3inch Rev tech to coil overs?

Hey guys, i've been searching around the site a bit but need some help.
I have a 3'' rev tech lift on my truck right now. Basically just spacers nothing fancy. Its kinda rough and i've been driving on it for two years. I run 285/75 R16's M/T's during the summer so that doesn't help too much. I was looking at putting some coil over shocks in the front.

The Toytech look nice and so do some of the others. My question is if i just toss on some coil overs on the front end will i have to do anything to the back? Can i leave the existing rev tech portion in the back? I know its kinda a dumb question but i'm not sure whether its better to buy the full kit around or not.

Any help and in put would be great. Also i was guessing that the coil overs would improve the ride, am i wrong?

 

sure, you can leave the revtek stuff back there (blocks i'm assuming) and just put on the coilovers but if your really looking to improve your ride i'd ditch the blocks and go with an add a leaf.

here's a great set up that will blow your mind. your truck will drive so much better than your current set up
