The QuadBoss Polaris RZR RS1 / XP 1000 / XP 4 Turbo / XP 4 Turbo S Lower Ball Joint Kit is a heavy-duty upgrade designed to prevent premature ball joint failure by replacing the O.E.M. aluminum joint with a robust steel alternative. Engineered with a durable steel case and a POM-M90 bearing cup to isolate the ball end, this kit ensures long-lasting performance and reliable handling. Ideal for both off-road enthusiasts and utility applications, it offers a cost-effective solution for restoring or enhancing lower A-arm performance without needing to replace the entire A-arm or steering knuckle.
