These precision-engineered flanged bushings are essential for maintaining and restoring the critical steering performance of vintage Kyosho Optima series off-road buggies. Positioned within the steering knuckles, they provide a low-friction pivot point for the kingpins, significantly reducing slop and wear in a high-stress area of the front suspension. Crafted from durable brass alloy, these components ensure smooth steering articulation and extend the lifespan of other vital front-end parts, making them indispensable for both competitive racers and meticulous restorers of classic RC models.
