ICON Vehicle Dynamics 2005-2023 Toyota Tacoma Stage 3 EXP Suspension System with Tubular UCA

The ICON Vehicle Dynamics Stage 3 EXP Suspension System is a complete front-and-rear upgrade for 2005–2023 Toyota Tacoma 4WD trucks, delivering 1–2 inches of adjustable front lift and 1.5 inches of rear lift while retaining the factory coil spring up front. The system pairs 2.5 EXP Series front coilovers with a tubular upper control arm, sway bar relocation brackets, a rear add-a-leaf kit, and 2.0 Aluminum Series remote reservoir rear shocks, all matched and tuned to work together. It supports fitment of up to 33-inch tires and is available as a single kit (SKU K53222T).

EXP Coilovers: Coilover Performance Without Replacing the Factory Spring

The 2.5 EXP Series front coilovers use a 2.5-inch diameter, fully rebuildable shock body paired with the Tacoma's existing factory coil spring and coil hardware. A snap-ring adjustment provides 1–2 inches of front lift over stock, letting owners dial in ride height without purchasing separate springs. The EXP format sits between a spacer lift and a full threaded-body coilover in both cost and capability, delivering custom-tuned performance and maximum travel without the expense of a complete spring replacement.

Corrected Geometry Up Front, Improved Ride Quality Out Back

The tubular upper control arm kit restores and improves front-end geometry by adding caster correction and increasing clearance around suspension components. The ICON Delta Joint (U.S. Pat. 10731700) replaces the OEM ball joint and allows full bump and droop travel without bind. The Delta Joint is a serviceable design that can be maintained over the life of the vehicle rather than replaced as a sealed unit. Sway bar relocation brackets keep the sway bar clear of the EXP coilovers through the full range of wheel travel, so no OEM components are overstressed.

At the rear, the 3-leaf add-a-leaf kit installs in place of the OEM overload leaf, softening the spring rate ramp-up that makes stock Tacomas ride harshly when unloaded. The result is 1.5 inches of rear lift alongside a more compliant ride on pavement and trail. The 2.0 Aluminum Series remote reservoir rear shocks are nitrogen-charged monotubes, fully rebuildable and tuned to complement the 2.5 EXP fronts for balanced vehicle control across both axles.

Specifications

Who This Is For and Isn't

This system suits 2005–2023 Toyota Tacoma 4WD owners who want a complete, matched suspension upgrade with 1–2 inches of adjustable front lift, 1.5 inches of rear lift, corrected front geometry, and support for up to 33-inch tires, whether the primary use is daily driving, weekend overlanding, or mixed on- and off-road use.

This system does not fit 2005–2015 rear-wheel-drive Tacomas with 5 lug studs, and it is not compatible with the TRD Pro Tacoma. It does not include a replacement front coil spring; the factory spring is reused. Recommended aftermarket wheel and tire sizes may require minor fender trimming.

Common Questions

Does this system require replacing the factory front coil spring?

No. The Stage 3 EXP system's 2.5 EXP Series front coilovers are designed to reuse the Tacoma's factory coil spring and coil hardware. This is a defining feature of the EXP format: the 2.5-inch shock body provides custom-tuned performance and lift without the cost of purchasing new springs.

How much lift does this system provide?

The Stage 3 EXP system provides 1–2 inches of front lift, adjustable via snap ring, and 1.5 inches of rear lift over stock. Lift figures are based on a stock-equipped vehicle; actual lift may vary with accessories, payload, or worn OEM components.

Will this system fit a TRD Pro Tacoma or a rear-wheel-drive Tacoma?

No. The Stage 3 EXP system (SKU K53222T) is not compatible with the TRD Pro Tacoma and is not compatible with 2005–2015 rear-wheel-drive Tacomas equipped with 5 lug studs. It is designed for 4WD Tacoma applications in the 2005–2023 model year range.

What tire sizes will fit after installing this system?

The Stage 3 EXP system supports OEM wheels and tires and is designed to accommodate up to 33×11.50-inch aftermarket tires. Minor fender trimming may be required for the recommended 33-inch tire size. ICON Alloys wheels in 17×8.5, 18×9, and 20×9 are noted as compatible aftermarket options.

Are the shocks in this system rebuildable?

Yes. The 2.5 EXP Series front coilovers and the 2.0 Aluminum Series rear shocks included in the Stage 3 EXP system are both fully rebuildable and re-tunable, supporting long-term serviceability rather than requiring full replacement when worn.
