Poly Performance Uniball Replacement Kits
Poly Performance has saved you time and money by kitting together some common service parts and tools to keep your vehicle on the road. Uniballs have long been an industry standard in high performance mid and long travel components; but like everything else, these spherical bearings wear with time and use and will need periodic replacement. This kit features 2 top quality, teflon lined FK WSSX16T uniballs, and 2 matching heavy duty spirolock style snap rings. The WSSX16 is used on many upper control arms.*
For those looking for a bit more, the All German Motorsports Uniball Tool is the premium choice for shop professionals, those doing race prep, or anyone who plans to keep a vehicle serviced for a long time. This high quality billet tool features chamfers to protect the welds of your uniball cup, and the ball race of the joint itself, centers on the inner diameter of the ball, and can be used
Notes:
- *ALWAYS confirm with the arm’s manufacturer the correct replacement part number, see image for dimensions of WSSX16 Ball Joint.
- These DO NOT fit ICON upper arms.
- Please use TCS-FK-REP-KIT for Total Chaos specific products as their Uniballs have a slightly different spec than a standard WSSX16T
