Add the ability to change camber and caster to your Audi or Volkswagen with SPC's adjustable control arms. These arms replace the factory non-adjustable arms, allowing easy on-the-car adjustability after installation. Engineered for both street and track use, the 6061-T6 aluminum ends feature large 18mm threaded steel adjusters to ensure this is the strongest arm set available. Maintenance free ball joints and bushings provide factory levels of noise, vibration, and harshness (NVH) while also giving long service life. Order SPC #81371 for the left side, #81372 for the right side, or #81373 for the complete front end kit. This kit also comes with a replacement knuckle pinch bolt to ease installation as the factory bolt is often frozen in place and must be cut out when replacing the upper control arms. This bolt is also available separately under SPC #21040.
