The Detroit Speed Wheel Hub Conversion Kit will convert your 1999-2007 2WD Chevy Silverado to a 5-lug bolt pattern. This will allow you to have more options for aftermarket wheel and brake systems. The DSE wheel hubs have both 5 x 5-inch and 5 x 4.75-inch bolt patterns. The use of high performance hubs results in improved hub stiffness and performance, reduced brake caliper piston knock-back as well as improved hub durability. The wheel hub remains in the factory location and does not affect wheel offset. NOTE: If you have rear disc brakes, you will need to upgrade to 13" rotors, calipers, and brake pads. See the instructions for brake options.
