Buick Gran Sport Parts & Accessories

The Buick Gran Sport was the performance package that launched the muscle car era, appearing on the 1965 Skylark with a 401 cubic inch V8 before evolving into its own model line. Parts for the Gran Sport cover exhaust upgrades, suspension components, and cold air intake systems for performance builds.

Popular Upgrades

Performance headers and dual exhaust systems from Hooker Headers and Flowmaster are the defining Gran Sport upgrades, maximizing flow from the Nailhead and later 400 or 455 V8 engines. Front and rear sway bar kits and lowering springs improve handling without altering the iconic stance.

What exhaust fits the Buick Gran Sport?

Performance headers from Hooker Headers and cat-back exhaust systems from Flowmaster and Edelbrock are compatible with Gran Sport V8 engines including the 401 Nailhead, 400, and 455, delivering better exhaust flow and a classic muscle car sound.

How do I improve handling on the Buick Gran Sport?

Lowering springs, adjustable shock absorbers, and heavy-duty sway bars are the most effective suspension upgrades for the Gran Sport's A-body platform, improving cornering precision and reducing body roll for both street use and show builds.
