This GPM 7075-T6 alloy upper link bar set is built to improve link stability on the LOSI LMT 4WD Solid Axle Monster Truck without altering the truck geometry. It replaces the factory LOS244013 component and uses an "arcuated" profile to secure the steel pivot ball, reducing the chance of ball detachment during aggressive runs. The description focuses on precision fit and long term serviceability for hobbyists seeking a durable top link upgrade.
