ICON 2007-2021 Toyota Tundra 1-3in Stage 1 Suspension System| K53021

If you’re driving a 2007–2021 Toyota Tundra and ready to elevate the way your truck handles, ride and performs, the ICON Vehicle Dynamics Stage 1 Suspension System (PN K53021) delivers a technically advanced solution built for serious drivers. This isn’t just a lift kit—it’s a comprehensive suspension upgrade engineered to unlock measurable improvements in control, comfort and capability.

Why you should buy

• Precision-engineered damping & travel: ICON’s primary goal with this design was to increase wheel travel and refine damping characteristics — meaning your Tundra responds sharply to inputs, yet rides smoothly over rough surfaces. 

• Adjustable lift height (1-3″): With front coilovers adjustable from 1″ up to 3″ of lift height, you gain flexibility—whether you want a subtle raise or more aggressive stance. 

• Premium construction & materials: Featuring 6061 aircraft-grade aluminum CNC-machined components, a corrosion-resistant CAD-plated coilover body with 7/8″ shaft, and FK rod-end bearings to minimize deflection and extend durability. 

• Balanced front & rear tuning: The system pairs 2.5″ diameter front coilovers with ICON’s 2.0 VS Aluminum Series rear shocks—both valved specifically for the Tundra—to deliver well-balanced control from front to rear. 

• Maintains towing capacity & OEM fitment: Despite the upgrade, the system is designed to maintain your truck’s towing ability while remaining 100% bolt-on with no drilling, cutting or welding required. 

What you’ll feel driving

• Sharper cornering and reduced body roll: The tuned shocks and coilover design significantly reduce lateral motion and body lean, giving you tighter steering response and more confidence when carving corners or navigating uneven terrain.

• Improved ride comfort on rough surfaces: With greater wheel travel and superior damping control, potholes, washboard roads and off-road chatter become far less jarring.Your truck feels more planted.

• More clearance and room for bigger tires: The lift height enables fitting larger, more aggressive tire setups while preserving clearance and stance—ideal for both aesthetic and performance upgrades. 

• Durable, long-term performance: High-end materials and serviceable shocks mean this upgrade isn’t just for one season. You’ll benefit from consistent performance over time.

Technical highlights

• Fully adjustable front coilover assembly calibrated for the Tundra’s front geometry.

• Rear shock absorbers with vehicle-specific valving optimized for load and travel characteristics.

• 6061 alloy components ensure higher strength-to-weight ratio compared to typical stamped steel kits.

• CAD-plated and anodized finishes combat corrosion, especially important in harsh weather or off-road environments.

• 100% bolt-on installation avoids frame modifications, making future servicing or resale simpler.

Fitment & other notes

• Compatible with 2007–2021 Toyota Tundra (2WD and 4WD). 

• Supports OEM wheels and tires; recommended aftermarket tire size up to 35″ × 12.50″ with proper clearance and trims. 

• While lift extends to ~3″, application notes advise that above ~2.5″ of lift the factory upper control arms (UCAs) may require replacement for ideal alignment. 

Investing in the ICON K53021 Stage 1 Suspension System means your Tundra won’t just look better—it will perform better. From daily drives to off-road excursions, you’ll experience a noticeable upgrade in how your truck handles, how it absorbs the road, and how it responds. For drivers who demand more than stock performance, this system delivers.
