ICON Vehicle Dynamics K73004A Stage 4 Suspension System 1-2.5" Lift Kit with Delta Joint

The ICON Vehicle Dynamics K73004A Stage 4 Suspension System is engineered to dramatically enhance on-road and off-road performance for 2014-2018 GM Silverado and Sierra 1500 trucks. This complete suspension system increases wheel travel and damping ability while maintaining factory towing capacity, delivering exceptional vehicle control and ride quality across all terrain types.

Key Features:

• Height adjustable from 1-2.5 inches of lift over stock for aggressive wheel and tire fitment
• Vehicle-specific tuned 2.5" remote reservoir coilover shocks with ICON-engineered Eibach coil springs
• 2.5" aluminum series piggyback rear shocks with remote reservoirs for superior heat dissipation
• Upper control arms featuring ICON's patented Delta Joint technology for enhanced durability and articulation
• 6061 aircraft-grade aluminum CNC machined components for strength and weight reduction
• Corrosion-resistant CAD plated coilover shock bodies with 7/8" hardened shafts
• Compatible with both 2WD and 4WD models

Delta Joint Technology:

ICON's exclusive Delta Joint combines the durability of a heavy-duty ball joint with the performance characteristics of a traditional uniball. The zinc-plated housing provides corrosion resistance, while a robust grease seal protects against contamination. The metal-on-metal construction with greaseable design ensures long-term, noise-free operation with greater angularity than conventional ball joints and superior weather protection compared to standard uniballs.

Remote Reservoir Advantage:

Front and rear remote reservoirs increase oil capacity and cooling surface area, maintaining consistent damping performance during extended off-road use by keeping shock temperatures in the optimal operating range. This ensures the suspension performs at its peak whether you're towing on the highway or tackling challenging off-road terrain.

The Stage 4 system represents the ultimate performance upgrade for GM 1500 owners seeking maximum capability enhancement without compromising daily drivability or towing performance.
