HANDLING KIT LEVEL 3, GM B-BODY; 78-93 GM B-BODY, W/ SHOCKS

Top performance is the desired goal of many automotive upgrades—precisely what QA1 Level 3 handling suspension kits deliver. Compared with the Level 1 and 2 packages, these heavy-duty assemblies offer additional control components, as well as stiffer springs to maximize your cornering ability and handling on average-weight small block and LS-powered vehicles with stock trim. QA1 Level 3 kits are available with or without shocks and struts—giving you the flexibility to obtain the shocks or struts and spring rates you want. Many of these Level 3 bolt-in components are built for race-quality performance, and all will work seamlessly with whatever OEM parts you attach them to.
