Description
The Dirt King Long Travel Suspension System is engineered to dramatically enhance off-road handling while maintaining excellent day-to-day drivability. Up front the system delivers 13” of travel and supports up to a 37” tire offering substantial improvements in articulation and clearance. Designed for both 2WD and 4WD models when paired with extended axle shafts. Compared to the competition we’ve gained several inches of ground clearance by mounting the lower arms in the factory location instead of below it. The system is fully CAD-designed, rigorously tested, and proudly manufactured in the USA.
In the rear the setup provides up to 16” of usable travel when combined with the Dirt King bedcage and Deaver R81 leaf springs. Together the front and rear kits create a balanced, high-performance suspension package that transforms the vehicle’s capability without compromising reliability or everyday usability.

Shocks
For the best performance and to achieve the full amount of travel you must purchase our spec built shocks or have them custom built based on our coil over spec sheet. Our long travel kit is also tabbed to accommodate bypass shocks. The bypass shocks will allow for superior suspension dampening and tunability. To mount the bypasses we offer a weld on bypass shock hoop kit (DK-636710) that can be purchased separately. The bypass shock hoop kit requires welding and modifications to the frame. For extreme off-roading the kit has the ability to accept bump stops along with the coil overs and bypasses. The use of bump stops will alsorequire welding and modifications to the frame.
What's Included
• Long Travel Kit: Enhances off-road performance with an additional 3.5" width per side, supporting 37" tires and increasing suspension travel to 13".
• Long Travel Spec Fox Coilovers: Custom-tuned Fox Spec coilovers to deliver superior performance for both off-road adventures and daily drivability.
• Long Travel Spec Fox Triple Bypasses: The Dirt King spec bypass shocks are custom-designed for GM long travel kits, offering adjustable compression and rebound damping for fine-tuned ride quality, though they produce noise due to internal valving mechanisms.
• Bypass Shock Hoop Kit: This product streamlines the installation of bypass shocks on Dirt King long travel kits or performance lower control arms with pre-fabricated shock hoop components that require no measuring—just weld into place.
• Front Frame Plate Kit: Made from 10-gauge steel, this frame plate kit reinforces the GM 1500 frame rails from the firewall to the coil buckets—ideal for off-road use—and can be paired with a custom crossbar for added strength.
• Bed Cage Spec Fox 16" Triple Bypasses The Dirt King bed cage spec Fox bypass shocks are custom-tuned for optimal performance across varied terrain, offering a smooth yet progressively firmer ride, with easy adjustability.
• Prefab Bed Cage: The Dirt King Prefab Bed Cage offers a high-performance, easy-to-install suspension upgrade with minimal bed intrusion, superior shock placement, and enhanced stability compared to cantilever systems. Comes in satin black.
• Deaver R81 Springs & Hardware: The Deaver R81 Progressive Series springs provide a smooth, performance-driven ride for the GM1500 by using a high-count, flexible leaf stack, and when paired with Dirt King's long travel kit and bed cage, they enable up to 16" of rear suspension travel.
• 2" Wheel Spacers: Forged Alloy's hub-centric wheel spacers are precision-machined from aerospace-grade aluminum and built with heavy-duty steel studs for superior strength, durability, and performance enhancement.
• Long Travel Shackles: The Dirt King long travel shackles allow for additional down travel when paired with long travel leaf springs and are much stronger compared to the factory shackles.
• Leaf Over Shock Mounts: The leaf over shock mounts were designed to be installed with the prefabbed bedcage and long travel leaf springs that mount on top of the axle. This product mounts on top of the leaf springs and held in place by the u-bolts.
• Axle Assemblies (4WD)
• All Necessary Mounting Hardware
• Dirt King Sticker Pack
• Installation Instructions
