ICON Vehicle Dynamics 78724 2.5 VS Rear Shock System with Tubular Upper Control Arms 2011-19 GM 2500/3500HD

The ICON Vehicle Dynamics 78724 is a complete suspension system designed specifically for 2011-2019 GM 2500HD and 3500HD trucks with 0-2" lift applications. This comprehensive kit combines ICON's patented Delta Joint tubular upper control arms with Vehicle Specific 2.5 Series rear shock absorbers, delivering exceptional off-road performance and superior on-road ride quality.

Delta Joint Tubular Upper Control Arms:

The included upper control arms are constructed from CNC-bent 1026 DOM steel tubing with a durable semi-gloss black powder coat finish for maximum strength and corrosion resistance. Engineered with built-in caster correction, these arms provide optimal alignment specifications and confidence-inspiring handling. When paired with the included 2.5 Series shocks, these control arms unlock nearly 50% more wheel travel compared to stock components, dramatically improving suspension performance and ride quality.

ICON's Patented Delta Joint Technology:

The Delta Joint is a revolutionary heavy-duty high-angle ball joint that combines the durability of a traditional ball joint with the performance characteristics of a uniball. Unlike standard uniballs that are exposed to harsh elements, the Delta Joint features a zinc-plated housing and tough grease seal that keeps contaminants out. The metal-on-metal construction and greaseable design ensure longevity and noise-free operation, while providing superior angularity beyond typical ball joints and better durability than exposed uniballs.

Vehicle Specific 2.5 Series Remote Reservoir Shocks:

• Nitrogen-charged monotube design with remote reservoir for superior heat dissipation
• 7/8" diameter induction-hardened, chrome-plated shock shaft for exceptional durability
• Premium grade 5WT shock oil ensures consistent damping across a wide temperature range
• PTFE-lined spherical bearings with application-specific mounting hardware
• 6061-billet aluminum manifold creates an internal Bump Zone with 20% additional damping force to prevent harsh bottom-outs
• 100% rebuildable and 100% revalveable design
• Configured specifically for 2011-2019 GM HD applications in both length and damping tune

This system is sold as a complete package to ensure full compatibility and optimal performance. The combination of advanced upper control arms and application-tuned shock absorbers transforms your GM HD truck's suspension, providing the confidence and capability to tackle demanding off-road terrain while maintaining excellent street manners.
