Currently my TJ has a 2" spacer lift at the top of the coils. I'm looking at taking that off and putting a 4" lift with new shocks, coils, sway disconnects, control arms, etc.. I'm trying to determine if the bump stops in there now are part of the 2" spacer lift. or if I can take the 2" spacer out and the bump stops will remain. I wasn't sure if it was normally one piece or if they were separate. Thanks.
