Suspension lowering or lift 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 joint bearings. These arms feature high strength tubular steel alloy construction to withstand extensive loads and harshest driving conditions. The harden rubber bushings and pillow ball bearings equipped also provide significantly better handling response over the factory components.
