OEM Mach 1 Handling Package Spring Kit (Front & Rear)
for Ford Mustang 2018-23

Manufactured by Ford | Part #JR3Z-5560/KR3Z-5310

Upgrade your suspension with the optimum Ford Performance OE Handling Package Spring Kit originally designed for the Mach 1 Mustang.

The Mach 1 Handling Package is a significant upgrade over the already impressive Mach 1 platform.

The handling package utilises the same shocks & struts featured on the Mach 1, however the upgraded springs have a stiffer spring rate making for better handling at top speeds when pushing the car to the limits on the track.

It also offers improved styling with a more aggressive track stance.

Please bear in mind that stiffer springs does sacrifice some of the ride comfort of your car, however the effects are minimal when compared with the benefits for real performance-hungry handlers. These springs are Magneride compatible.
