Roush 2015-2026 Mustang Single Adjustable Coilover Suspension Kit (#421839)
Unlock the true handling potential of your S550 or S650 with the Roush 2015-2026 Mustang Single Adjustable Coilover Suspension Kit (#421839). This kit is the perfect bridge between daily street comfort and aggressive track performance. Developed through thousands of miles of testing on the track and the street, this system allows you to lower your Mustang’s centre of gravity while fine-tuning the ride stiffness to your exact preference.
The kit features stainless steel shock bodies for maximum corrosion resistance and longevity. The single-adjustable design lets you adjust rebound damping with a simple turn of a knob, transitioning from a compliant street ride to a firm, planted feel for weekend autocross or track days. With adjustable spring seats, you can customise your ride height to achieve the perfect “staggered” stance, improve cornering grip, and reduce body roll.
Performance Features:
-
Customizable Ride Height: Adjustable perches allow for a significant drop to lower the centre of gravity.
-
Rebound Adjustment: 1-way adjustable damping to tune the suspension response to your driving style.
-
Track-Bred Performance: Developed to reduce brake dive and improve lateral stability during high-speed cornering.
-
Premium Construction: Stainless steel housings and powder-coated performance springs for extreme durability.
-
Compatibility: Engineered to fit both 2015-2023 (S550) and 2024-2026 (S650) Mustang platforms (Non-MagneRide models).
