Why shop an OBS-specific parts store

GMT400 trucks share a body style from 1988 to 1999, but brake, wheel, and suspension parts change by model and drivetrain: 5-lug, 6-lug, and 8-lug bolt patterns, 2WD (C) and 4WD (K) front ends, and 1500, 2500, and 3500 weight classes. We organize the catalog around those differences so you can shop by your truck instead of guessing. Learn more about OBS Revival Parts, read customer reviews, or shop OBS parts by brand.
