Suspension lifts cause axle housing to rotate. This not only affects suspension articulation but also results in poor driving stability and vibrations due to altered caster and pinion angle. Adjustable arms help set axle to factory alignment spec for greater handling performance and lifespan on the propeller shaft u-joint bearings. The arms are well-known for high strength steel tube construction to withstand harshest off-road conditions. They also feature harden rubber bushings for better handling response over the factory components.. Correct caster & pinion angle on lifted cars. High quality ultra strong steel construction. ED coated and painted for the highest durability. Equipped with premium quality harden rubber bushings  Note: Harden Rubber Equipped 2 PCS/SET  Fits: Toyota Land cruiser J80 1990-1997 / J105 1998-2007 Lexus LX 1st LX450 J80 1995-1997
