Ford Super C 3″ Suspension Kit with FOX 2.5 Remote Reservoir Shocks
Transform the ride, control, and capability of your Ford Super C with the WeldTec Designs 3″ Suspension System. Designed specifically for the weight and driving characteristics of the Ford F-550/F-600 Super C platform, this system is built to deliver a substantial improvement in ride quality, suspension control, ground clearance, and overall confidence behind the wheel.
At the heart of the system are FOX 2.5 remote reservoir shocks with Dual Speed Compression (DSC) adjusters, giving you independent high-speed and low-speed compression adjustment. This allows the suspension to be tuned for everything from expansion joints, rough highways, and body movement to larger impacts, washboard roads, and uneven terrain.
The system combines premium dampers with purpose-built suspension components engineered to work together as a complete package.
Kit Features
3″ Suspension Lift
Increases ground clearance and creates room for larger tire combinations while maintaining proper suspension geometry and drivability.
FOX 2.5 Remote Reservoir Shocks
Large-body performance shocks provide increased oil capacity, improved heat management, and consistent damping under demanding conditions.
Dual Speed Compression Adjusters
Independently adjustable high-speed and low-speed compression damping allows you to fine-tune ride comfort, body control, and impact absorption for your RV and driving style.
Progressive-Rate Rear Leaf Springs
Designed to better manage the substantial rear weight of a Super C while providing a smoother, more controlled ride than traditional heavily sprung factory configurations.
Upgraded Front Coil Springs
Provides the additional ride height and spring control required for the Super C chassis while improving front suspension support and handling.
Heavy-Duty Radius Arms
Correct suspension geometry while improving axle control, stability, articulation, and strength.
Built for the Way a Super C Is Actually Driven
A Super C RV is not an empty F-550 or F-600 chassis. Once the motorhome body, storage, water, fuel, passengers, and equipment are added, the suspension is operating under significantly different conditions.
The WTD 3″ Suspension System is designed around those real-world loads.
The result is:
Better Ride Quality • More Ground Clearance • Improved Steering and Body Control • Reduced Harshness • Increased Stability • Adventure-Ready Stance
Whether you’re putting thousands of miles on the interstate, navigating broken pavement, pulling into uneven campsites, or traveling farther off the pavement, the WeldTec Designs Super C suspension system gives your RV the suspension performance it should have had from the factory.
More control. More capability. More confidence.

Why DSC Matters
FOX Dual Speed Compression (DSC) adjusters give you independent control over both low-speed and high-speed compression damping, allowing the suspension to be tuned specifically for the weight, handling characteristics, and driving conditions of your Ford Super C.
And importantly, high-speed and low-speed do not refer to vehicle speed. They refer to how quickly the shock shaft is moving.
Low-Speed Compression Adjustment controls slower suspension movements such as body roll, weight transfer, braking dive, cornering, and large chassis movements. Increasing low-speed compression can make a heavily loaded Super C feel more planted, controlled, and predictable without simply making the entire suspension excessively stiff.
High-Speed Compression Adjustment controls faster shock movements caused by potholes, bridge joints, broken pavement, washboard roads, sharp bumps, and sudden impacts. This adjustment lets you control how the suspension reacts to those harder hits while maintaining ride comfort and suspension travel.
Why This Matters on a Super C
A Ford F-550 or F-600 Super C carries significantly more weight and has a much higher center of gravity than a standard pickup. The suspension has to control thousands of pounds of motorhome while still absorbing road imperfections and maintaining driver confidence.
A conventional shock gives you one fixed compromise.
FOX DSC gives you the ability to tune the suspension instead of accepting that compromise.
That means you can dial in:
Better body control
Reduced sway and excessive chassis movement
Improved braking and cornering stability
Better control over large impacts
A smoother ride over broken pavement
More confidence when the RV is fully loaded
Suspension tuning based on your specific RV, load, and driving preference
Whether you’re spending long days on the highway, dealing with rough secondary roads, or traveling beyond the pavement, DSC allows the shock package to be adjusted around how your Super C actually drives.
More adjustability. More control. Better ride quality.
