Installing Fox Shocks on a Super Duty: What You Need to Know
Thinking about upgrading the suspension on your Super Duty? You might want to read this first.
When it comes to aftermarket shocks for Ford trucks, no name is currently bigger than Fox. Mostly because, well, Ford installs them on the Raptor from the factory. And as you might’ve heard, they’re a big part of what makes the Raptor so darn capable off-road. Naturally, Fox is more than happy to sell you the same equipment for your own truck, whether that be an F-150 or Super Duty. But when Ford Truck Enthusiasts member TXSD6.2 was shopping for his own Super Duty, he wasn’t quite sure what parts he needed. Luckily, we’ve got plenty of subject matter experts here in the forums.
“Am I buying the right parts? Seems pretty cut and dry to me, just thought I’d have someone sanity check what I’m buying. 2018 F-250 w/ 2.5″ level kit. 2.5″ lift in the front, rear has been lifted 0 inches. Fox website says: Front shocks w/ 2-3.5″ lift (assuming that means in the front only) would be 985-24-155 x2. Rear shocks w/ 0-1″ lift (again, assuming that means in the rear only) would be 985-24-151 x2.”
Turns out, plenty of folks have already done the same exact job. Including User2017.
“I just put in a 2.5 front lift in my Super Duty a week ago.
Fox 985-24-155 front
985-24-001 front stabilizer
Readylift track bar bracket SKU: 67-2538
Skyjacker 2-in coil springs SKY F520
MOOG K80154 adjustable caster bushings.”
And he seems to have found the perfect combo.
“Night and day difference in the ride. The energy from speed bumps and road ruts is dissipated at the shock level. The harshness of and jolts of the road ruts and speed bumps is greatly reduced!! The Skyjacker coils are heavier (combined 45 lbs) than the stock coils. I haven’t hit the highway long enough to see how much bump steer is reduced rolling empty.
In my opinion, the combination of the upgraded coils and shocks and steering stabilizer is the way to go. I was not comfortable with the idea of putting spacers for my coils or shocks. The truck tracks straight. I have not noticed any push from the steering stabilizer that some others on the forum are experiencing.
The 3.3 left front and 3.7 right front caster adjustment took the loose feeling out of the steering wheel, feels stiffer like day one off the lot.”
SC_Mike chimes in with some helpful pros and cons on both the Fox shocks upgrade and steering stabilizer kit.
“I put a BDS level with Fox Shocks and the steering stabilizer in my Super Duty this past Friday. The overall ride has some positives and negatives after the level.
The Foxes seem to soak up some of the smaller bumps. I also saw an improvement when hitting areas of the concrete freeway when the truck has the up and down shake for long periods of time. If feels like it’s gonna shake your guts out. Also the ride really seems to settle down after 70 mph.
My steering wheel seems to wander a bit when towing. It also feels a little loose. Not much, but I can tell. I think I’m going to have to get airbags now to get a little more rake back. I’m also experiencing more side to side movement when going over larger stuff. The stock shocks seemed more firm in this way. Lastly, I feel like the bump steer and shutter got a little worse with the level.
I was was really hoping for a smoother and more confident ride with the Foxes and the upgraded steering stabilizer, but that’s not quite the case. I’ve read somewhere that you need to put about 500 miles on the new tires to wear off some of the slick stuff from manufacturing. I’m hoping the ride improves in a week or two.”
All of which is pretty darn helpful advice for anyone looking to upgrade the suspension on their Super Duty. But it’s also just scratching the surface. Be sure and check out the entire thread by heading over here. And while you’re there, let us know your own experiences with suspension upgrades!
