Product Description
Synergy Stage 4 Long Arm Suspension | 4-4.5" Lift | 4 Door (Wrangler JK 2007-2018)
The Stage 4 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% bolt on system with no welding required. This system will fit 37" tires with stock fenders or 40" tires with high fenders.

Notes:
** 2012+ JK's lifted over 2" will require exhaust spacers (5017), or a front aftermarket drive shaft to prevent interference with the exhaust.
*** 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
**** 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
