Early adopters of the Mopar JL lift kit had been experiencing a front spring bowing issue (read about it here), to which Jeep promised a fix.
The fix has arrived. This redesigned spring perch (part number 68427380AA) has now been released to correct the spring bowing issue on the lift kits.
Owners of Mopar lift kits produced after May 1 need not worry about obtaining this new spring perch as those kits will already feature this new spring perch.
