Whether you’re driving to work, towing your toys or heading out on an adventure, this 4" coil over conversion will provide you with the height needed to fit up to 35" tires and greatly improves the ride attributes. This 100% bolt-on system delivers unmatched quality, durability, and real-world performance you can feel.

Engineered to Perform. Built to Last.

This kit features Desolate Motorsports’ proprietary components, purpose-built to eliminate the compromises of outdated factory suspension geometry:

• Coil Over Conversion Buckets – A complete replacement shock mount allowing for coil over shocks.
• D50 TTB Bulkhead – Correct lifted geometry without the need to modify beams.
• Extended Radius Arms – Increase in caster angle and drive characteristics.
• Front Leaf Spring Mounts – Precision-engineered for optimal geometry and strength.
• Shackle & Hanger System – Designed to improve articulation and ride compliance.
• Custom Deaver Leaf Springs – Designed in collaboration with Deaver Spring for superior ride quality and progressive performance for your Heavy-Duty truck
• Custom King 2.5” Diameter Shocks – Featuring compression adjusters for fine-tuning ride characteristics on-road or off.

Every fabricated component is powder coated in a durable semi-gloss black finish, delivering corrosion resistance and a clean, factory-plus appearance.

Performance You Can Feel

This complete suspension kit is tuned for:

• ✅ Superior ride quality on pavement
• ✅ Mild towing applications
• ✅ Mild to moderate off-road use
• ✅ Increased stability and improved rear-end compliance

Enjoy a smoother, more refined ride whether on pavement or rough trails. Utilizing the same extended radius arms as other Desolate Motorsports suspension kits, both steel and billet arm options provide enhanced performance and drive characteristics over stock short arms. The progressive Deaver leaf springs combined with front and rear King 2.5” diameter shocks and a progressive polyurethane bump stop create a balanced system that soaks up washboard roads, controls body roll, and improves overall truck confidence—whether you're commuting, exploring desert trails, or hauling light loads.
