plenty of adjustment room to center and align the rack as desired.
The entire assembly and installation process took an unhurried 2 hours.
