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 are 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 Bar- Forged chromoly, organically shaped front trac bar combines a precise fit with incredible strength and rigidity that is only available via forging. The adjustability feature allows you to perfectly center the front and rear axles under the vehicle. High-articulation Johnny Joint ends provide maximum durability and suspension flex.
Optional Add-On Components - Add-on components enable the RockJock Sport Edition Suspension Lift to be customized for increased off-road capabilities and tuning.
  • Shock Packages - Select from a range of performance shocks with race-proven technology from Bilstein, Fox, and King to meet your requirements.
  • Antirock Sway Bars - The most popular off-road sway bar on the market enhances off-road driving capabilities with a 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.
  • Currectlync Steering System - For maximum strength, reliability, and confidence off-road, upgrade your steering!
  • Geometry Correction Brackets - Depending on your usage and application, check out our Geometry Correction Bracket sets and see if they are for you.
  • Axle Housing Johnny Joints - Adding this simple kit to your Sport Edition Suspension System converts 2 more pivoting points in your suspension to high-articulation Johnny Joint rod ends.
