The Synergy Manufacturing Stage 4 Suspension System is the perfect suspension system if you want to get the maximum in off-road performance and capacity but you do not want to sacrifice the quality of your ride at the same time. This Stage 4 System has all of the high quality components that you have come to expect from the Stage 3 System and adds in important improvements. Stage 4 systems have adjustable long arms as well as long arm mounting brackets. No welding is needed when you install this bolt-on system and it is designed to fit 37 inch tires if you have stock fenders and 40 inch tires if you have higher aftermarket fenders.
Requires a maximum 4-3/4" backspace wheel or wheel spacer with factory wheel setup. 4-1/2" back spacing is recommended.
2012+ JK's lifted over 2" will require exhaust spacers (5017), or a front aftermarket drive shaft to prevent interference with the exhaust.
