Product Description
Coil Spring 6R0411105AD
This component (OE 6R0411105AD) is a front coil spring. It is a key part of the front suspension, supporting the vehicle's weight and absorbing road shocks. Over time, coil springs can sag or break, leading to a lower ride height, poor handling, and a harsh ride. Replacing this coil spring restores the vehicle's ride quality and handling.
Key Features
Platform-Matched Rate (PQ25): Specifically engineered for the PQ25 platform's 1,050–1,150 kg front-axle load range, providing a 36 N/mm spring rate that balances the agile steering response expected in a B-segment hatchback with adequate bump absorption on broken pavement.
Electro-Galvanized Wire: Unlike conventional hot-dip galvanized springs, the wire receives an electro-galvanized coating before coiling, ensuring 100% coverage of the spring's inner surface-a critical area often missed by post-coiling processes.
Controlled-Sag Design: The spring is pre-set (blocked) to 120% of its maximum design load during manufacturing, creating a permanent "memory" that prevents long-term sagging and maintains the vehicle's factory curb height for the life of the component.
Asymmetric End Closure: The upper end features a semi-closed termination while the lower end is fully closed and ground, matching Audi's specific strut design that uses a conical lower spring seat.
Weight-Optimized at 2.5 kg: Lightweight construction reduces front-axle unsprung mass, contributing to the A1's agile turn-in and precise steering feedback.
