Ringbrothers tackled not one, but two Mopar builds for the 2017 SEMA show. Of the two custom Mopars built, we had high expectations for the 1972 AMC Javelin AMX, and we must say, the shop didn’t disappoint.
Not only does the Javelin AMX “Defiant!” look properly badass, it boasts over 1,000 horsepower thanks to its 6.2-liter supercharged Hellcat engine. The company says it’s the most extreme custom car it has ever built.
So, where did it all begin? The Ring brothers sourced the car seen here from their hometown in Wisconsin, which had run around the city for decades. With 12 months to build the car, the shop got to work. Digital design tools helped bring the custom body panels to life quickly inside the shop and the team moved the wheelbase forward six and a half inches. The wheel arches were beefed up to match the massive carbon-fiber hood, new front fenders and grille. Additionally, the taillights, bumpers, trim and engine bay accessories were all machined out of aluminum and custom made for the 1972 Javelin AMX.
Though it’s a Mopar through and through, underneath is a lot of Chevrolet. The sub-frame, by Detroit Speed, was originally engineered for a Camaro, but it matched perfectly to the newly extended wheelbase. Modern engineering touches such as rack and pinion steering, sway bars and RideTech shocks help keep the Javelin poised. Ringbrothers then bolted a Chevy 12-inch rear end with a custom four-link suspension.
Under the massive hood sits the aforementioned 6.2-liter Hellcat engine, which makes 1,036 hp in this application. The massive power bump largely comes from a 4.5-liter Whipple supercharger bolted on. To handle the power, the company installed a Bowler automatic tranmission, and a QA1 carbon-fiber driveshaft, while a new Dodge Hellcat radiator and fan assembly ensure perfect running temperatures.
Finally, to top it all off, Ringbrothers’ finished the AMC Javelin “Defiant!” in a wonderful BASF Glasurit color named “Jalop Gold.” It absolutely suits the car.
Although Ringbrothers debuted its 1969 Dodge Charger yesterday, the 1972 AMC Javelin is absolutely the star of the show. And just look at it—the build absolutely earned it.
