RockJock 4x4 by John Currie on Instagram: "⛽️ The age old wisdom: when in doubt, thottle out. — Our good buddy Marvin aka @jeepstermcjeepface from Flex, Rocks & Rollovers knows just how to do it. Get them tires all warmed up and then slam the skinny pedal. — His custom built Jeepster is an amazing build with some solid quality parts on there, including our rear Antirock and Johnny Joints throughout. Perfect for these off-roading conditions. #rockjock4x4 #antirock #wedontjustmakethisstuffweliveit
