2021 Ford F-150 Raptor w/37" Tires: Suspension Flex Test and Coil Spring Rear Suspension Walkaround
The 2021 Ford F-150 Raptor just debuted its third generation major redesign, and it includes two major new developments: a unique long-travel off-road focused coil spring rear suspension that’s not shared with any other F-150, and the option of upgrading the standard 35-inch off-road tires to 37-inch off-road tires. The truck in this video is equipped with the 37-inch option, which include bead lock-capable 17 x 8.5-inch wheels and 37x12.50R17 LT BFGoodrich All-Terrain KO2 tires in load range C. Unlike the Bronco Sasquatch and Badlands, which ride on off-road optimized Bilstein shock absorbers, the Raptor rides on Fox Live Valve long travel internal bypass shocks,
With the standard 35-inch tires installed, the Raptor’s front suspension boasts 14 inches of front travel and 15 inches of rear travel. But as is the case with the Bronco Sasquatch upgrade, the Raptor with the optional 37-inch diameter tires has its suspension travel restricted by an inch at both ends. The so-called Raptor 37 has 13 inches of front travel and 14.1 inches of rear travel. But this isn’t necessarily a competitive disadvantage, because the rival Ram 1500 TRX has pretty much the same travel as the Raptor 37: 13 inches of front travel and an even 14 inches of rear travel.
What does this mean for my Flex Index test on the home-made 20-degree RTI ramp? With the same travel and nearly the same wheelbase, one would expect the Raptor to equal the Flex Index score of the Ram 1500 TRX, which was 602 points when I tested it a few months ago. But you can’t accurately predict performance from specs written out on paper, so in this video I’ll be putting the new third-generation 2021 Ford F-150 Raptor with the coveted 37-inch tire option on my RTI ramp to measure its Flex Index score. While we’re there, I’ll pause a minute to take a close look at its all new and unique-to-Raptor link-coil rear suspension in a special version of my Suspension Walkaround series.
Why am I doing this? I geek out over vehicle suspensions, especially ones that are new and unique. I'm a former suspension development engineer that worked for years on truck and SUV suspension development projects for two automakers at their remote desert proving grounds. Later on, I somehow stumbled into auto journalism, and for several years I created a popular photo feature called a Suspension Walkaround for Inside Line, a now-defunct offshoot of Edmunds.com (no relation). Today I have resumed writing these features under the name Suspension Deep Dive for Autoblog. Between the two outlets, over 100 of them have been published. Along the way I managed to grow a good-sized fan base, and one question I often heard was, “When are you going to make video versions?”
I never seemed to have the time, the equipment, or the confidence to get in front of the camera, but I got over that by hosting at least 80 professionally-produced videos over three years on the Edmunds You Tube channel. If you like this, please tell your friends, click subscribe, share links to your favorite forums and social media platforms, give it a like and check out the other videos on my channel, which is simply called Dan Edmunds. You can also type in the channel’s alias: SuspensionTuna. And I take requests. I can't promise that I can get my hands on any car or truck, but the odds are good. And the more views I get, the more horsepower I'll have when requesting cars to examine.

The 2021 Ram 1500 TRX 4x4 pickup is a specially engineered off-road truck that clearly has the Ford F-150 Raptor in its sights. The two do share a basic formula: Fit a long-travel wide track suspension, add sophisticated off-road shocks and 35-inch knobby tires, and finish it off with a powerful engine. On this last point the Ram 1500 TRX does indeed destroy the Raptor because it is fitted with...

    Would love to see the Mo(jave)-chine with the sway bar end links disconeccted. Most of us would (eventually) get some quick disconnect of some rype. Articulation is the key to making the Mo-chine into a rock crawling beast.

    @nastysoda9212 Місяць тому

    there are pros and cons, for me the cons outweighed the pros, and essentially it seemed like bandage toyota came up with for rollover accidents. the KDSS has less clearance due to having the skid plate sit lower. cost of repair is insane for washboard roads or fast offroad driving both left or both right wheels with compress at the same time, like driving on a road, which will make the kdss stiffen up and put extremely ahrd hit into the cab. You just can't go wrong with the original design, especially if you know how to drive and what you're doing.

    I believe its industry standard, any height adjustable suspension the rear must raise before the front, and the front must lower before the rear. You can see this on the ford GT too, although its very quick.

But for the odd person that has it fail on them they'll see a more than $5300 repair bill (checked with multiple toyota dealerships that dont normally have to work on them) for a $4000 factory option. It was difficult to justify the spend on this repair and I opted to tear it all out for a non kdss sway bar setup. Wish i never had it equipped. To each their own though.
