Best Bronco Raptor
Rear Suspension Protection:
Shock Guards & Module Guards
Two of the most expensive things to break on a Bronco Raptor live in the same place — the rear suspension. Here are the two new bolt-on kits that keep rocks, roost, and mud from ending your weekend.
Short Answer: What's the Best Way to Protect a Bronco Raptor's Rear Suspension?
Two things. First, the exposed rear shocks and suspension links, which take a constant beating from mud and rock roost thrown by the front tires. Second, the Active Suspension Control Module (ASCM) — the computer that runs your Fox Live Valve shocks — which hangs low on the passenger-side frame rail with its connector fully exposed.
Foutz Motorsports builds a direct-fit solution for each: the Rear Shock Guard Mud Flap Kit ($329.99) and the Active Suspension Control Module Protective Guard ($129.99). Both bolt on, both use factory mounting points, and both are made in-house in Arizona.
The 2022+ Ford Bronco Raptor came from the factory with more suspension travel and more electronic control than any Bronco before it. That's exactly what makes it so good in the desert — and exactly what leaves its rear suspension so vulnerable. Ford routed the hardware where the packaging allowed, not where the rocks aren't.
At Foutz Motorsports we've been building and racing Ford off-road platforms since 1998, and we built the very first Raptor to run the Baja 1000 back in 2009. We don't guess where these trucks break — we've watched it happen, on our own rigs and on customers' rigs. These two kits exist because we kept seeing the same two failures.
The Two Rear Suspension Protection Kits
Rear Shock Guard Mud Flap Kit
Why Do Bronco Raptor Rear Shocks Need a Mud Flap?
Because on the Bronco Raptor, the rear shocks sit out in the open directly behind the front tires. Every rock, every clod of mud, every bit of trail debris your 37" front tires pick up gets fired straight back at the shock bodies, the shafts, and the rear links. That's tire roost, and it does real damage — pitted shock shafts, torn seals, chipped coating, and eventually a leaking shock.
A standard mud flap doesn't solve this. It hangs behind the tire and stops at the sheet metal. The Foutz Rear Shock Guard Mud Flap is 18 inches long and 7 inches wide and is positioned specifically to put material between the front tire and the rear suspension. It's not a styling flap. It's a shield.
Built to Take a Hit, Not Just Look Like It Can
The flap itself is thick, nylon-reinforced rubber. That reinforcement matters: cheap rubber flaps curl back at speed and tear at the mounting holes after a season of hard use. This material stays put and stays flat when you're moving.
The mounting brackets are precision laser-cut, CNC-bent, and MIG-welded in our own shop, then finished in hammer-black powder coat. The bracket bolts to the upper side of the OEM frame using existing hardware — no drilling, no cutting, nothing permanent.
Best Pairing: Foutz Rear Mid Travel Suspension
If you're running our Rear Mid Travel Suspension Kit with 14" travel smooth-body and 3-tube bypass shocks, this flap kit isn't optional in our book — it's the cheapest insurance you can buy on that setup. Those shocks cost multiples of what this kit costs, and a pitted shaft on a bypass shock is not a cheap fix.
For full rear suspension coverage, stack it with the Rear Shock Skid Plate Kit (armors the lower shock shaft) and the Rear Lower Link Frame Skid with HDPE slide. Flap on top, skid underneath — the shock is covered from both directions.
What's In the Box
Sold as a pair. Kit includes (2) pre-assembled mud flap guards, (2) spacer brackets, (4) flange nuts, and all hardware required to bolt onto the frame. Fitment: 2022 and up Ford Bronco Raptor.
Active Suspension Control Module Guard
What Is the Active Suspension Control Module on a Bronco Raptor?
The Active Suspension Control Module — the ASCM — is the brain behind the Bronco Raptor's Fox Live Valve suspension. It reads sensor data and adjusts shock damping in real time, dozens of times per second, so the truck can be comfortable on pavement and composed at speed in the dirt. It's what makes Baja mode and every other drive mode actually work.
Why Is the ASCM So Easy to Damage?
Because of where Ford put it. The module hangs low on the passenger side of the frame near the rear suspension — right in the path of anything the rear tire kicks up and anything you drag over. Worse, the plug connector is the most exposed part of the assembly. It's the first thing a rock finds.
Here's why that matters more than it sounds: when the ASCM is damaged, the Bronco Raptor loses all of its drive modes. Not one. All of them. You go from a $90,000 desert truck to a very heavy Bronco with a dash full of warnings — usually a long way from a dealer. And factory replacement modules are expensive and not always quick to source.
How the Foutz Guard Fixes It
The guard is cut from .125" aluminum, precision laser-cut in-house, CNC bent to shape, and finished in hammer-black powder coat for corrosion resistance. It's shaped to shield the body of the module and the exposed connector — which is the whole point, since covering the module but leaving the plug hanging out solves nothing.
Installation is a direct fit. It bolts to factory mounting points using the existing hardware plus the included threaded standoff studs, which set the correct gap between the guard and the module. No drilling, no modification, no wiring changes. The Fox Live Valve system doesn't know it's there — all factory drive modes, including Baja, are fully preserved.
The $129 Question
A Bronco Raptor Active Suspension Control Module is a dealer-priced electronic component, and replacing one means labor plus downtime plus whatever your trip was worth. This guard is $129.99 and installs in a driveway with hand tools.
That's the entire argument. There isn't a more favorable cost-to-risk ratio anywhere on this truck.

Which One Should You Buy First?
If you can only do one right now, start with the ASCM guard. It's the cheaper kit, it takes less time to install, and it protects against the failure with the worst consequence — losing every drive mode on the truck. Then add the mud flap kit before your next trip.
Running both is the right answer for anyone who wheels the truck hard. Together they're under $460 and they cover the two rear suspension failures we see most often on this platform.
Bronco Raptor Rear Suspension Protection FAQ
Both kits are designed specifically for the 2022 and newer Ford Bronco Raptor. They're built around the Bronco Raptor's frame, rear suspension geometry, and ASCM location, and are not intended for the standard Bronco.
No. Both kits are bolt-on. The mud flap bracket mounts to the upper side of the OEM frame, and the ASCM guard bolts to factory mounting points using the included standoff studs and existing hardware. No drilling, no cutting, nothing permanent.
No. The guard is a purely mechanical shield with no electrical connection. All factory drive modes, including Baja, and the full Fox Live Valve active suspension system continue to operate exactly as they do from the factory.
The Bronco Raptor loses all of its drive modes. The most vulnerable point is the plug connector, which sits exposed on the low passenger side of the frame near the rear suspension. Once that's compromised, the active suspension system can't function and the truck drops out of its selectable modes.
As a pair. The kit includes two pre-assembled mud flap guards, two spacer brackets, four flange nuts, and the hardware to install onto the frame. The ASCM guard is a single passenger-side unit, since that's where the module is mounted.
Pair the mud flap kit with the Rear Shock Skid Plate Kit for lower shock shaft armor, and the Rear Lower Link Frame Skid with HDPE slide for full rear suspension coverage. That combination protects the shock from above with the flap and from below with the skid.
Yes. Both kits are designed and manufactured at Foutz Motorsports in Arizona — laser cut, CNC bent, MIG welded, and powder coated in-house. American made, off-road proven since 1998.
Built from Race-Proven Experience
Foutz Motorsports has been making off-road great since 1998. We built the first Ford Raptor to race the Baja 1000 in 2009, and our founder Greg Foutz has won countless races in production stock trucks. That's not marketing history — it's the reason we know where the Bronco Raptor is weak before most owners find out the hard way.
Every protection kit we make is engineered around the way these trucks are actually used, then cut, bent, welded, and coated in our own shop. If you're not sure which kit fits your build, call us. Our team has more hands-on experience with the Raptor family than anyone else on the planet.
