4Runner 5G ALUMINUM Rear Link Kit

The 4Runner 5G Aluminum Rear Link Kit replaces the weak factory upper and lower control arms with polished 7075-T6 aluminum links, correcting rear suspension geometry after a lift. Double-adjustable ends let you set caster, pinion angle, and axle centering across nearly any lift height, and the aerospace-grade aluminum sheds weight while shrugging off trail impacts. It is a direct rear-link upgrade for the 5th-gen Toyota 4Runner and its platform siblings.

Key Features

• Two 2.0" OD 7075-T6 polished aluminum lower links and two 1.5" OD 7075-T6 upper links
• Double-adjustable ends with right- and left-hand threads for on-vehicle length changes
• Rock Krawler Krawler Joints: 1.25"-12 tpi lowers and 7/8"-14 tpi uppers for high articulation
• 7075 aluminum has memory and returns to straight after a hit, where steel stays bent
• Machined wrench flats for easy jam-nut adjustment and a clean finished look

Fits the 2003+ Toyota 4Runner (4th and 5th gen), 2007+ FJ Cruiser, 2008+ 200-Series Land Cruiser, and 2003+ Lexus GX. Designed to correct geometry on lifted vehicles.

Frequently Asked Questions

Which vehicles does this rear link kit fit?
The 2003+ Toyota 4Runner, 2007+ FJ Cruiser, 2008+ 200-Series Land Cruiser, and 2003+ Lexus GX.

Do I need a track bar too?
Yes, on a lifted vehicle. This kit includes the four control-arm links only. A matching aluminum rear track bar re-centers the axle and is sold separately, or step up to the Link Kit with Track Bar bundle.

Why aluminum instead of steel?
7075-T6 aluminum is lighter and has a material memory, so after a hard hit it returns to its original straight shape rather than bending permanently like steel.

Will these work at any lift height?
The double-adjustable ends allow length changes across nearly any lift height, letting you correct pinion angle and axle position as needed.

What else do I need?
Springs, shocks, limit straps, sway bar extensions, and brake lines are not included and are sold separately based on your build.
