TRU specialist notes

From the Trucks R Us fitment and install team, beyond the manufacturer's information.

  • Plan for a professional wheel alignment after installing any lift or leveling kit.
  • Going to bigger tires as well? Speedometer recalibration may be needed, and some tire and wheel combinations need trimming. Check the recommended wheels and tires, or ask us before you order.

    Overview

    ICON Vehicle Dynamics 2025-2026 Toyota 4Runner 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 6 system includes vehicle-specific tuned 2.5 Series 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 height adjustable from 1.75-3” of front lift height over stock, allowing the use of larger, more aggressive wheel and tire combinations. Remote reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. The combination of front differential drop brackets and ICON’s specifically designed coilover lengths maximizes the available front suspension travel and prevents CV bind. Additionally, polyurethane differential mounting bushings replace the soft OE bushings to help limit differential movement under load.

    The included ICON tubular upper control arm kit is designed to improve overall performance with corrected front-end geometry, built in additional caster, and improved suspension component clearance. Additionally, replacing the OE ball joint with the all-new, serviceable, and rebuildable ICON Delta Joint PRO allows for full bump and droop travel of the front suspension while eliminating bind. The dual-rate rear coil design provides a softer ride height spring rate with a firmer overload rate that combine to deliver on-road comfort with excellent bottoming resistance and superior off-road performance while .75” of rear lift height over stock allows a for level stance front to rear. The ICON Billet Adjustable Rear Track Bar helps re-center the rear axle and double adjuster rod end threads allow easy "on-vehicle" fine adjustment of track bar length without requiring removal or disassembly of the track bar. ICON 2.5 Aluminum Series remote reservoir rear shocks with integrated bump zones provide improved shock damping ability and utilize a vehicle-specific valving that balances the performance of the truck from front to rear. The ICON Vehicle Dynamics 2025-2026 Toyota 4Runner Stage 6 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.
