This ball connector secures a king pin to an aluminium steering block with an ISO 3mm screw thread. The button-head shape keeps the stud profile low to avoid clashes with adjacent steering and suspension parts on touring and on-road RC vehicles.
Compatibility depends on the screw standard and hole spacing of the steering block; this item fits blocks that accept an ISO 3mm screw. Check that the block accepts a button head screw and that the ball seat geometry matches your steering linkage prior to purchase.
Installation is straightforward for experienced modellers: use the correct ISO 3mm screw, attach the ball stud to the steering block, and verify the joint moves freely without undue play. Inspect ball-seat contact and re-torque after initial running; replace the ball if wear or looseness appears.
As a tuning component, the low-profile ball joint can reduce linkage bind and help maintain consistent steering when combined with proper shims and tight king pin assemblies.
