FSSR Front Spring Shackle Reversal, J10 J20 Wagoneer 1975-91; This is what you need to lift that Old FSJ and improve the ride at the same time! A front shackle reversal moves the shackle (spring pivot point) to the rear of the front spring where it should be. Allowing the spring to absorb the road impacts instead of transferring them to the vehicle. Chevy, Ford and Dodge set their front springs up this way and now you can also. These brackets are 100% bolt-in (no welding required) and the kit lifts the front 2 inches. Yes, after installing the kit and moving the shackle to the rear spring mount all the front alignment and caster are maintained! Maybe this is what you need to improve that rough ride and fit larger tires too--much better than a lift kit only! Our kit uses your existing springs (OEM or After Market) and will lift your vehicle 2"-2.5". The rear lift blocks are not included in this kit. We also have an optional front receiver hitch that provides a strong lifting/pulling point for your Jeep (instead of the aluminum bumper). The 2nd picture shows the optional front receiver with the original bumper/position.
