Are BDS lift kits complete or do I need to purchase other parts?

BDS designs kits to be complete with all required components to correct the suspension, steering, and driveline geometry. Accessories are just that, add-ons to further improve vehicle performance. In a few cases, based on vehicle variations additional components may be available to accommodate the variant, but are listed as accessories. Examples being the factory auxiliary shocks on some 80-96 Fords or carrier bearing drop brackets used on trucks with 2-piece rear driveshafts vs a 1-piece rear.
