SPC Performance 81351 Uca'S Audi And Vw - Left

The SPC Performance 81351 is a two-arm adjustable front upper control arm kit for the left-hand side of Audi B5/B6/B7 and C5 platform vehicles, including select VW models. This kit directly replaces the factory fixed-length upper links with precision-engineered, fully adjustable arms that allow up to ±1.5° of front camber and/or caster correction — ideal for restoring proper alignment after a suspension lift or lowering, or for dialing in performance-oriented angles for street or track use.

Constructed from forged 6061-T6 aluminum, these arms deliver maximum structural strength while keeping weight to a minimum. OE-style maintenance-free booted ball joints and bonded rubber bushings preserve factory ride quality, handling feel, and noise, vibration, and harshness (NVH) characteristics.

Due to Audi's unique multi-link suspension geometry, these platforms produce a "Virtual" SAI. Audi does not publish a factory caster specification; SPC recommends targeting 5° to 6° of caster for optimal straight-line tracking and steering return-to-center feel.

Key Features:

• Forged 6061-T6 aluminum construction for maximum strength at minimum weight
• ±1.5° adjustable front camber and caster correction
• OE-style maintenance-free booted ball joints
• Bonded rubber bushings for factory-level NVH performance
• Large 18mm threaded adjuster links for precise, repeatable adjustment
• Replacement pinch bolts included
• Estimated installation time: 0.7 hours per side
• Requires 1 kit per wheel position

This kit covers the left-hand (LH) side only and includes two arms. For the right-hand side, order SPC #81352. To replace both sides, use SPC #81353. Replacement ball joint boot kits are available separately as SPC #81354.
