I have a BDS question for you !
I have a 86 XJ ... I put a 2" shackle in the rear and 2" pucks up front ... that would have been fine , but the leafs on the Pass. side are sagging ... So and came across a BDS 3" lift http://www.bds-suspension.com/kits/430H "used" I plan on taking the shackle/puck lift out and installing the complte BDS lift ... my first question is .. will the BDS add-a-leaf take care of the sagging problem , or do I need to replace the main leaf first before I add the BDS leaf ???
