7540X Pivot Balls

Traxxas 7540X pivot balls are upgraded steel ball studs that replace the stock plastic pivot balls in the suspension of various Traxxas trucks and crawlers, providing a stronger, more durable connection point for links and arms. Designed to reduce wear and improve steering precision and suspension articulation under heavy use, these pivot balls help maintain consistent geometry and reliability on rigs like the TRX‑4, TRX‑6, and 4×4 slash‑series models.
