Product Description

The Old Man Emu UCA0021 is a set of front upper control arms for the 2023+ Toyota Tacoma (4th Gen), 2024+ Toyota Land Cruiser 300 Series, 2024+ Toyota Land Cruiser Prado 250, and 2024+ Lexus GX 550 -- all sharing the TNGA-F platform with independent front suspension. When a suspension lift of 2–3 inches is installed on these IFS vehicles, the factory caster and camber are pushed outside the OE adjustment range, leading to poor alignment, accelerated tire wear, and compromised handling. The UCA0021 brings the alignment cams back into an acceptable range, providing +2.5 to +3.5 degrees of caster correction and -1.5 degrees of camber based on a 2-inch lift.

The tubular steel design features forged eyelet and ball joint housings for maximum strength under off-road stress, a heavy-duty greaseable ball joint with protective cap for long service life, and free-pivoting GIIRO bushings that require zero grease and zero maintenance for the life of the arms. Mount provisions for OE ABS lines ensure clean, factory-quality routing of brake sensor wiring. Bolt-on installation with no cutting or modification required -- strongly recommended with any 2–3" front suspension lift to maintain proper front-end geometry. Compatible with OME BP-51, MT64, and other aftermarket suspension systems. For the 2005–2023 Toyota Tacoma (3rd Gen), use OME part number UCA0005 instead. Designed and manufactured in Australia by ARB/Old Man Emu.
