With this product, you get a pair of UMI Performance upper spring mount weight jacks, designed specifically for the 1982-1992 GM F-Body platform when used with a UMI K-member. These weight jacks offer a straightforward bolt-in solution to precisely adjust your vehicle's ride height and fine-tune its corner balance, which is crucial for optimizing handling on the street or track.
