I have my 3" Revtek spacer kit for sale. In perfect condition, it has only been on the truck for 30,000 miles. Comes with 1.25" rear block option and extended U-bolts. Kit includes everything pictured. (Not included in the kit: extended studs for front coil assembly). Will also come with instructions for install. Great kit for fitting bigger tires and giving the truck a nice stance. I live in Scottsdale Arizona, 85259. Will ship on your dime. Paid just under $300 for the kit brand new, so I will sell this for $125.
I spoke with Randy at Revtek, he confirmed that this kit will fit all years from 2005-2011 with no problems. He recommend using the diff. drop kit, which you can buy separately, but did not confirm whether or not it was necessary. (if anybody can chime in and verify this it would be appreciated). The part number for the diff. drop kit is: RTDD2-KB.
As for the studs, Randy at Revtek says you have a few options; 1. You can use the factory studs and nuts for assembly, but just turn over the nuts to get full thread engagement. 2. You can buy new studs from Revtek. 3. You can buy new nuts from a hardware store, he said to use a 10mm flat nut.[/QUOTE]
