High-quality swing arm 8K0407 509 for all Audi Q5 8R models produced after 2012

This premium left rear upper swing arm is precisely molded 1:1 according to OEM standards and manufactured to match original equipment quality. It is customized for all Audi Q5 8R vehicles manufactured from 2012 to 2017, and also widely compatible with other MLB B8/C7 platform Audi models. We maintain sufficient spot inventory and support flexible small-batch and bulk orders for global auto parts wholesalers and repair workshops.
As an essential front suspension component linking the subframe and steering knuckle, this upper rear control arm absorbs road shocks, stabilizes wheel alignment parameters, and significantly improves driving stability during straight-line driving, braking and cornering.
After long-term service under heavy loads and complex road conditions, original swing arms tend to suffer from cracked aging rubber bushings, worn ball joints and surface rust. These failures cause abnormal chassis knocking noise, steering drift, severe inner tire wear and vague suspension handling. Our upgraded swing arm is equipped with thickened anti-aging bushings and fully sealed pre-greased ball joints to extend service life, gaining continuous repeat orders from aftermarket clients all over the world.
