1998 GMC Sierra 1500 Sportside

A Sportside bed (also called Stepside) is a pickup truck bed style where the bed is narrower and features a distinctive step or indentation behind the cab on each side. Instead of the flat, slab-sided look of a standard fleet-style bed, the Sportside has those classic curved rear fenders that stick out, making it easier to reach into the bed from the sides.

GMC and Chevrolet used the term “Sportside” for this design, while Ford called it “Flareside.” On your 1998 Sierra, this was actually a less common option compared to the standard wide bed, which is why the seller mentions it’s “harder to find.” It gives the truck that retro, classic truck silhouette that many people love.

Looking at the listing for this particular truck, it’s an Extended Cab with the Sportside/Stepside short bed configuration - definitely a cool combo for an OBS-era GMC!

Is there anything else about this truck or similar Sierra models I can help you with?
