Dialed 2/4 Drop for 1988–1991 OBS Silverado & Sierra

A proper OBS stance starts with the right setup, and this Slamrite 2"/4" Drop Kit is built specifically for 1988–1991 Silverado and Sierra 1500 2WD models. It delivers a clean, level drop that improves both appearance and road feel without sacrificing everyday comfort.

The front is lowered using 2" drop spindles, helping retain factory suspension geometry for smooth steering and consistent ride quality. In the rear, a 4" drop with shackles and hangers finishes the look, bringing the truck down evenly for a more aggressive profile.

All components are made from heavy-duty steel, ensuring durability and reliability whether the truck is driven daily or built for weekend cruising. With a straightforward bolt-on design, getting your OBS sitting right is simple and effective.
