SPE Motorsport S550 & S650 GT Stage-1 Cradle Lockout Kit

SPE's Stage-1 Cradle Lockout Kit is the foundation fix for S550/S650 wheel hop — it locks the cradle's rubber bushings down so the rear end stops flexing under load.

Features & Benefits

• Billet aluminum upper lockout rings capture the inner bushing sleeve and outer cup lip on the front cradle
• Lower bushing locating washers capture the bottom of the bushing sleeves for nearly zero movement
• Self-aligning design eliminates the need for separate Delrin alignment dowels
• Reduces wheel hop and 60-foot times
• Increases control and predictability
• Adds no NVH; installs with simple hand tools
• Non-permanent modification

Fitment: 2015-2027 Mustang GT; 2016-2020 Mustang GT350; 2020-2021 Mustang GT500.
