ICON Stage 4 Suspension System for 2024-2026 Toyota Tacoma 1.25-3" Lift Billet UCA Triple Rate Rear Springs

The ICON Vehicle Dynamics Stage 4 Suspension System fits 2024–2026 Toyota Tacoma trucks and delivers 1.25–3" of adjustable front lift and 0.5" of rear lift through a five-component kit built around 2.5 Series remote reservoir coilovers front and rear, billet aluminum upper control arms with the Delta Joint PRO, and triple-rate rear coil springs. The system is configured for 4WD models and is also installable on 2WD Tacomas with the differential drop kit omitted.

Remote Reservoirs and What They Actually Do

The 2.5 Series front coilovers and rear shocks both use remote reservoirs, which increase shock oil volume and expand the heat-dissipation surface area. On washboard roads, rocky descents, and repeated whoops, shock oil heats up and can cavitate, causing damper fade and a sudden loss of controlled feel. The larger oil volume and external reservoir surface delay that threshold significantly, keeping damping consistent deeper into a trail run than a standard shock body allows.

Corrected Geometry Through the Full Travel Range

The billet aluminum upper control arms replace the OE arms with components that correct front-end geometry, add on-vehicle camber and caster adjustment, and improve clearance for suspension components at full droop and full bump. The Delta Joint PRO replaces the OE ball joint with a serviceable, rebuildable unit that provides 90 degrees of total articulation, eliminating the bind that limits travel with a conventional ball joint. The front differential drop brackets and coilover lengths are matched to maximize available front travel and prevent CV bind on 4WD models.

Triple-Rate Rear Springs for On-Road and Off-Road Balance

The rear triple-rate coil springs use a softer rate through droop and normal ride travel, then transition to a firmer overload rate as compression increases. The result is a compliant on-road ride that resists bottoming under load or hard off-road use. The 2.5 Aluminum Series rear shocks carry vehicle-specific valving tuned to work with the front coilovers, balancing damping performance from front to rear rather than treating each end independently.

Features

• 2.5 Series front coilovers with remote reservoirs: height adjustable 1.25–3" over stock, corrosion-resistant CAD-plated bodies, 7/8" shafts, ICON-engineered coil springs
• Billet aluminum UCAs with Delta Joint PRO: corrected geometry, on-vehicle camber/caster adjustment, 90° articulation, serviceable and rebuildable (U.S. Pat. 10,731,700)
• Front differential drop kit (4WD): maximizes front suspension travel and prevents CV bind; polyurethane differential mounting bushings limit differential movement under load
• 2.5 Aluminum Series remote reservoir rear shocks: integrated bump zones, vehicle-specific valving, 7/8" shafts, FK Rod End bearings
• Triple-rate rear coil springs: 0.5" rear lift, softer droop/ride rate with firmer overload rate for bottoming resistance
• 6061 aircraft-grade aluminum CNC-machined components throughout

Who This Is For and Isn't

This system suits 2024–2026 Toyota Tacoma owners, whether 4WD or 2WD, who want a comprehensive front and rear suspension upgrade with 1.25–3" of adjustable front lift, corrected geometry, and improved damping for mixed on-road and off-road use including trails, washboard, and loaded touring.

This kit does not fit Tacoma submodels equipped with rear leaf springs, or any Tacoma equipped with Adaptive Variable Suspension (AVS). It is not configured for 2WD out of the box (the differential drop kit is not needed for 2WD, and 2WD-specific kits are listed separately when available). Advanced Driver Assistance Systems (ADAS) require recalibration after installation. An adjustable track bar is recommended to realign the rear axle after installation but is not included.

Common Questions

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

The ICON Stage 4 kit is configured for 4WD Tacomas and includes the front differential drop kit (part 55160) required for 4WD models. On a 2WD Tacoma, the differential drop kit is not needed and the remaining suspension components can be installed with full system functionality. A 2WD-specific kit is listed separately when available.

Will this kit fit a Tacoma with Adaptive Variable Suspension?

No. The ICON Stage 4 Suspension System for the 2024–2026 Toyota Tacoma is not compatible with Tacoma models equipped with the factory Adaptive Variable Suspension (AVS) system. Confirm your Tacoma's suspension configuration before ordering.

Does this kit fit Tacomas with rear leaf springs?

No. The ICON Stage 4 kit includes triple-rate rear coil springs and rear coilover shocks and will not fit 2024–2026 Tacoma submodels that came from the factory with rear leaf springs. Check your build sheet or door-jamb sticker to confirm your rear suspension type.

What lift height can I expect, and does adding accessories affect it?

The front coilovers are adjustable from 1.25–3" of lift over stock, and the rear springs provide 0.5" of lift over stock. Both figures apply to a stock-equipped vehicle. Adding accessories such as roof racks, bumpers, and overland gear increases vehicle weight and will reduce the achieved lift height within that range.

Do I need to recalibrate any driver-assistance systems after installing this kit?

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 typically requires a visit to a dealer or a shop with the appropriate calibration equipment.
