Want to turn more easily on your Metroboard 41″ Electric Longboard? Swap out the inner (deck side) cylindrical bushing on your Caliber II Reverse Kingpin Trucks with these conical bushings, and experience a much tighter turning radius along with more responsive carving. Recommended for riders under 180 lbs who find the standard cylindrical bushings a bit too stiff. Not recommend on our shorter boards or for heavier riders which might find the ride too wobbly. Includes two conical bushings along with two smaller cup washers (for use with conical bushings). One set is enough for both trucks.
