This replacement pin substitutes the king pin that secures the centre link to the bell crank. By lowering the rotating and reciprocating mass within the steering linkage, the SD-414BA reduces inertia on moving components and can sharpen the initial steering response.
To fit, remove the original king pin connection on the centre link, insert the sleeve and pin according to your chassis assembly guide, and secure using the included screws. After installation, check steering clearance and travel to ensure the linkage moves freely without binding.
