2012 Jeep Wrangler Unlimited Rubicon Bruiser Conversions 6x6 LS3 Build

This 2012 Jeep Wrangler Unlimited Rubicon is a standout Bruiser Conversions 6x6 custom build with serious presence, power, and craftsmanship. Starting as a Rubicon hardtop, it was transformed into a full 6x6 conversion with upgraded drivetrain components, custom bodywork, premium lighting, and a highly capable off-road setup.

This gives the Jeep the strength and capability to match its aggressive 6x6 appearance.

The exterior has been heavily upgraded with GenRight Off Road fenders, a GenRight front bumper, full bed roll cage, custom Line-X exterior coating, black Line-X interior, metal badging, AMP Research side steps, and a custom removable tire carrier. It rides on 17-inch Hutchinson beadlock wheels with 40-inch Toyo Open Country M/T tires, giving it an unmistakable stance.

Inside, the Jeep features Katzkin leather seating with embroidery, Carolina Metal Masters grab handles, an Alpine Restyle audio system with JL speakers, amp, subwoofer, backup camera, and an 8-channel sPOD switch system.
