2020 SuperJeep Challenge Builder of the Year

Everett, WA (February 17, 2020) – Yukon Gear & Axle®, the leading performance drivetrain supplier, congratulates Rockstar Performance Garage owner Nic Ashby for being named the 2020 SuperJeep Challenge Builder of the Year.

Ashby’s win the 2020 American SuperJeep Invitational Championship was supported by a multitude of Yukon products. The vehicle features Yukon gears, axles, driveshafts, a Grizzly locker differential and a Yukon Zip Locker Differential. The inaugural event was held during the King of the Hammers offroad race in Johnson Valley, California. Ashby’s modified 1983 CJ7 Jeep Wrangler entry, “GRDLOC”, won unanimously by handling desert terrain and expertly rock climbing. The event was judged by an elite and diversified panel of industry experts – Courtney Hansen, Terry Madden and Greg Henderson.

The project took three years and was supported by many top-notch aftermarket sponsors who gave the on and off road vehicle its unique capabilities and style. GRDLOC featured a 4.4 supercharged Cadillac Northstar forged V8, Trophy Truck sized 3.0 King Shock Coilovers, Bullet Liner coated paint job, Scosche 12v Power Sport/Lifestyle Mounts, Throttle Down custom race frame, PRP racing seats, Mickey Thompson 46” tires, Genright Offroad Aluminum Armor, Billet K&N Filters intake, Forged wheels, 8 piston brakes from R1 Concepts, 9 speaker kicker audio sound system, Rugged Radios bluetooth internal comms, 7 independent coolers from Mishimoto and an ‘87 Dodge KingPin front axle/2001 11.5” AAM rear axle from Yukon.

The judges, along with Tony May, Executive Producer of the American SuperJeep Challenge, were quick to point out that Ashby’s GRDLOC stood out from the field for its marriage of form, function and creativity to earn the title. Ashby shared that this build has been his passion, which is a feeling that’s shared throughout his entire team. Rockstar Performance Garage is a collaboration between Rockstar Energy Drink and LDRSHIPdesigns, with the goal of creating a lifestyle garage.

“I am very thankful to everyone for developing this exciting invitational event to help showcase what can be accomplished with the Jeep Wrangler, and to Yukon Gear & Axle for their incredible technical support, and all of my sponsors who have been there believing in this project from start to finish,” he added.
Neal Hollingsworth, RANDYS Worldwide Director of Marketing says, “Nic is a visionary that is fearless in his approach to life and builds. We are very proud of his accomplishment as an entrepreneur and look forward to supporting him with more projects, which we suspect will be equally as interesting, award winning and fun. It was a privilege to be a part of the development of this incredible project with so many industry-leading brands, and we look forward to supporting him at more events throughout the year.”
