Product Description

The Old Man Emu UCA0004 upper control arm kit is designed to restore proper front-end geometry on lifted Toyota 4Runner, FJ Cruiser and Lexus GX platforms. When a front lift is installed, caster and camber often move beyond factory adjustment limits; the UCA0004 brings them back into spec, improving steering control, tyre wear and suspension travel.

With forged ball-joint housings, heavy-duty greasable joints, and maintenance-free GIIRO polymer bushings, these arms deliver long-lasting durability for on- and off-road use. They retain ABS/brake line mounting locations for direct compatibility, and the black powder-coat finish provides excellent resistance to corrosion. Ideal for vehicles using moderate front lifts (~2") and aftermarket components, the UCA0004 ensures alignment capability and improved front-end behavior without major chassis modification.
