ICON Vehicle Dynamics K77102 0-2" Lift Stage 3 Suspension System GM 2500HD 3500HD 2001-2010

The ICON Vehicle Dynamics K77102 is a complete Stage 3 suspension system engineered specifically for the 2001–2010 GM 2500HD and 3500HD platform. These heavy-duty trucks demand significant shock damping to manage the massive spring rate of the factory torsion bar system, and ICON has answered with a purpose-built solution that delivers optimized, vehicle-specific performance both on and off the road.

At the heart of the Stage 3 system are ICON's 2.5 VS Piggyback shocks — front and rear — paired with a tubular steel Delta Joint Upper Control Arm (UCA) kit. The vehicle-specific shock tuning is calibrated to work in harmony with the factory torsion bar setup, providing noticeably improved ride quality over stock without sacrificing towing capacity.

Key Features:

• 2.5 Aluminum Series VS Piggyback Shocks — Front and rear; one-piece impact-extruded aluminum cylinders provide excellent corrosion resistance and a consistent finish
• Tubular Steel Delta Joint Upper Control Arms — Engineered for increased droop travel and superior structural strength
• ICON Patented Delta Joint — A heavy-duty, high-angle ball joint that combines the durability of a traditional ball joint with the articulation performance of a uniball
• 6061 Aircraft-Grade Aluminum CNC Machined Components — Precision machined for tight tolerances and long service life
• Improved Ride Quality — Noticeably smoother than stock with no reduction in towing capacity
• 0–2" Front Lift Range — Utilizes the factory torsion bar adjustment for lift

The Delta Joint technology sets this system apart from the competition. Unlike a standard uniball — which is vulnerable to contamination and corrosion in daily-driven applications — the Delta Joint features a zinc-plated housing for a first layer of corrosion resistance, a tough grease seal to keep the elements out, and a greaseable, metal-on-metal design that ensures noise-free operation and extended service life. The result is a joint that offers greater angularity than a standard ball joint while being more robust than a conventional uniball.
