The Tekno RC TKR5049A Aluminum 6.8mm Pivot Ball Set is a precision-machined upgrade designed to improve suspension efficiency and reduce overall weight while maintaining strength and durability in demanding RC conditions. These pivot balls are commonly used in sway bar links and shock rod ends, providing smooth articulation and minimizing slop for more consistent handling and responsiveness. Each set includes four aluminum pivot balls and is fully compatible with a wide range of Tekno RC 1/8-scale platforms, including the EB48 series (EB48, EB48.2–EB48.4, EB48SL), ET48 series (ET48, ET48.2–ET48.3), NB48 series (NB48, NB48.2–NB48.4), NT48 series (NT48, NT48.2–NT48.3), as well as the SCT410, SCT410.3, and MT410/MT410 2.0, making it an essential replacement or tuning component for maintaining precise suspension geometry and reliable performance.
