Product Description

The Pedders PED-814109 eXtreme XA Suspension Kit is a comprehensive handling upgrade for the 2015-2021 Ford Mustang S550, combining the acclaimed PED-162099 coilover kit with the PED-814098 front and rear adjustable sway bar system. The coilovers feature 30-position adjustable damping, a fully threaded mono-tube body, and alloy steel motorsport springs rated at 6 kg/mm front and 14 kg/mm rear - delivering a tunable setup capable of serving both daily street use and weekend track duties. Factory-style bracketry and pre-assembled camber plates with roller bearing perches make installation straightforward without sacrificing alignment adjustability.

The included 35mm front and 25mm rear tubular sway bars are engineered specifically for the S550 platform to reduce body roll and sharpen cornering response without adding harshness to the ride. Manufactured using cold-forming and CNC techniques, the sway bars install with all necessary hardware and bushing lubrication included. This kit is not compatible with MagneRide-equipped Mustangs, and strut tower holes may require widening to utilize full camber adjustment. For performance-focused Mustang owners seeking a complete, engineered suspension solution in a single package, PED-814109 delivers a balanced and tunable upgrade.
