The community has definitely come together to show support to one of the quickest-growing truck segments to sweep the nation—the OBS ’88-’98 GMT400 platform. For truck enthusiasts of a certain age, it might be hard to come to grips with these pickups being considered the new “classic” trucks but, hey, at least you can say that these were the leaders of the first wave sport truck scene back in the early ’90s. This platform is definitely deserving of its resurgence over the last few years, and we only see signs of it growing.
One major sign of that growth is the sheer number of OBS projects showing up to truck events all over the country. Builders of these trucks are paying homage to the style of the past by modernizing them with products that are currently being designed and manufactured to meet the criteria of today’s custom standards. From radical chassis components, readily available restoration sheetmetal panels, and interior parts to high-performance products and everything in between, there has never been a more exciting time to build a full-size pickup or SUV of this era.
Follow along and start browsing through what we hand-selected from the current OBS aftermarket for your consideration. Surely there’s something here you need right this minute or will soon want to have in the very near future. The height of summer show season is now—don’t wait to place an order for these must-have parts before winter is here.
