ICON Vehicle Dynamics Toyota Tacoma suspension systems are designed with maximum performance and the serious driver in mind. ICON engineers’ primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality both on and off-road. The Stage 4 system includes vehicle-specific tuned 2.5” Extended Travel coilover shocks featuring remote reservoirs for exceptional cooling properties and ICON-engineered coil springs for superior vehicle “feel” through the range of travel. These coilovers are also height adjustable from 0-3.5” of lift on 2005-2015 or 0-2.75” on 2016-2023 models, allowing the use of larger, more aggressive wheel and tire combinations. When used with an ICON upper control arm, these extended travel coilovers add increased droop travel to the front suspension. The included ICON tubular upper control arm kit is designed to improve the overall performance of the Toyota Tacoma with corrected front-end geometry, built in additional caster, and improved suspension component clearance. Additionally, replacing the OE ball joint with the serviceable ICON Delta Joint allows for full bump and droop travel of the front suspension while eliminating bind. The included rear Add-A-Leaf Kit Installs in place of the factory overload leaves and effectively lowers the rear spring rate by approximately 10% for a more compliant ride while also providing 1.5" of rear lift over stock. ICON 2.0 Aluminum Series Remote Reservoir rear shocks utilize a vehicle-specific valving that balances the performance of the truck from front to rear. The ICON Vehicle Dynamics 2005-2023 Toyota Tacoma Stage 4 suspension system is an excellent choice for those drivers looking to enhance the capabilities of their pickup on the road as well as in the dirt.
