RockJock Sport Edition Features
Johnny Joint Lower Control Arms – Johnny Joints, the original and most durable high-articulation urethane suspension joint on the market. They feature a smooth steel ball that pivots inside a proprietary urethane shell to provide over 30 degrees (per joint) of quiet, shock dampening articulation - without the excessive deflection found in soft rubber-based “flex joints.” Johnny Joints are so trusted, that multiple commercial suspension companies use them, for both street, and off-road suspension systems Learn More Here
RockJock-Spec Dual-Rate Springs - Feature a soft initial rate that absorbs small bumps and trail chop, to deliver a smooth, comfortable ride, while a firmer secondary rate helps soak up harder impacts and reduce bottoming. A key differentiator of RockJock-Spec dual-rate spring is the positioning of the crossover point between the initial and secondary spring rates so that a portion of the softer initial rate is available and active at ride height before crossing over to the firmer secondary rate deeper into the travel
Upgrade Options – The individual components included in the Sport Edition are the same as the components used in our full Pro Edition Suspension Lift. So, when it’s time to go to the next level and take on more extreme terrain, upgrading the Sport Edition to Pro Edition, is as simple as selecting the desired add-on components – with no need to replace parts that you’ve already purchased and installed
