Product Details

The best way to describe the performance of these thrust arm bearings is to start by explaining how the stock bushings work on your vehicle. The OE bushing is designed using flexible rubber that houses a dampening fluid to provide a more cushioned driving experience. Over time the bushing will begin to crack from the tension applied primarily under braking flexing the bushing towards the rear stretching the rubber and rebounding towards theĀ front, once the stress has created cracks the bushing will begin to leak taking all of the strength out of the bushing. The common upgrade has always been moving into a non-fluid filled bushing that is still designed from rubber resulting in a lot of deflection instead of smooth natural movement.

The Turner Monoball upgrade provides the advantage of a solid bushing by only allowing the necessary movement and allowing the smooth articulation of the monoball bearing to guide your suspension. This upgrade provides a more precise feel on the road affecting the steering and cornering. The monoball bearing eliminates the deflection from the thrust arm taking the shock out of you suspension under load and out lasting any other replacement option on the market.

This is the perfect upgrade for all types of drivers from track to the daily driver, every driving type has been impressed with the improvement these bearings provide.
