ICON Stage 4 Billet Suspension System for 2024-2026 Toyota Tacoma with Overland Rear Springs

The ICON Vehicle Dynamics Stage 4 Suspension System is a complete front and rear upgrade for 2024–2026 Toyota Tacoma trucks, delivering 1.25–3" of adjustable front lift and approximately 0.5" of rear lift through a matched set of 2.5 Series remote reservoir coilovers, billet aluminum upper control arms with Delta Joint PRO, a front differential drop kit, 2.5 Aluminum Series remote reservoir rear shocks, and Overland dual-rate rear coil springs. This kit is configured for 4WD models; a 2WD installation is possible without the differential drop kit.

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.

Remote Reservoirs That Resist Fade Under Hard Use

The 2.5 Series front coilovers and 2.5 Aluminum Series rear shocks both use remote reservoirs to increase shock oil volume and heat-dissipation surface area. Conventional shocks subjected to sustained off-road use (repeated high-speed whoops, loaded trail runs, or back-to-back descents) overheat and cavitate, causing damper fade and unpredictable handling. The added oil capacity in these reservoirs delays that onset, keeping damping consistent when the terrain demands it most. Shock bodies are CAD-plated for corrosion resistance and feature 7/8" shafts; shocks are fully serviceable.

Corrected Geometry Through the Full Range of Travel

The billet 6061 aircraft-grade aluminum upper control arms restore and improve front-end geometry that stock arms compromise when lift is added. On-vehicle camber and caster are adjustable, and the arms accept the ICON Delta Joint PRO, a serviceable, rebuildable ball joint with 90 degrees of total articulation (U.S. Pat. 10,731,700) that allows full bump and droop travel without bind. The front differential drop brackets, included for 4WD models, maximize available wheel travel and keep CV joints operating within their designed angle range.

Dual-Rate Rear Springs Tuned for Loaded Overlanders

The Overland rear coil springs use a dual-rate design: a softer initial rate for unloaded on-road comfort, transitioning to a firmer overload rate that resists bottoming and supports heavy rear loads. Springs are rated to net approximately 0.5" of rear lift with roughly 600 lb of additional weight in the rear, and the lift range shifts as rear load increases or decreases. The 2.5 Aluminum Series rear shocks use vehicle-specific valving to balance rear damping with the front coilovers, and integrated bump zones add a final layer of bottoming resistance.

Features

• 2.5 Series front coilovers with remote reservoirs: height-adjustable 1.25–3" front lift over stock, CAD-plated bodies, 7/8" shafts
• Billet aluminum UCAs with Delta Joint PRO: corrected geometry, on-vehicle camber/caster adjustment, 90° articulation, U.S. Pat. 10,731,700
• Front differential drop kit (4WD): maximizes wheel travel and prevents CV bind; polyurethane differential mounting bushings included
• 2.5 Aluminum Series remote reservoir rear shocks: vehicle-specific valving, integrated bump zones, fully serviceable
• Overland dual-rate rear coil springs: ~0.5" rear lift at ~600 lb added rear weight, bottoming resistance, FK Rod End bearings
• 6061 aircraft-grade aluminum CNC-machined components throughout

Specifications

Who This Is For and Isn't

This Stage 4 system suits 2024–2026 Toyota Tacoma owners (4WD or 2WD) who want a complete, geometry-corrected suspension upgrade with adjustable front lift, heavy-duty remote reservoir damping, and rear spring support for outfitted overlanding builds carrying significant rear loads.

This kit will not fit 2024–2026 Tacoma submodels equipped with rear leaf springs, and it is not compatible with Adaptive Variable Suspension (AVS) equipped vehicles. ADAS recalibration is required after installation. An adjustable track bar is recommended to realign the axle after installation but is not included. OEM wheels and tires are compatible, though aftermarket fitment beyond 33" x 11.50" may require fender trimming.

Common Questions

Does this kit fit both 4WD and 2WD 2024–2026 Tacomas?

The Stage 4 system is configured for 4WD models and includes the front differential drop kit (part 55160). A 2WD Tacoma can use the remaining suspension components without the differential drop kit; ICON notes that 2WD-specific kits are forthcoming, and individual components are available separately for a 2WD build.

Will this system work on a Tacoma equipped with Adaptive Variable Suspension?

No. The ICON Stage 4 Suspension System for the 2024–2026 Toyota Tacoma is not compatible with Adaptive Variable Suspension (AVS) equipped vehicles. Buyers should confirm their Tacoma's suspension configuration before ordering.

What rear lift height should I expect, and does it change with load?

The Overland rear coil springs in this Stage 4 kit are designed to net approximately 0.5" of rear lift with roughly 600 lb of additional weight in the rear. Lift height will increase with less rear load and decrease with more; the dual-rate spring design accommodates a range of loaded and unloaded conditions.

Is ADAS recalibration required after installing this suspension system?

Yes. Installing the ICON Stage 4 Suspension System on a 2024–2026 Toyota Tacoma requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation. This work is typically performed by a Toyota dealer or a shop with the appropriate calibration equipment.

Are the shocks in this kit serviceable?

Yes. Both the 2.5 Series front coilovers and the 2.5 Aluminum Series rear shocks in this Stage 4 system are fully serviceable, and the Delta Joint PRO ball joint in the billet upper control arms is also serviceable and rebuildable.
