SPC 81378 – AUDI BENTLEY ADJUSTABLE CAMBER/CASTER UPPER CONTROL ARM RACING KIT

Part Number: 81378

Summary: The SPC 81378 Adjustable Camber/Caster Upper Control Arm Racing Kit corrects alignment issues by allowing for a camber and caster adjustment of ±1.5°. Featuring xAxis™ sealed flex joints, this kit replaces the factory compliant inner bushings, providing improved handling and responsiveness. The factory arms are insufficient as they lack the necessary adjustability for precise alignment tuning, especially in performance applications.

Features

• xAxis™ Sealed Flex Joints: Free pivoting, minimum compliance joint provides enhanced handling responsiveness to ensure superior performance during dynamic driving conditions.
• Forged 6061-T6 Aluminum Construction: Maximized strength at a minimum weight provides durability and weight savings to ensure optimized performance without excess weight.

• OE Style, Maintenance Free, Booted Ball Joints: Designed for longevity provides minimal maintenance requirements to ensure reliable operation without frequent servicing.
