• 4-link front suspension design that maintains proper axle alignment and articulation, enhancing off-road capability and ride quality.
• High-performance coilover shocks with adjustable damping, allowing fine-tuning for various driving conditions and preferences.
• Heavy-duty rear DLSS (Dual-Rate Long Travel) coilovers designed to handle rough terrains while maintaining a comfortable ride on paved roads.
• Precision-engineered components that support increased load capacity, making this system ideal for towing, hauling, and off-road adventures.
• Corrosion-resistant stainless steel construction ensures longevity and reliable performance in harsh environments.

Construction & Design

The Fabtech K2146DL suspension system features a meticulously designed combination of high-strength materials and innovative engineering. The upper coilover mounts are crafted from 1.75" diameter DOM tubing, providing a sturdy and impact-resistant foundation that spans across the frame for even load distribution. The lower mounts are fabricated from 1/4" steel, offering a solid attachment point to the axle housing that withstands demanding off-road impacts.

The coilover shocks utilize stainless steel piggyback reservoirs, which help dissipate heat and maintain consistent damping performance during extended off-road use. The 4-link configuration preserves proper axle geometry, reducing bind and improving articulation for superior off-road handling. All components are precision TIG-welded and finished to resist corrosion, ensuring durability over years of demanding use.

Performance & Sound

This suspension system significantly enhances your truck's handling, ride comfort, and off-road capability. Expect improved damping response, better impact absorption, and increased load support. The adjustable coilover shocks allow you to tailor the ride to your specific needs, whether for daily driving, towing, or aggressive off-road adventures. The system's design minimizes noise and vibrations, providing a quieter, more comfortable ride compared to factory setups.
