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.

💪 RockJock 4x4 rear control arms with Johnny Joints give your Jeep Gladiator the articulation and durability it needs when the trail gets rough.

That means more usable articulation, less resistance, and smoother suspension movement when the trail gets technical.

Put a Johnny Joint where it counts.

🪨🚘 Where are our RC’ers at?? We know you’re out there. And we know you get this.

Also, this reel is an actual event that happened. 😂 There was lots of 3am RC rock crawlin’ while out at GSMJI. It’s what happens when you’re hanging out with Big Dog.

Part 2 coming soon…

👀 There’s definitely a whole lot going on before you ever put tires on Hell’s Gate and we don’t hear enough about it. 😂

Anyone else think that drop in is wild? John even said he’s seen people get mixed up going down it.

☀️ Leave it to TSwift to remind us that August has slipped away into a moment in time. And that’ll probably be the last time we ever quote her. 😉

Fortunately, the tags and shared photos with us leave us remembering the past month fondly. And it looks like August was a pretty good month to the rigs out there.

Now we start that transition to fall, and hopefully the temps start coming down. 🥵 Regardless, we know none of that will stop any of y’all from getting out there and adventuring. Just remember to tag RockJock. We love coming along for the ride.
