ICON Vehicle Dynamics Tubular Front Upper Control Arms with Delta Joint PRO for 2024-2026 Toyota Tacoma / Land Cruiser 250 / Lexus GX550 and 2025-2026 4Runner

The ICON Vehicle Dynamics Tubular Front Upper Control Arms with Delta Joint PRO are heavy wall 1026 DOM steel UCAs built for the 2024–2026 Toyota Tacoma, 2024–2026 Toyota Land Cruiser 250 Series, 2024–2026 Lexus GX550, and 2025–2026 Toyota 4Runner, compatible with 1.25–3 inches of front lift over stock. Built-in added caster corrects front-end geometry on lifted vehicles, and the Delta Joint PRO delivers 90 degrees of bind-free articulation for maximum suspension travel with performance coilovers.

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.

Bind-Free Travel Through the Full Range

The Delta Joint PRO provides 90 degrees of articulation (a 14% improvement over ICON's standard Delta Joint), so the front suspension moves through its complete travel without binding against the upper control arm. For a lifted Tacoma, 4Runner, Land Cruiser 250, or GX550 running performance coilovers, that means the shock can use every inch of its stroke rather than being cut short by joint bind, translating directly into better wheel contact and a more controlled ride over rough terrain.

Serviceable Components, Not Disposable Ones

The Delta Joint PRO is fully rebuildable: any individual component, including the ball, shaft, or race, can be removed, inspected, and replaced without purchasing a whole new joint. The chromoly ball and shaft are hardened to Rockwell C 55, and the replaceable races are graphite-impregnated sintered metal machined to tight tolerances for a metal-to-metal bearing interface. A redesigned lubrication system distributes grease through internal channels without extending past the bearing seal, and the grease fitting is protected by an included anodized billet aluminum dust cap. The dual-stage polyurethane pivot bushings at the frame mounts are equally serviceable, greaseable, rebuildable, and seated in precision-machined housings.

Constructed for Long-Term Durability

Each arm is CNC formed from heavy wall 1026 DOM tubing and fixture welded before receiving a multi-stage semi-gloss black powder coat finish. The tubular construction delivers the geometry correction and travel gains of an aftermarket UCA at a lower price point than ICON's billet upper control arms, while still including all hardware necessary for a complete installation.

Specifications

Who This Is For and Isn't

These UCAs suit owners of 2024–2026 Toyota Tacoma, 2024–2026 Toyota Land Cruiser 250 Series, 2024–2026 Lexus GX550, or 2025–2026 Toyota 4Runner running 1.25–3 inches of front lift who want maximum coilover travel, corrected caster geometry, and a fully serviceable upper joint without stepping up to billet-arm pricing.

These arms are not compatible with vehicles outside the stated model years and platforms, and are not designed for stock-height or lift applications below 1.25 inches or above 3 inches over stock. Tires larger than 33x11.50 inches may require fender trimming and additional modifications.

Common Questions

Which vehicles do these upper control arms fit?

The ICON Tubular UCAs with Delta Joint PRO (SKU 58452DJ) fit the 2024–2026 Toyota Tacoma, 2024–2026 Toyota Land Cruiser 250 Series, 2024–2026 Lexus GX550, and 2025–2026 Toyota 4Runner. No other makes, models, or model years are confirmed compatible.

What lift range are these UCAs designed for?

These ICON tubular upper control arms are compatible with 1.25 to 3 inches of front lift over stock. Applications outside that range are not supported by this part's application note.

What makes the Delta Joint PRO different from ICON's standard Delta Joint?

The Delta Joint PRO delivers 90 degrees of articulation (14% more range of motion than ICON's standard Delta Joint) and uses a larger ball with 56% more bearing surface. It is fully rebuildable by component, hardened to Rockwell C 55, and features a redesigned internal lubrication system with improved grease distribution.

Are the bushings and joint serviceable after installation?

Yes. The Delta Joint PRO is designed so any individual component can be removed, inspected, and replaced without replacing the entire joint. The dual-stage polyurethane pivot bushings at the frame mounts are also greaseable and rebuildable, seated in precision-machined housings.

Does the kit include everything needed for installation?

These ICON tubular UCAs include all components and hardware necessary for a complete installation, along with anodized billet aluminum dust caps for the Delta Joint PRO grease fitting. An installation guide is available from ICON. The ICON Needle Grease Gun Adapter Kit is sold separately.
