Terrafirma TF508 – Front radius arms, 3° caster correction

Terrafirma TF508 front radius arms provide 3 degrees of caster correction for vehicles with a 2–3 inch (50–75 mm) suspension lift. Lifting a coil-sprung vehicle with live axles changes the caster angle and can cause vague steering and reduced self-centering. These arms help restore positive caster and the steering geometry.
