ICON Vehicle Dynamics 2007-2021 Toyota Tundra 1-3" Lift Stage 9 Suspension System with Billet UCA

The ICON Vehicle Dynamics Stage 9 Suspension System is a complete front-and-rear upgrade for 2007–2021 Toyota Tundra trucks, delivering 1–3 inches of adjustable front lift through vehicle-specific tuned 2.5 Series remote-reservoir coilovers paired with ICON RXT multi-rate rear leaf springs and RXT-specific 2.5 Series rear shocks. The system ships as five component assemblies and is designed as a bolt-on install requiring no cutting or welding.

Shipping: ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.

Adjustable Compression Damping Front and Rear

Both the front coilovers and the rear RXT shocks include ICON's CDC (Compression Damping Control) Valve, which provides ten settings of compression adjustment without tools. For a Tundra that moves between unladen daily driving, loaded overland trips, and rougher terrain, the ability to dial compression at the shock rather than returning to a shop means the suspension can be matched to the actual load and surface rather than compromised for an average of both.

RXT Rear Leaf Springs Built for Loaded Trucks

The ICON RXT multi-rate leaf pack includes an add-in leaf that can be exchanged or added to the pack to change spring rate, giving three distinct rear spring configurations. Galvanized leaf separators reduce friction and corrosion between leaves, military-wrap front eyelets reinforce the spring ends, and leaf tip inserts reduce noise. For Tundra owners running a bed rack, rooftop tent, spare tires, or other significant bed weight, the ability to tune rear spring rate to the actual load rather than accepting a fixed rate is a practical advantage over a standard replacement spring.

Billet UCA with ICON's Patented Delta Joint

The included billet 6061 aluminum upper control arm uses ICON's patented Delta Joint, a greaseable high-angle ball joint with a zinc-plated housing and a grease seal that blocks contamination. Compared to a standard uniball, the Delta Joint adds corrosion resistance and a sealed grease path; compared to a conventional ball joint, it allows greater angularity. Used with the front coilovers, the UCA increases front droop travel beyond what the factory arm allows.

Who This Is For and Isn't

The Stage 9 system suits 2007–2021 Toyota Tundra owners who want a complete front-and-rear suspension upgrade with adjustable lift, tunable compression damping, and a rear spring system that can be configured for both unladen daily use and heavily loaded overland builds.

This system does not fit Tundra trucks equipped with the TRD rear sway bar kit. The complete Stage 9 system must be installed as a unit to achieve the stated wheel travel figures; substituting components from other manufacturers will not provide the advertised travel and may cause unknown damage. Recommended 35" tires require fender trimming.

Common Questions

Does this system fit a Tundra with the TRD rear sway bar kit installed?

The ICON Stage 9 Suspension System for 2007–2021 Toyota Tundra is not compatible with the TRD rear sway bar kit. The TRD sway bar kit must be removed before installing this system.

Can OEM wheels and tires be used after installing this system?

Yes. The ICON Stage 9 system for 2007–2021 Toyota Tundra is confirmed to fit with OEM wheels and tires. Recommended aftermarket tire size is 35 x 12.50", though that size requires fender trimming; larger tires require additional fender modification.

How is the front lift height adjusted?

Front lift on the Stage 9 system is set by adjusting the threaded coilover body. The coilovers are height-adjustable from 1 to 3 inches. Lift heights indicated are for a stock-equipped vehicle; a bump stop spacer kit is available separately to increase thread engagement beyond the maximum recommendation.

What does the CDC Valve do, and how is it adjusted?

The CDC (Compression Damping Control) Valve provides 10 settings of compression damping adjustment on both the front coilovers and the rear RXT shocks in the Stage 9 system. Adjustments are made by the end user to match terrain conditions and cargo load without returning to a shop.

What is included in the Stage 9 kit?

The Stage 9 kit for 2007–2021 Toyota Tundra includes: one 2.5 VS remote-reservoir CDCV front coilover kit, one billet UCA Delta Joint kit, two RXT multi-rate rear leaf packs each with an add-in leaf, one Toyota rear 8.0" U-bolt kit, and one RXT rear 2.5 VS remote-reservoir CDCV shock pair. The system ships in multiple boxes.
