Genuine Audi Lower Spring Seat 8K0412103C OEM A4 B8 Authorized Dealer - Audi (8K0-412-103-C)

Genuine Audi Lower Spring Seat is the factory-engineered component that cradles the base of the front coil spring on your Audi A4, ensuring precise spring alignment and consistent ride geometry across the full suspension travel range. Designed to fit Audi A4 models, this OEM lower seat serves as the critical interface between the coil spring and the strut housing, absorbing micro-vibrations and preventing metal-on-metal contact that leads to noise, premature spring wear, and handling instability. Choosing the genuine Audi OEM Lower Spring Seat over aftermarket alternatives matters specifically for this part because spring seat geometry, durometer rating, and material composition are calibrated to factory suspension tolerances. Aftermarket coil spring retainers frequently use inferior rubber compounds that crack, compress unevenly, or shift under load, throwing off camber and caster settings that directly affect tire wear and steering response. The genuine 8K0412103C maintains its engineered profile mile after mile, preserving the handling precision Audi engineers intended. Whether you know this component as a lower seat, coil spring insulator, coil spring pocket, or coil spring retainer, part number 8K0-412-103-C is the correct factory replacement. Audi Henderson is an authorized Audi dealer, and every genuine OEM part purchased through our store is backed by the manufacturer warranty for complete peace of mind.
