ICON Stage 4 Tubular Suspension System for 2005-2023 Toyota Tacoma

The ICON Vehicle Dynamics Stage 4 Tubular Suspension System is a complete front-and-rear upgrade for 2005–2023 Toyota Tacoma 4WD, delivering 0–3.5" of adjustable front lift on 2005–2015 models and 0–2.75" on 2016–2023 models through vehicle-specific-tuned 2.5" Extended Travel coilovers with remote reservoirs, tubular upper control arms with the patented Delta Joint, an Add-A-Leaf rear kit, and 2.0 Aluminum Series remote reservoir rear shocks.

Extended Travel With Geometry You Can Actually Use

The 2.5" Extended Travel coilovers pair remote reservoirs with ICON-engineered coil springs to keep shock fluid cooler under sustained hard use, which means damping stays consistent rather than fading on long washboard sections or repeated high-speed hits. Height adjustability across the full lift range lets you dial in ride height to match your tire and wheel choice without swapping springs. When paired with the included tubular upper control arms, the coilovers unlock additional droop travel, so the suspension can drop further into a rut or off a ledge before the wheel loses contact with the ground.

Corrected Geometry, Serviceable Hardware

The tubular upper control arm kit corrects front-end geometry, adds caster, and improves clearance for suspension components. Those changes translate to more predictable steering feel and reduced tire wear compared to running a lift on stock arms. The patented Delta Joint (U.S. Pat. 10,731,700) replaces the OE ball joint with a greaseable, zinc-plated, metal-on-metal design that tolerates the full range of bump and droop travel without bind. Unlike a standard uniball, the Delta Joint's grease seal and housing keep contaminants out, making it viable for daily-driven trucks that also see trail use.

Rear Balance, Not Just Rear Lift

The Add-A-Leaf kit installs in place of the factory overload leaves, lowering the rear spring rate by approximately 10% for a more compliant ride over rough terrain while adding 1.5" of rear lift over stock. The 2.0 Aluminum Series remote reservoir rear shocks use vehicle-specific valving to balance rear damping with the front coilovers, so the truck doesn't feel mismatched between axles.

Features

• 2.5" Extended Travel front coilovers: remote reservoirs, CAD-plated bodies, 7/8" shafts, height-adjustable 0–3.5" (2005–2015) or 0–2.75" (2016–2023)
• Tubular upper control arms with Delta Joint: corrected geometry, added caster, greaseable zinc-plated ball joint (U.S. Pat. 10,731,700)
• Add-A-Leaf rear kit: replaces OE overload leaves, ~10% lower spring rate, 1.5" rear lift over stock
• 2.0 Aluminum Series remote reservoir rear shocks: vehicle-specific valving, 5/8" shafts
• 6061 aircraft-grade aluminum CNC-machined components with FK Rod End bearings
• Fully serviceable shocks; coilover heights are calibrated for a stock-equipped vehicle

Specifications

Who This Is For and Isn't

This system suits 2005–2023 Toyota Tacoma 4WD owners who want a complete, geometry-corrected suspension upgrade for mixed on-road and off-road use, with adjustable lift height and balanced front-to-rear damping. It is compatible with OEM wheels and tires and supports aftermarket wheels up to the recommended sizes without modification.

This system does not fit 2WD Tacoma models with 5 lug wheel studs. It requires aftermarket upper control arms; the tubular UCAs included in this kit satisfy that requirement. ADAS (Advanced Driver Assistance Systems) recalibration is required after installation. The recommended 33" x 11.50" tire requires fender trimming. On 2017–2023 TRD Pro models, front lift is limited to 0–1.25" over stock and rear lift to 1" over stock. A 700 lb/in Expedition coil spring is available separately for heavier-equipped vehicles; bump stop spacer kit 51045 is also available separately to extend preload 0.25" beyond maximum.

Common Questions

Does this system work with my factory wheels and tires?

The ICON Stage 4 Tubular system is confirmed compatible with OEM Tacoma wheels and tires. For aftermarket fitments, ICON recommends 17x8.5 with 4.75" backspace, 18x9 with 5.00" backspace, or 20x9 with 5.00" backspace. The recommended tire size is 33" x 11.50"; larger tires may fit but will require fender trimming and additional modifications.

What is the lift range, and does it differ by model year?

The Stage 4 Tubular system provides 0–3.5" of adjustable front lift on 2005–2015 Tacoma models and 0–2.75" on 2016–2023 models. On 2017–2023 TRD Pro models specifically, the front lift range is limited to 0–1.25" over stock and the rear to 1" over stock. Lift heights are calibrated for a stock-equipped vehicle.

Will this fit a 2WD Tacoma?

The ICON Stage 4 Tubular system will not fit 2WD Tacoma models with 5 lug wheel studs. It is designed for 4WD Toyota Tacoma applications spanning the 2005–2023 model years.

Does installation require any recalibration or additional work?

Yes. Installing this Stage 4 system requires recalibration of Advanced Driver Assistance Systems (ADAS) after the install is complete. The tubular UCAs included in the kit satisfy the aftermarket upper control arm requirement. Fender trimming is required if running the recommended 33" x 11.50" tire size.

What components are included in the Stage 4 Tubular kit?

The kit includes 2.5" Extended Travel coilovers with remote reservoirs (front), tubular upper control arms with the patented Delta Joint, an Add-A-Leaf rear kit that replaces the factory overload leaves, and a pair of 2.0 Aluminum Series remote reservoir rear shocks with vehicle-specific valving. Bump stop spacer kit and Expedition coil springs are sold separately.
