ICON 58755 – 3.0 Series Coilover Kit (Remote Reservoir w/ CDCV) for 2007–2021 Toyota Tundra / 2008–2022 Toyota Sequoia

The ICON Vehicle Dynamics 3.0 Series Coilover Kit is engineered for Tundra and Sequoia owners demanding the highest level of suspension performance. While ICON’s 2.5 Series coilovers deliver a strong all-around upgrade, the 3.0 Series is built for extreme off-road use, aggressive driving, and rugged terrain where maximum control, stability, and damping are required.

Featuring massive 3.0” shock bodies, these coilovers provide a 50% increase in piston surface area in the ride zone and 100% in the bump zone compared to 2.5 Series units. This results in dramatically improved bottom-out resistance, enhanced vehicle control at high speeds, and superior handling during hard impacts or unexpected obstacles. ICON’s multi-stage hydraulic Bump Zone technology keeps the suspension composed through the last 40% of travel, delivering exponential damping when it matters most.

These coilovers offer 1.63–3.5 inches of ride height adjustability, allowing room for larger wheel/tire combinations while improving stance and off-road capability. Installation is straightforward thanks to a direct bolt-in OEM-replacement design. Equipped with high-quality components—including ICON-engineered coil springs, FK Rod End bearings, and CNC-machined shock shafts—this system ensures long-term durability and premium performance both on and off the trail.
