This kit is based around the Maxtrac 4" lift spindle and we combine the following parts to get 6.5" of front lift and 4" of rear lift for a level look (on 2008+ Titans we suggest only the 2" front spacer for 6" total lift and a level stance..please note in the comment box when ordering what year your Titan is or just call us). 
-Maxtrac 4" lift Titan spindles and Crown braided brake lines
-PRG 2.5" billet aluminum spacers w/ upgraded bumpstops
-4" rear offset-pin blocks
-9/16 grade 8 Ubolts
-Procomp carrier bearing drop bracket (older prg version shown in pic)
-PRG rear brake line bracket
-Bilstein 5125 extended-length rear shocks
Install should take about 4-6 hrs. Everything is 100% bolt-on except the carrier-bearing-drop-bracket as this requires 2 cuts be made in the crossmember with a sawz-all and 2 holes drilled. 
Note; parts from this kit may ship from a few different locations to fill the order. dont blow a gasket and call your CC company if you get one box a day or so before the others.
