Product Details

Turners experience with spherical front control arm ball joints go back to those they designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011). Turner wanted to offer e30, e36, and e46 owners similar levels of handling precision and control for the track and street, but weren’t satisfied with the other options out there. Instead of a Delrin® bushing or unsealed spherical bearing alone, we selected an oversized sealed greaseable spherical monoball to offer unparalleled durability and precision, but designed a Delrin® adapter sleeve to help isolate the added noise, vibration, and harshness that a full solid monoball bearing will have. While race-ready, our hybrid Delrin®/monoball control arm bearings are more at home on the street than other kits that are advertised as “race-only” bearings. Turner did extensive street, autocross, and track testing to ensure the spherical bearing used in this bushing design excelled in each setting.

The stock rubber bushings, even those found in the M3, allow significant fore/aft movement of the front wheels to help absorb road impacts, especially when being pushed hard. This soft flexible design maximizes daily driving comfort, but also allows considerable alignment change. This unwanted deflection stands between you and a crisp, confidence-inspiring driving experience. The advantage of a monoball bearing is that it will not deflect under load, eliminating all unwanted deflection while still allowing complete freedom of movement in the desired angles. What you get is superior steering precision with better handling from more consistent alignment and direct braking feedback, with exceptional service life. Thanks to the Delrin® insert and double lip seals, there's none of the extra noise or reduced service life often found on other spherical bearings.

In short, if you're seeking front control arm bushings that offer precise, predictable handling, crisper braking feel, with a long service life free from noise - look no further. We have you covered.
