Restoring the Foundation of the OBS Front End

Restoring the Foundation of the OBS Front End: AMD’s Radiator Support for 1988–1993 GMT-400 Chevy & GMC Trucks

The OBS (Old Body Style) GMT-400 Chevrolet and GMC trucks have become one of the hottest segments in the classic truck world. From daily-driven C/K pickup trucks to fully restored Suburbans and Yukons, these trucks combine timeless styling with modern drivability. But one critical component often overlooked during restoration is the radiator support—the structural backbone of the entire front clip.

Auto Metal Direct’s OBS Radiator Support (Part #350-4088) is designed to restore that foundation correctly.

Why the Radiator Support Matters on OBS GMT-400 Trucks

On 1988–1993 Chevy and GMC C/K trucks, the radiator support does far more than hold the radiator. It establishes:

• Correct headlight and grille alignment

• Proper fender and hood positioning

• Structural support for the front clip

• Accurate placement of the radiator and cooling system

Years of use, corrosion, and minor collisions often leave original radiator supports bent, cracked, or rusted—causing uneven panel gaps, misaligned headlights, and poor front-end fitment. Replacing the radiator support is often the only way to properly correct these issues.

Introducing AMD Part #350-4088 – OBS Radiator Support

The AMD #350-4088 radiator support is an OE-style reproduction engineered specifically for early GMT-400 trucks and SUVs. Built using all-new tooling, this support replicates original GM contours, mounting points, and dimensions to ensure proper fit and alignment across the front end.

This is not a generic replacement—it’s designed for builders and restorers who want the front of their OBS truck to fit and look right.

Why AMD’s OBS Radiator Support Is Different

Unlike many aftermarket radiator supports currently on the market that are advertised as a “one-size-fits-all” solution for 1988–1998 OBS trucks, AMD’s #350-4088 radiator support is a vehicle-specific, OE-style reproduction engineered exclusively for 1988–1993 GMT-400 front-end architecture. Universal supports often compromise fitment by blending early and late OBS design features, which can lead to misaligned headlights, uneven hood gaps, incorrect grille positioning, and unnecessary installation work. AMD’s premium support is built from the ground up using new tooling that follows original GM contours, mounting locations, and structural geometry, delivering significantly better front-end alignment and panel fit. For builders and restorers who care about accuracy, AMD’s radiator support provides a level of precision and quality that generic aftermarket alternatives simply cannot match.
