RockJock's Sport Edition Johnny Joint Suspension System for JK Wranglers provides 4 inches of lift and allows for efficient clearance of up to 37 in. tall tires (larger tires will require aftermarket fenders and minor trimming)!

For those who intend to do more serious 4 wheeling and rock crawling, you'll want to look at all of the upgrade parts that RockJock has to offer that can be added to this kit to get your vehicle to it's full potential at any level of off-roading!

• 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 your JK’s 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. 
  
• Trac Bar Relocation Brackets - Restore front and rear suspension lateral geometry and produce better overall vehicle handling by raising the suspension roll center to bring it closer to the vehicle’s center of gravity.
• 37 in. tires – no inner fender modification necessary
• 38 in. or larger tires – aftermarket high-clearance fenders suggested/required
• 4.5 in. wheel backspace is recommended for all tire sizes

Notes:
** Actual lift heights may vary due to factory build specs and added equipment and accessories
