ICON Vehicle Dynamics UCA Replacement Bushing and Sleeve Kit for Toyota and Lexus

The ICON Vehicle Dynamics UCA Replacement Bushing and Sleeve Kit restores the inner pivots of ICON tubular front upper control arms (part numbers 58450, 58450DJ, 58451, and 58451DJ) to like-new condition, and fits 2005–2023 Toyota Tacoma, 2003–2024 Toyota 4Runner, 2003–2023 Lexus GX, and 2007–2014 Toyota FJ Cruiser vehicles equipped with those arms.

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.

Genuine Components, Precise Fit

Each kit contains genuine ICON Vehicle Dynamics original parts, matched to the exact tolerances of ICON's own tubular upper control arms. The polyurethane hat bushings are application-specific, meaning they are shaped and durometer-rated for this arm geometry rather than adapted from a generic bushing. Using the correct bushing profile prevents the side-loading and accelerated wear that generic replacements can introduce at the inner pivot.

Full Inner-Pivot Service in One Box

The kit covers both arms in the pair: polyurethane hat bushings, Delrin load rings, and CNC machined steel zinc-plated sleeves are all included. Delrin load rings reduce friction at the pivot interface without requiring grease, and the zinc-plated steel sleeves resist corrosion in the same environment that wore out the originals. Having every component in one shipment means the job does not stall waiting on a second order.

Specifications

Who This Is For and Isn't

This kit is for owners of 2005–2023 Toyota Tacoma, 2003–2024 Toyota 4Runner, 2003–2023 Lexus GX, or 2007–2014 Toyota FJ Cruiser trucks and SUVs that are already running ICON tubular front upper control arms (part numbers 58450, 58450DJ, 58451, or 58451DJ) and need to restore worn inner pivot components.

This kit does not fit any other ICON upper control arm part numbers, OEM factory control arms, or aftermarket UCAs from other brands. It is not a complete control arm and does not include the arm tubes, ball joints, or any hardware beyond the bushings, load rings, and sleeves.
