I just installed a rough country 4.5" kit in my 99 XJ. I have to say I am extremely pleased with the kit. but more noticeably the new design of the LCA's. the last RC kit I installed the LCA'a had vulcanized bushings that were an odd ball size. once they wore out there was no option for replacement without replacing the lowers. the new style lowers have pressed in bushings that appear to be the same size as OEM. this is a huge plus over the previous design. I thought I'd share this, there is a lot of negative talk about RC bushings. it appears they have corrected this problem and I though the community should know!

 

Just installed these as well, the Clevites look beefy!
