RockJock Pro Edition Features

Antirock® Sway Bars - The most popular off-road sway bar, enhances off-road driving capabilities with balanced performance of front and rear suspension in rugged off-road conditions. Off-road traction is improved with increased suspension flex and by equalizing and distributing the weight of the vehicle over all four tires - without the overly loose feeling created by sway bar disconnects

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 larger 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

Johnny Joint® Control Arms – Heavy-duty upper and lower control arms feature RockJock Johnny Joints, the original and most durable high-articulation urethane suspension joint on the market. Johnny Joints 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 they are used by multiple commercial suspension companies, for both street and off-road suspension systems Learn More Here

Johnny Joint Trac Bars - Heavy-duty adjustable length chromoly track bars combine a precise fit with increased strength, and adjustable length to perfectly center front and rear axles under the vehicle. High-articulation Johnny Joint ends provide maximum durability and suspension flex
