JR spring (jcwhitney of chicago). EDIT A (very likely) cheaper alt would be to dissassemble em & have a local spring shop rearch the main leaf(s) then you reassemble. Measure the bumper height to ground right now then jack it up till you get the height you want then measure the difference & give that number to the shop. MORE EDIT If you do order tailor made ones get em with 1" more arch (height) than stock
