ICON Stage 9 Billet UCA Coilover Kit – 0–3.5 Inch Adjustable Suspension for 10–24 Toyota 4Runner

This Stage 9 suspension system delivers 0–3.5 inches of precise lift for 2010–2024 Toyota 4Runner models by combining heavy-duty coilover adjustments with precision-billet upper control arms, eliminating factory geometry flaws like bump steer, poor caster alignment, and rapid ball-joint wear.

• Adjustable Lift Range: Coarse-thread adjustment collars provide 0–3.5 inches of tuning latitude, letting you dial in exact ride height for wheel fitment or ground clearance while preserving full suspension extension and rebound control.
• Billet Upper Control Arms: Machined billet aluminum brackets replace stamped OE units to correct track width and caster angles, ensuring predictable steering response, reduced vibration, and extended ball-joint service life under heavy loads.
• Factory-Good Mounting Pattern: Designed around OEM frame mounting points for a direct-bolt installation that retains stock crash-sensor connectivity and requires no drilling, welding, or structural modifications to the unibody rails.
• Tuned Load Handling: Optimized spring and damper matching supports higher sprung masses typical of equipped 4Runners and winch installations, maintaining level posture and controlled damping without sag or harshness.
• Durable Component Construction: Utilizes hard-coated finishes and reinforced mounting designs to withstand impact damage in off-road environments and resist corrosion from moisture, mud, and road salts.
• Holistic Alignment Correction: Upgrading with this complete front kit restores proper scrub radius and tie-rod geometry, solving the uneven tire wear and steering instability that occur with partial lift or non-matching components.
