It's a well-known issue that BMWs come equipped with weak front thrust arm bushings that are prone to failure. The original rubber bushings are engineered to permit significant fore/aft movement of the rear wheels and are filled with fluid to absorb road impacts. While this compliant design enhances daily driving comfort and contributes to the luxury feel of your BMW, it also adds to the sense of detachment and numbness that many enthusiasts lament in modern BMWs. Moreover, the OEM design falls short of meeting the needs of street or racing enthusiasts seeking optimal handling and braking performance. The constant twisting and deflection demanded of the rubber bushings often lead to premature failure, resulting in compromised handling, wheel shimmy, delayed steering and braking responses, undesired changes in alignment, and uneven tire wear.

Announcing the debut of the Turner Front Thrust Arm Ball Joints! Turner engineering team embarked on a mission to create a solution that surpasses OEM standards in durability without necessitating any modifications. The result? A product that delivers almost instant cornering and braking response, enhancing road feel and driving pleasure to the maximum. The control arm monoballs incorporate a sealed OEM BMW ball joint, guaranteeing exceptional quality and longevity. Crafted with precision CNC machining from 6061-T6 anodized aluminum, the bearing assembly boasts a knurled outer diameter for a flawless press fit and unparalleled durability, ensuring the longest possible component lifespan.

By utilizing a sealed ball joint, Turner achieved the ultimate in terms of low friction no bind suspension travel with no unwanted deflection, providing exceptional steering precision, turn-in response, and direct braking feedback; all while maintaining exceptional comfort and durability levels making these an excellent no compromise upgrade even for a street car. These thrust arm monoball / ball joints are a must have for any track car, but are also completely street-able and are a great upgrade for any enthusiast that enjoys spirited driving.

We offer these these front thrust arms with the monoball bushings pre-installed for your convenience. Since BMW recommends the thrust arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms. (ES4061572)
