If you are looking to get your Jeep JK ready for off-road adventures, then you need to be sure that you have the right suspension system in place. This Synergy Manufacturing Rear Suspension Stretch Kit w/ Bolt-On Lower Shock Mounts is the perfect way to do just that. This system works by lengthening the Jeep JK wheel base 8 inches. This improves both wheeling and climbing characteristics. You will still be able to retain your factory 5-link rear suspension design as well.
