Steeda Mustang EcoBoost/V6/GT Stage 2 Drag Pack (2015-2026)
Steeda's S550/S650 Drag Pack for 2015+ Mustangs is the ultimate suspension kit for the drag strip. Featured on Steeda's 2018 world-record-setting, 10-second Mustang GT, this kit ensures your Mustang stays firmly planted for a more powerful launch by preventing the wheel hop common when launching an IRS-equipped Mustang.
The kit includes the Alignment Dowel Kit to square the rear subframe to the chassis, the Differential Bushing Insert System (urethane inserts that require no permanent modification and install in under an hour) to minimize pinion angle changes and eliminate differential deflection, TIG-welded and powder-coated Adjustable Rear Toe Links with over an inch of adjustment, CNC-machined Vertical Links with Delrin bushings that won't flex under load, and Billet Rear Shock Mounts with a spherical Teflon-lined bearing that won't deteriorate under aggressive launches while providing extra clearance for wider rear tires.
Note: Will not fit 2024+ Mustangs equipped with Brembo brakes.

555-4121 - Steeda Billet Aluminum Vertical Links with Delrin Bushings
