ICO Box Kits

ICON-engineered custom triple-rate rear coil springs provide progressive spring rates for a comfortable on-road ride while delivering the stability and control required during aggressive off-road driving. The rear suspension is further upgraded with billet upper and high-clearance lower links that improve articulation while allowing on-vehicle adjustment for ride height and pinion angle using ICON's double adjuster system. Replaceable nylon rock sliders help protect the billet lower links from trail damage, while the adjustable billet rear track bar allows precise rear axle centering and improves suspension performance at lifted ride heights. The result is a complete, high-performance suspension system that delivers exceptional ride quality, advanced damping adjustability, and increased off-road capability with the clearance to fit 37-inch tires at full articulation. Billet aluminum upper control arms equipped with ICON's patented Delta Joint Pro (U. S. Pat. 10,731,700) provide increased strength, exceptional durability, 90 degrees of total articulation, and on-vehicle caster and camber adjustment for precise alignment and optimum drivability. The system maintains factory track width while optimized suspension geometry nearly eliminates the bump steer common to stock Tundras. High-strength one-piece ductile iron steering knuckles, high-clearance CNC laser-cut and brake-formed 1/4-inch steel crossmembers, and an integrated front skid plate provide the strength and protection required for demanding off-road conditions. High-angle greaseable outer tie rods, sway bar drop brackets, heavy-duty front and rear bump stop brackets, improved rear sway bar links and mounts, and a rear track bar bracket work together to maintain proper suspension geometry and reduce bind throughout the suspension's range of motion. The ICON Vehicle Dynamics Stage 6" Suspension System with CDXS delivers an advanced level of suspension performance, adjustability, and durability for the 2022-2026 Toyota Tundra. Designed for drivers seeking enhanced tuning capability and maximum confidence in demanding environments, this system combines ICON's 2.5 Series shock technology with premium suspension components engineered to improve ride quality, articulation, and off-road performance. Vehicle-specific tuned 2.5 Series front coilovers and rear shocks with remote reservoirs provide superior damping control, increased fluid capacity, and improved heat dissipation for consistent performance during extended off-road use. Equipped with ICON CDXS technology, all shock absorbers feature independent high-speed and low-speed compression damping adjustment, allowing precise tuning of handling response, ride quality, and suspension aggressiveness across a wide range of driving conditions. The system allows for up to a 40% increase in front wheel travel over stock without overstressing OE components and features adjustable front ride heights from 5-6 inches of lift. Through innovative engineering, the system achieves a full 6 inches of front lift with only 4 inches of crossmember drop, maximizing ground clearance while minimizing CV joint angles. 22-26 TOYOTA TUNDRA 6" STAGE SUSPENSION SYSTEM BILLET CDXS.
