Leaf Springs Installed

Long-Travel Boomerang shackles are longer and provide 1.5-inches of lift while also giving the leaf spring more ability up and down for more travel. Deaver prerunner leaf springs were used in conjunction with the Synergy 4-Link Long Travel Kit. This kit still uses stock-length (eye-to-eye) leaf springs, so you can still buy off-the-shelf springs that are readily available. We matched the rear to the front with another pair of Fox Performance Series 2.0 IFP Shocks. The Synergy wheel adapters are not necessary for this kit and were only used to put factory JK take-off wheels and tires on our XJ to save some money.
