Collection: OBS 1500 Lowering Kits and Static Drop Parts

Shop OBS suspension parts for 1988-1999 Chevy & GMC C/K1500 GMT400 trucks — drop spindles, lowering coils, shackles, and flip kits built for a clean, static stance without air ride. Every kit is matched to correct OBS truck geometry for a safe, predictable ride.

Going bigger on C/K2500 or C/K3500? See our 2500/3500 lowering kits. Want adjustable ride height instead? Check out 1500 air ride suspension. Pair your drop with the right OBS wheels and finish the build with OBS billet parts for the interior and exterior.
