Ford Super C 3″ Suspension Kit with KING 2.5 Remote Reservoir Shocks
Take control of your Ford Super C with the WeldTec Designs 3″ Suspension System featuring KING 2.5 remote reservoir shocks.
Engineered specifically for the weight, size, and driving characteristics of Ford F-550 and F-600 Super C motorhomes, this system is designed to improve ride quality, stability, suspension control, and overall confidence both on and off the highway.
At the center of the system are KING 2.5 remote reservoir shocks with compression adjusters, giving you the ability to fine-tune damping for your specific RV, load, and driving preference.
KING 2.5 Remote Reservoir Shocks
KING 2.5 shocks offer increased oil capacity and improved heat management compared with smaller conventional dampers. The remote reservoirs help maintain consistent shock performance during long drives, rough-road conditions, and repeated suspension movement.
The larger shock body and performance-oriented valving provide the control needed to manage the substantial weight and high center of gravity of a Super C motorhome.
Compression Adjustability
KING compression adjusters allow you to change how firmly the shock resists compression, giving you an additional level of control over how the RV responds to changing road conditions.
Increase compression damping for a firmer, more controlled feel during cornering, braking, highway driving, and heavily loaded conditions.
Reduce compression damping when additional compliance and comfort are desired over rough pavement, expansion joints, and uneven terrain.
Instead of being locked into one fixed shock setting, the KING package gives you the ability to tailor the suspension to how and where you drive.
Complete Suspension System
The WTD 3″ system combines the KING shock package with purpose-built suspension components engineered to work together as one complete system.
- 3″ Suspension Lift
Increased ground clearance, improved approach capability, and room for larger tire combinations. - KING 2.5 Remote Reservoir Shocks
Performance dampers designed for improved heat management, consistent damping, and increased suspension control. - Compression Adjusters
Allows the shock damping to be tuned for comfort, control, load, and driving conditions. - Progressive-Rate Rear Leaf Springs
Designed to better support Super C rear axle loads while improving ride quality and suspension compliance. - Upgraded Front Coil Springs
Provides proper front ride height and additional support for the heavily loaded Super C chassis. - Heavy-Duty Radius Arms
Correct suspension geometry while improving axle control, strength, and overall suspension performance.
Built for a Super C — Not Just an F-550
A completed Super C motorhome behaves very differently from the bare Ford chassis it started with.
The additional weight, higher center of gravity, storage, fuel, water, passengers, towing loads, and motorhome body all place significantly greater demands on the suspension.
The WTD system is engineered around those real-world conditions.
The result is improved:
Ride Quality • Body Control • Stability • Ground Clearance • Suspension Travel • Driver Confidence
Whether you’re crossing the country, navigating rough highways, towing, exploring secondary roads, or pulling into uneven campsites, the WTD KING suspension package gives your Super C the control and capability it needs.
Premium suspension. Proven components. Built to go farther.
