Ultra-Fab Ultra 4" Swivel Skid Wheel for Travel Trailers - 2-Pack

Ultra-Fab Ultra Swivel Skid Wheels help prevent tail dragging and digging while backing up and help protect the undercarriage from damage. They have extra strong metal wheels with roller bearings & 0.25” urethane on outer edge. The drop forged caster is superior in strength to other casters. Bolts and lock nuts are provided to bold the casters to the mounting plates. Welding the mounting plates to the frame is usually best, but additional reinforcement is sometimes required. Included are two 4” skid wheels, two mounting plates, eight 3/8” lock nuts, eight 3/8-16 x 1” bolts, four ½” lock nuts, and four ½-11 x 1 ¼” bolts.
