This is a set of four optional XRAY 8.4mm Hard Coated Aluminum Pivot Balls, and are intended for use with the XRAY NT1 and NT1 2009 Spec. For serious racers conscious of weight savings, XRAY’s CNC-machined 8.4mm dia. mounting pivot balls are made from premium lightweight 7075 T6 aluminum. A single alu pivot ball is 63% lighter than the steel counterpart, with a total combined weight saving of 18.8 grams! Precision machined to the tightest tolerances using premium fully-automatic German CNC-machines. High-quality hardcoating is done at XRAY's own in-house fully-robotic hardcoating line, ensuring a perfect hardcoated surface every time. Post-hardcoating black finish provides a stylish look.
NOTE: It is recommended that #106230 HUDY Bearing Oil, or other light oil lubrication is used on the threaded posts of the #337251 aluminum pivot balls when installing them into V2 arms.
