Ringbrothers Turns a Chevy K5 Blazer Into a Bespoke 1,200-HP Off-Roader

Despite only being founded in 2011, Ringbrothers has quickly emerged as one of the world’s most eminent custom car shops, with the Wisconsin-based workshop churning out meticulously-crafted restomods that sport an astonishing amount of bespoke parts and an equally impressive level of attention to detail. And for much of the last year, the Ringbros team has been laboring away behind closed doors in order to produce a whopping four one-off builds for this year’s SEMA Show — one of which is the absolutely stunning Chevy K5 Blazer known as “Bully.”

Born out of more than 8,500 hours of labor, Bully is based on a 1972 K5. The project is constructed around a custom chassis that’s been mated to Currie Dana 44 front and Dana 60 rear axles and a triangulated four-link suspension with two FOX coilovers per wheel. At the heart of the K5 is now a 6.8-liter LS3 V8 equipped with a massive 3.0-liter Whipple supercharger and a Bowler Tru-Street GM 4L80E automatic transmission — a powertrain that now puts down 1,200hp. Other noteworthy performance upgrades come in the form of Baer six-piston brakes at all four corners, a Holley Dominator EFI system, and custom Flowmaster headers and mufflers.

Crafted from carbon fiber, the donor’s exterior has been gifted a one-off hood with machined billet supercharger covers and flared fenders that provide additional space for the project’s increased suspension travel and custom 18” HRE wheels. Alongside its striking custom “Bashful Blue” paint job and custom LED lighting, the exterior of the truck also sports one-off “Ringbros,” “1200HP,” and “Bully” badging — with the latter bespoke emblem also being embedded with a weathered mini baseball bat. The interior of the truck is even more involved, with the cabin sporting fully custom upholstery by Steve Pearson of Upholstery Unlimited, Dakota digital instrumentation, a bed-mounted WARN winch, and a custom Ringbros-branded jerry can.

Ringbrothers’ 1972 Chevy K5 Blazer ‘Bully’ project will remain on display at the SEMA Show for the duration of the event — and will likely be taking home an award or two, if it’s not beaten out by the other trio of builds the shop brought to Vegas this year.
