RockJock 4x4 by John Currie

RockJock 4x4 by John Currie Proven professional off road products and accessories since 1985. RockJock continues to progress and innovate as new platforms of vehicles are introduced.

RockJock by John Currie’s roots run deep as jeeping has been a love of the Currie family for decades. In his off-roading adventures, John pushed the limits of his vehicles coming to the realization of the shortcomings of the equipment. Thus, it became John’s goal to design and build the best-performing, strongest, most durable products on the market. A Jeep suspension upgrade product line was firs

t developed in the 1980s based around Jeep CJ and YJ vehicles. Fast forward to 1998 and John’s off-roading passion evolved into professional rock crawling competitions. In 2001, John Currie took home the 1st place trophy in the Extreme Rock Crawling Championship Series, in a RockJock equipped Jeep TJ Wrangler. This was the first of many victories and championships for John, and the victories have continued with various other drivers of RockJock equipped vehicles in numerous rock crawling, Ultra 4 and desert racing categories! From the JK Wrangler, the JL Wrangler, the JT Gladiator as well as the all-new Bronco, John Currie personally continues to design, build, test and sell the finest, cutting-edge, high-end suspension, steering and towing components available.

🏔️ From technical rock gardens to steep ledges, RockJock 4x4 steering and suspension components are engineered to keep you moving when the trail points up.

And this climb on Death Row was pointing way up.

10/10 would climb again.

🐐 It’s time for another throwback to John Currie out doing what he does best.

Years and years of competing, testing, refining and developing is at the heart of RockJock. It’s what John has been doing since the 90’s and what he continues to bring to RockJock today.

Who remembers this obstacle?

🇺🇸 What can’t Captain America do!?! 🦅

Unless you’ve been living under a rock for the past week you would know ⚽️ is here in America. And, we at Rock Jock are pretty big fans around here, so today is a big day to say the least.

So whether you’re out on a trail, heading to one, or “working”- plan a little break this afternoon to show some support to the boys in Red, White & Blue!
