Front Upper Control Arms with Ball Joint for 4Runner GX Series - 2-4in

In this review the reviewer examines the Front Upper Control Arms with Ball Joint as a practical replacement for owners of 2003-2024 Toyota 4Runner, 2007-2014 FJ Cruiser and compatible Lexus GX models. The bottom line: these control arms are aimed at drivers who want a straightforward OEM-replacement part that also provides a 2-4in lift without changing stock shocks, and the single biggest reason to buy is the combination of heavy-duty construction and upgraded PU bushings that improve off-road stability and cold-weather performance.

Key Features

• Fitment: Direct-fit compatibility with 2003-2024 Toyota 4Runner, 2007-2014 FJ Cruiser, 2003-2009 Lexus GX470 and 2010-2023 Lexus GX460 for a plug-and-play replacement.
• Lift capability: Designed to provide a 2-4in lift which lets owners increase ride height while retaining stock wheel fitment.
• Durable construction: Heavy-duty tubular alloy steel construction improves strength and long-term durability for on- and off-road use.
• Improved bushings: Polyurethane (PU) bushings replace rubber to offer better low-temperature performance and firmer handling on rough terrain.
• Pre-greased ball joints: Ball joints are pressed in and pre-greased so they are ready to install without immediate lubrication needs.
• Installation guidance: Includes left and right control arms and a note that wheel alignment is necessary after installation to preserve handling.

Who It's For

This product suits 4Runner, FJ Cruiser and Lexus GX owners who want a durable OEM-style replacement that also raises vehicle height by 2-4in. It appeals to off-road enthusiasts who prefer improved handling from PU bushings and a more robust tubestyle arm over stock stamped parts.

Drivers who plan to change shock absorbers as part of a larger lift kit or who need a custom high-clearance suspension should look elsewhere, since these arms are optimized to allow a 2in lift without changing shocks and are intended as a direct replacement rather than a full aftermarket suspension system.

Pros & Cons

Pros

• Solid build quality from tubular alloy steel gives a confident, durable feel under load.
• Pre-greased ball joints and pressed-in installation reduce initial maintenance and speed installation.
• PU bushings deliver improved low-temperature performance and a firmer, more controlled ride off-road.
• Maintains stock wheel fitment while providing a 2-4in lift, making it a practical upgrade for many owners.

Cons

• Requires alignment after installation, so owners must factor that into time and cost.
• Zerk fittings are copper and can snap if over-tightened during grease service, so careful handling is needed.
