Kit Features:
- 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 springs 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.
- Bump Stop Spacers – Proper bump stop extensions are a must and our heavy duty kits stand up to hard use while keeping the tires off of the shiny new JT fenders!
- Johnny Joint Control Arms – Heavy duty adjustable upper 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.
- Johnny Joint Trac Bars – Heavy duty adjustable length Trac Bars included are our forged chromoly, organically shaped front bar and our chromoly rear bar. Our Trac 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.
