XRAY 337251 Lightweight Aluminum Pivot Ball Set 8.4mm  [XR-337251]

Track-Focused Pivot Balls for Improved Handling

RC hobbyists chasing tighter lap times will value the XRAY 337251 Aluminum Pivot Ball Set as a direct upgrade. These pivot balls are CNC-machined from premium Swiss 7075 T6 aluminum to combine high tensile strength with a significant reduction in rotating mass.

Reduced Mass with Precise Build Quality

Each of the four pivot balls in this kit is engineered to be about 63% lighter than the equivalent steel part, saving roughly 18.8 grams in total. That lower unsprung and rotating weight helps with quicker direction changes and crisper steering feel on race circuits.

Controlled Production and Durable Finish

Machining is carried out on high-precision German CNC equipment to hold tight tolerances, and each piece receives a hardcoat in XRAY's automated finishing line for a durable black surface that resists wear and looks clean on the car.

Built for competitive drivers who want to trim mass without sacrificing strength, the XRAY 337251 set sharpens handling and responsiveness for demanding track use.
