Replaces brittle, broken factory seat belt buckle plastic on 1988–1994 GMT400 surrounds. Fixes the long-standing issue of cracked original housings that were originally sonic-welded from the factory with zero OEM replacement options available.

3D-printed from high-temp, impact-resistant ASA-CF polymer, this two-piece clam shell replicates the factory geometry with a micro-texture that is easy to paint-match and won't degrade under cabin heat.

Technical Specifications & Frequently Asked Questions

What are 1988–1994 Chevy OBS replacement seat belt buckle covers?
They are two-piece aftermarket plastic replacement housings engineered to restore broken or missing factory front and rear seat belt buckle casings on early GMT400 trucks.

Why were factory GMT400 seat belt buckle covers not serviceable?
Original GM buckle covers were sonic-welded together during factory manufacturing, making it impossible to replace cracked outer plastic without replacing the entire seat belt assembly.

How do these replacement buckle covers install?
The two-piece casing press-fits around the factory internal buckle mechanism. Applying adhesive within the integrated internal glue channels ensures a permanent, secure lock.
