Keep your S550 planted and put power to the ground reliably with an upgrade to your half shafts. The Ford Performance half shafts are built stronger and are updated to help take your Mustang to new levels. If your Mustang has a power adder or sees use on the track, the Ford Performance half shafts are a great upgrade.

The Ford Performance half shafts are built tougher to combat wheel hop so that you can launch your Mustang more reliably and cut down those 60-foot times. When launching your S550 at the track, you may find that you are experiencing wheel hop; a repeated loss of traction and regained traction that causes the wheels to 'hop' and suspension to deflect. This results in a harsh launch and violent shaking/jumping. The Ford Performance half shafts work to correct this so that you can launch your Mustang quicker and cut down those times.

CNC machined components for a precise part and exceptional quality. The half shaft is CNC machined from aerospace high-alloy materials and features severe-duty serviceable CV joints with billet centers. The resulting half shaft is built to last and can handle hard launches at the track and get the power from the Coyote engine to the ground.
