This special long king pin ball set is designed to optimize the front suspension performance of Kyosho Mini-Z MR-03 chassis models. Crafted from high-strength, hardened steel, these precision-engineered components replace the standard king pin balls, providing enhanced durability and smoother suspension articulation. They are crucial for fine-tuning front-end geometry, allowing for improved handling characteristics and enabling compatibility with various optional suspension knuckles and upgrades within the MR-03 platform.
