On most 4" lifts you will want to lower the cross member. It all comes down to driveline angles really.

My 4" RC lift came with a TC drop. I took it out when I installed an SYE and CV driveshaft.

By a piece of 1x1x3/16" 6 feet long and cut it to length. Drill holes, buy longer bolts and you're done.

Also check to see if the RC kit had a drop pitman arm, longer sway bar links (or drop brackets), and longer brake lines. These Items are usually not in a budget priced kit.

The answer to the original question drive it after the lift and see if you have drive line issues. And yes you can use fender washers and longer bolts if you need to.

Look into what Jeepmaster said. Lots of times you will end up spending more money on one of those budget kits in order to get the other stuff you need. In the long run, buying a nicer lift kit for a little more gets you all the stuff you need in one package and gives you a better ride with better quality springs that aren't going to sag down to a 2.5" lift after a year. Save yourself some headaches too and go with a double cardan/CV style rear driveshaft after the lift and leave out the TC drop. Price out Tom Woods or Tatton's shafts, they are about the same. It will save you a lot of U joint woes.

Of course if you have a Q trac, your driveline angles may no be a problem. Perhaps you could fill in your profile.....

They are double-cardan driveshafts. People that don't know the difference between a double-cardan joint and a constant velocity joint call them CV's (mistakenly). Unfortunately, a lot of vendors also call them this, perpetuating the problem. Same deal with people and gear vendors calling high pinion gearsets "reverse rotation". They don't rotate in reverse. The gears are reverse cut, meaning the spiral goes in the opposite direction. The gears still rotate in the same direction as standard-cut (low pinion) gears.

This is how NAXJA Midwest Chapter elected officials like to treat their resident users and former multi-year supporters.
