Have slop in your steering?  Has your lower u joint wore out?  We set out to solve this, and worked with a company that makes steering components for NASCAR.  These high quality u joints are made specifically for the Z3 BMW chassis.  These u joints use caged needle bearings with a slight preload to completely eliminate backlash.  The bearing trunnion is a single piece of hardened chromevanadium tool steel. The grease seals are high-durometer fluorocarbon o-rings in compression against the end surfaces of the needle bearing cups. This means the seals will resist sustained ovenlevel heat and will retain the bearing grease under severe conditions.
 
*Fits all Z3 models
**Off-Road use only

**PLEASE NOTE: To be able to achieve the most direct steering feel, our u joints are precisely machined to have the least amount of play.  The OEM u joint uses a pinch bolt, making the tolerances a lot larger when installing.  Our u joints use set screws and the tolerances are a higher to reduce any slop in the steering.  Please make sure your splines are cleaned and not marred up.  You may need to tap the u joint on with a rubber or dead blow hammer.  Please do not use a metal hammer to hit the steering shaft on.  If for any reason you can not get the u joint on, do not force, and email us at info@racegerman.com
