Replacing Your ’88-’99 OBS Chevy Or GMC GMT400 Side Body Molding

There's a reason the GMT400 dominates the custom and restoration truck scene.

The GMT400 - better known as the OBS (Old Body Style) Chevy and GMC, spans the 1988 to 1999 production years. These trucks modernized the pickup market with their sleek, aerodynamic lines. Whether it's a 454 SS muscle truck, a lifted Z71, or a bagged street cruiser, the style of the OBS is king.

A defining exterior trait of an OBS Chevy is the thick molding strip running cleanly from fender to bedside. Over time, the chrome delaminates and the black rubber turns gray. The solution? Replace your old, chalky, deteriorating, or missing trim with All-Fit's '88-'99 OBS Chevy and GMC Body Side Molding - it's the ultimate finishing touch.

How To Install Chevy Truck Body Side Molding

You don't need to pay a professional body shop or buy out any specialized tools to install new body molding yourself. Our no-drill body side molding is a straightforward driveway DIY task that takes less than an hour. Here's how to get a flawless fit:

1. Surface Preparation is Everything: The secret to a permanent, solid bond is a surgically clean surface. Use a mixture of isopropyl alcohol and water to strip away all old wax, road grime, and grease from the mounting area. Prep is the lion's share of the job - giving the adhesive a clean surface allows the molding to adhere without issue.

2. Tape It Off and Line It Up: Whatever you do, don't just eyeball it. Lay down a straight line of painter's tape across your body panels to act as your guide so your new adhesive car door protector tracks perfectly level from the front fender all the way back.

3. Peel, Stick, and Press: Start at one end and peel back just a few inches of the protective adhesive backing. Firmly press the molding onto the body, tracing right along your tape line. Just keep peeling the backing, aligning the trim, and applying steady pressure until the entire strip is pressed down tight.

Keep Your Emblems Or Go Badgeless

One of the biggest perks of All-Fit Body Side Molding is the versatility. You can easily re-mount your original factory emblems right over the trim to keep a period-correct look. If you prefer a sleeker profile, leave the badges off entirely for a clean, custom look.
