ICON K53028 Stage 8 Suspension System with Billet Upper Control Arms for 2007-2021 Toyota Tundra

The Stage 8 system includes vehicle-specific tuned 2.5 Series coilover shocks featuring a remote reservoir for exceptional cooling properties and ICON-engineered Eibach coil springs for superior vehicle “feel” through the range of travel. These coilovers are also height adjustable from 1-3” of lift over stock allowing the use of larger, more aggressive wheel and tire combinations. Used in conjunction with the included ICON upper control arm, these coilovers increase droop travel to the front suspension. To increase the ride quality of the truck and gain additional droop travel, the ICON RXT multi-rate leaf springs are added to the rear. Designed with an additional leaf (included with kit) that can be exchanged or added to the pack to yield additional spring rate, this leaf spring is perfect for drivers seeking improved rear ride quality in an “unloaded” vehicle as well as those that are have outfitted their trucks with a significant amount of weight in the form of a bed rack, roof top tent, spare tires, parts, or other additions. To compliment this increase in rear wheel travel the Stage 8 system includes a unique 2.5 Aluminum Series RXT remote reservoir shock that features a side-mount eyelet that making it shorter in collapsed length, longer at extension, and still fits in the factory mounting location. A large ten-inch remote reservoir was added to aid in heat dissipation and resist shock fade during spirited driving. 2007-2021 TUNDRA 1-3" LIFT STAGE 8 SUSPENSION SYSTEM WITH BILLET UPPER CONTROL ARMS APPLICATION NOTE #87: INSTALLATION OF COMPLETE ICON SYSTEM REQUIRED TO ATTAIN ADVERTISED WHEEL TRAVEL. USE OF ANY OTHER MANUFACTURERS COMPONENTS WILL NOT PROVIDE ADVERTISED WHEEL TRAVEL AND COULD CAUSE UNKNOWN DAMAGE.

• 2.5 Aluminum Series RXT rear shocks feature one-piece impact extruded aluminum cylinders for excellent corrosion resistance and consistent finish
• 10” aluminum reservoirs in RXT shocks provide generous oil and nitrogen volume for consistent damping as shock temperature increases
• Unique side-mounted lower eyelet allows for increased rear shock travel while utilizing factory mounting location
• Vehicle-specific tuned front and rear shocks for superior shock damping and control
• Increased wheel travel when used with RXT shock without sacrificing up-travel
• 3 user-adjustable rear leaf spring rates for unique vehicle configurations
• Galvanized leaf separators reduce friction and aid in corrosion resistance
• Corrosion resistant CAD plated coilover shock bodies with 7/8" shafts
• FK Rod End bearings for extended longevity and minimal deflection
• Bolt-on system means no cutting or welding necessary for install
• Military wrap front leaf spring eyelets for increased durability
• Leaf spring tip inserts reduce noise and increase ride comfort
• Adjustable coilovers provide 1-3" of front lift height
• 6061 aircraft grade aluminum CNC machined components
• Increased wheel travel and ride quality over stock
• Shocks are fully rebuildable and revalveable

The ICON K53028 Stage 8 Suspension System is engineered for 2007-2021 Toyota Tundra models seeking improved ride quality, increased wheel travel, and adjustable front lift. The system includes vehicle-specific 2.5 Series front coilover shocks with remote reservoirs, ICON-tuned Eibach coil springs, billet upper control arms, ICON RXT multi-rate rear leaf springs, and 2.5 Aluminum Series RXT rear remote-reservoir shocks. Adjustable front coilovers provide 1–3 inches of lift over stock, supporting larger and more aggressive wheel and tire combinations while increasing front suspension droop travel when used with the included upper control arms.
The rear RXT leaf springs are designed with an additional interchangeable leaf, providing three user-adjustable spring rates for different vehicle configurations. This flexibility helps improve unloaded ride quality while accommodating added equipment such as a bed rack, rooftop tent, spare tire, or trail gear. The RXT rear shocks feature one-piece impact-extruded aluminum cylinders, large 10-inch remote reservoirs, and unique side-mounted lower eyelets. Together, these features increase rear shock travel, improve heat dissipation, and help maintain consistent damping during demanding driving.
The ICON K53028 is a bolt-on suspension system requiring no cutting or welding. Corrosion-resistant coilover bodies, 7/8-inch shafts, FK rod-end bearings, galvanized leaf separators, military-wrap front leaf spring eyelets, and leaf spring tip inserts support long-term durability and reduced friction and noise. The shocks are fully rebuildable and revalveable, while CNC-machined 6061 aircraft-grade aluminum components provide precise fitment and dependable performance. Complete installation of the ICON system is required to achieve the advertised wheel travel; combining components from other manufacturers may reduce performance or cause damage.
