SPC Performance 81371 Audi & Vw Control Arms Left

The SPC Performance 81371 is a fully adjustable front upper control arm for the left-hand side, designed to unlock camber and caster adjustability on Audi C6, D3, and compatible Volkswagen platforms. These arms are a direct replacement for the factory fixed-length upper links, enabling precise on-car alignment adjustments after installation without the need to remove the arm.

Adjustment Range: ±1.5° camber and ±1.5° caster — ideal for correcting alignment on lowered vehicles or dialing in suspension geometry for street or track use.

Key Features:

• Forged 6061-T6 aluminum construction for maximum strength at minimum weight
• Large 18mm threaded steel adjuster links for robust, reliable adjustment
• OE-style maintenance-free booted ball joints to maintain factory ride quality and NVH (noise, vibration, and harshness) levels
• Bonded rubber inner bushings preserve factory handling and compliance characteristics
• Replacement knuckle pinch bolt included — factory bolts often seize and must be cut out during upper control arm replacement

This listing is for the left-hand (LH) side only and includes two arms to replace the two front upper links on the left side. For the right-hand side, order SPC #81372. For a complete front axle kit covering both sides, order SPC #81373. The included replacement pinch bolt is also available separately as SPC #21040. Estimated installation time is approximately 0.7 hours per side.
