Material Quality: 2-4" Lift Front Upper Control Arms is made of high-quality materials, with high durability, perfect matching and strict quality control standards to build and test. The outer diameter of the pipe is 1.5 '' (38mm), and the wall thickness is 0.16 '' (4mm). Sufficient Safety：Welding mainly adopts TIG process, and the safety performance has been more enhanced. 2-4" tubular control arms the previous rubber bushing with the current PU bushing, which is more suitable for low temperature; Hardness 85A MDI PU Bushing for better wear-resistance and strength,reasonable structural design provides better performance for off-road driving. Easy to Install: Replacement Upper Control Arm Suspension Kit 2-4" Lift, Ball joint do not require additional grease; after greasing the threads or bolts, tighten the bolts in either direction.The lock should not be over-tightened; please pay attention to the alignment after installing the arm. Features: These front upper control arms are a direct fit and will work on trucks that are have leveling kits, or lift kits，These front upper Control arms are designed to provide superior strength over factory while correcting ball joint angle and castor for vehicles lifted 2-4". 2-4" lift Front Upper Control Arms for 2003-2022 Toyo-ta 4Runner, 07-14 FJ Cruiser,03-09 Lexus GX470,10-21 Lexus GX460 Compatibility with: 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 Toyota 4Runner 2007 2008 2009 2010 2011 2012 2013 2014 FJ Cruiser 2003 2004 2005 2006 2007 2008 2009 Lexus GX470 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 Lexus GX460 E-coating increases corrosion resistance and prolongs service life. High strength steel body, more stable operation. All components are rigorously tested to provide reliable replacement. High-quality Rubber Our products use high-quality rubber with better oxidation resistance. It can not be denatured and broken at low temperature and high temperature PU Bushing and TIG Weilding The PU bushing instead of rubber bushing, improve maneuverability and Service life, and more suitable for harsh high and low-temperature environments The pin of the ball joint made from the heat treated alloy steel, more stronger and durable E-coating E-coating increases corrosion resistance and prolongs service life. High strength steel body, more stable operation. Advantage and Upgraded Copper The tubular part is made of high-quality cold-drawn steel pipe, which is helpful for chassis correction after the vehicle is lifted . Power-coated Surface, wear-resistant and corrosion-resistant is better than paint, more suitable for an outdoor environment. Direct Replacement Equipped with a protective cover to prevent silt from entering ball joint, extended using life Pre-installed dust boot shields socket components from wear-causing contaminants,exceeded the factory Ball Joint do not require additional grease; after greasing the threads or bolts, tighten the bolts in either direction.
