JK 6.0 Inch Lift Stage 4 Suspension System 07-18 Wrangler JKU 4 DR

Synergy Jeep JK 6.0 Inch Lift Stage 4 Long Arm Suspension System is for those wanting maximum performance and capability without sacrificing ride quality. It carries over the quality components of the Stage 3 System, but improves upon them by swapping out the Standard Length Control Arms for Adjustable Long Arms and Long Arm Mounting Brackets. This is a 100 percent bolt on system with no welding required. This system will fit 37 inch tires with stock fenders or 40 inch tires with high fenders.

Fits:

07-18 JKU (4-Door Only)

Details:

• Stage 4 key features are front and rear track bar relocation brackets, flipped drag link, and all adjustable upper & lower long arms


• Front and rear bump stop extension kits


• Front sway bar links (Currie Anti-Rock required for the rear, see notes)


• Front and rear extended stainless steel braided brake lines


• Front and rear brake line relocation kits


• Synergy double adjuster sleeve and pinch bolt assembly allows for adjustment of control arm, track bar, tie rod, and drag link length without removal


• Front and rear track bar relocation brackets raise track bar mounting positions increasing suspension roll center heights which improves handling on and off road


• Lower control arms are manufactured from high quality crush resistant 2 inch X .250 inch Wall 1026 DOM tubing


• Features Synergy Dual Durometer Bushings (DDB) with Teflon bearing surface for a maintenance free design focusing on performance, flex, longevity, and ride quality.


• Front and rear lower shock mounts


• Optional front sway bar disconnect system for ultimate trail articulation mounts sway bar up and out of the way when disconnected from the axle


• Progressive wound coil spring manufactured using the latest in CNC hot winding technology keeps spring from coming unbound at full suspension droop


• Suspension components feature an abrasion-resistant powder coat finish for maximum durability and corrosion resistance


• 100 percent bolt on components assure an easy, trouble free installation with the use of basic hand tools


• Requires a maximum 4-3/4 inch backspace wheel or wheel spacer with factory wheel setup. 4-1/2 inch back spacing is recommended


• Synergy suspension systems are a modular design so all components are available separately


• Available For Right Hand Drive (RHD) Vehicles

Notes:

• Diesel models will require a set of spacers to be fabricated for installation. The transmission cross member is located further back on diesel models and the front long arm brackets will not sit flush to the cross member


• Use Currie anti-rock rear sway bar kit with CE-9901RD2 14 inch end link rods if wanting to run a rear sway bar


• Trimming of skid plate for clearance to front driveshaft will be required with stock driveshaft - aftermarket driveshafts highly recommended


• Relocation of parking brake cables will be required, move from over cross member to under cross member


• Additional bump stop spacing may be required for larger tires if air bump kits are not used


• Springs retain the factory rake of the vehicle where the rear is higher than the front. Vehicle should sit level when loaded. Request one size shorter rear springs to level the vehicle out when unloaded (Recommended rear shocks will be too long with 4.5 inch rear springs. We recommend limit straps, coil retainers, or shorter shocks be used.)
