5.5 plus 1" BL sounds huge but it all relates to your tire size, honestly. I am SOA on stock XJ springs on all corners with a main leaf added to each pack. I think from STOCK I am a little over 5" of lift. But thats from STOCK height with STOCK wheels. Im running 37s and consider myself somewhat of a LCOG, considering the lift and tires.
Stock Height springs....all of the above Joe listed.
My next major major mod is purchasing new springs from Alcan, but at $220 each I have to wait a bit.
