Description

The UMI Stage 1 kit enhances handling while preserving the classic muscle car aesthetic. It includes UMI front and rear sway bars, UMI springs (2-inch lowering for ABF401-2-B), and Bilstein shocks. All components are made in the USA. Engine compatibility: Small block motors, certain big block engines with aluminum heads/intake, and lightweight LS engines (may require front spring trimming). Full-weight big block engines might see a slight 1/4" front end drop.
