Beech Bend’s Best at the Tri-Five Nationals 2025
This year marked 70 years since the 1955 Chevy hit the streets, kicking off a three-year run that forever changed the automotive landscape. And judging by the rows of spotless Bel Airs, hardtop sedans, wicked gassers, and full-tilt pro-touring machines, the legend is alive, well, and meaner than ever. Everywhere you turned, there was another masterpiece—whether it was a flawless restoration, a ground-shaking drag car, or a radical custom that pushed the envelope.
WE HAVE A WINNAH!
This beauty is easy on the eyes. It’s lightning-quick on the throttle and a lot of fun to cruise around town in—but it wasn’t always that way.

But this isn’t just an aesthetic upgrade. Each unit features a bold Chevrolet Bowtie Emblem, available in milled and raised or recessed and painted versions, with the option of red or black finishes to perfectly complement your engine bay.

The alternator is factory-tested to ensure it meets rigorous quality standards and is shipped with a unique verification sheet, offering peace of mind that your alternator is ready to deliver high output and low idle drag the moment it’s bolted into place.
