Suspension Upgrade Package for Ford E-Series with QuadVan 4×4 Conversion
Take your Ford E-Series QuadVan 4×4 conversion to the next level with a suspension system built for comfort, control, and real-world travel. This upgrade package is engineered to improve ride quality on and off the highway, increase stability, and give you the confidence to explore rougher terrain without sacrificing drivability.
Up front, the system features radius arms with adjustable caster, allowing precise alignment to improve tracking, steering feel, and straight-line stability. New coil springs paired with Fox 2.0 shocks deliver a smoother ride, better bump absorption, and improved control in challenging road conditions.
In the rear, progressive leaf springs replace the factory blocks used in many QuadVan 4×4 builds. The WTD progressive spring design eliminates the need for lift blocks, improving rear suspension geometry, increasing strength, and reducing axle wrap. Paired with Fox 2.0 rear shocks, this setup provides consistent damping, reduced sway, and better handling across varying road surfaces.
This suspension package is designed specifically for QuadVan 4×4 converted Ford E-Series vans and RVs, offering a noticeable improvement in comfort, stability, and overall drivability. Whether you’re crossing mountain passes, navigating rough campsites, or spending long hours behind the wheel, this system helps your vehicle feel more predictable, controlled, and enjoyable to drive.
