The kit is equipped with Bilstein B6 Performance shocks for superior control. Available in red or black powder coat, the Stage 3 kit is proudly designed, tested, manufactured, and raced in our Philipsburg, PA shop in the USA. Spring notes: The springs are designed for Chevrolet small block engines, may require trimming for lightweight LS engines, and may cause a 1/4" front end drop for full-weight big block engines. The springs aim to sit level but may need occasional trimming due to varying weights and preferences.
