Factory UCAs weren't built for the added height — the result is negative caster, binding at droop, and a ball joint that wears out way faster than it should. RSO Suspension's front upper control arms fix all of that.\u003c\/p\u003e\n\u003cp\u003eDesigned specifically for the Toyota 4Runner (2003–2024) and Lexus GX460 \/ GX470, these UCAs restore proper suspension geometry at lifted ride heights. More ball joint travel, corrected caster, and heavy-duty construction — so your rig handles the way it should, on road and off.\u003c\/p\u003e\n\u003cp\u003eWHY UPGRADE YOUR UCAs?\u003cbr\u003e— Corrects caster loss from 2–4\" of lift\u003cbr\u003e— Restores full suspension travel and droop\u003cbr\u003e— Eliminates ball joint binding at extended height\u003cbr\u003e— Direct OEM bolt-on fitment — no modifications needed\u003cbr\u003e— Built for the rigors of off-road and daily driving\u003c\/p\u003e\n\u003cp\u003eFITMENT:\u003cbr\u003eToyota 4Runner — 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024\u003cbr\u003eLexus GX460 — all years\u003cbr\u003eLexus GX470 — all years\u003c\/p\u003e\n\u003cp\u003eThese UCAs are a staple of the builds we do here at Underdog Motorsports in Mesa, AZ.
