Curt Class 4 Receiver Hitches offer advantages that the competition cannot match! All Curt Class 4 hitches meet or exceed SAE standards. Works great with trucks that are lifted higher than stock height due to oversize tire, wheels, or springs. Curt's weathertite construction features closed-end main bodies so dirt and water cannot enter receiver hitch which prevents rusting from the inside out. Precision robotic welding ensures Curt Hitches have superior strength and fit and features a twist-resistant steel tubing. Curt's powdercoating process is second-to-none. Curt mechanically de-scales their steel and subjects it to an extensive washing system before applying the optimum thickness of powdercoating. Curt is so confident in the quality of their receiver hitches that they back them up with a limited lifetime warranty and 1-year finish warranty. No drilling required for installation unless otherwise noted.
