J10 J20 Wagoneer Shackle Reversal FSSR [front spring shackle reversal] rear lift kit 2.5"(over 200 Sold) This will not fit vehicles with Post Mount springs 1965-'73 trucks

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.  Doing so Allows 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 included in this
kit note: the replacement U-bolts are 5/8" in OD.  Which requires that the plates be enlarged to 5/8-3/4"..  We also have an optional front receiver

hitch that provides a strong lifting/pulling point for your Jeep (instead of
the aluminum bumper).  Note:  If you are using springs with 4+ inches of lift, you may need the One Ton offset steering Drag Link for steering clearance-listed on this site.  The extreme arch of the spring moves the axle forward.
