Our catalog is designed specifically for the 1984–1987 Turbo Buicks, with a particular focus on the legendary ’87 Grand National. We don’t deal in generic listings or universal parts. Every item in our inventory has been handpicked, tested, and tailored for GN performance and restoration.
You’ll find everything from engine components, turbo upgrades, and fuel system parts, to interior trim, weatherstripping, and emblems, all backed by decades of technical expertise. If it bolts, clips, clamps, glues, or connects to a Buick GN, we probably have it—or can tell you how to get it.
Exclusive Products You Won’t Find Anywhere Else
One of the reasons our Buick Grand National parts catalog stands out is our line of Kirban Performance exclusives. These are restoration-grade parts and accessories we’ve developed based on our deep experience with Turbo Buicks and feedback from real-world enthusiasts.
From our polished billet vacuum blocks and custom underhood dress-up kits, to exact-match engine decals and correct-style wiring harnesses, we’re constantly creating better solutions for common restoration pain points.
If you’ve ever been frustrated by the quality or fitment of aftermarket GN parts, rest assured, our catalog only features parts we trust on our own cars.
Body Restoration? We’ve Got You Covered, Literally
Restoring a Grand National’s iconic look isn’t just about the engine, it’s about the lines, the gloss, and the trim. That’s why we carry top-quality solutions for bumper and panel repair.
Need to repair cracked or aging bumper ends? We stock premium plastic filler for car bumpers that works seamlessly with Grand National materials. This isn’t your off-the-shelf filler, it’s professional-grade and designed to bond and flex with factory plastic components.
We also offer body filler for plastic bumpers that’s ideal for contouring and finishing the front and rear bumper covers without cracking or shrinking over time. Combine that with our reproduction bumper fillers, molded to factory specs, and you’ve got the perfect solution for returning your GN to showroom shape.
More Than a Catalog, It’s Your GN Restoration Companion
Every product listing in our catalog comes with expert insights, fitment notes, and, when needed, installation guidance. That’s because we’re not just parts sellers—we’re GN restorers ourselves. We’ve spent years tearing down, building up, and perfecting these cars. And we’re here to help you do the same.
Need technical advice? Have a question about compatibility? Our team is just a phone call or email away. We know that restoring a Grand National is a personal project—and we treat it with the same care and passion that you do.
