Upgrading your control arms with DELRIN bushings completely eliminates deflection under load and significantly reduces rotational resistance. This enhancement enables the suspension to respond more quickly and consistently, without adding to the spring rate, which is a common issue with bonded rubber bushings that resist rotation. The A3 Speed DELRIN upper control arm kits deliver a substantial upgrade over the stock bonded rubber bushings. Unlike rubber, Delrin does not deflect under pressure and allows free rotation with no resistance. The aluminum cross-shafts included in the kit feature internal grease channels accessed via a user-friendly external fitting, ensuring proper lubrication. Additionally, the Delrin bushings incorporate internal flutes that retain grease, reducing wear and decreasing friction during rotation.
