I am currently running a 1.75" front spacer to compensate for bumper sag. When I install the 2.5" TF coil lift kit, I am assuming I will need a smaller like 1" spacer due to the stiffer/bigger springs. If that is the case, can I keep the 1.75" front spacer, and add a .5" rear spacer without any issues? That would end up giving me closer to a 3" lift.

Thanks

 

You can keep that front spacer, but that's a lot of additional height for the front. I think you will likely have a reverse rake with that much front spacer.

Remember, the 2.5" coil lift handles a heavy bumper and winch really well. It won't sag nearly as much as factory springs. My 2.5 coil lift settled less than 1/2" after I added lod midwidth and superwinch 9.0 with synthetic line.

 

After I installed a bumper/winch and swaybar skid I had a 1" sag. (measured at the front fender) I put on a 2.5 TF Coil w/TF shocks (4DR kit) and got 4" back from the from sag... Thus it gave me 3" more from the stock setup. I had planned to add 1" spacer in the front but couldn't use them without added items... longer brake lines.... etc.. I ended up returning the 1" spacers.

I got a solid 2.5" on the bottom skids... ~3 in front and 2.5" in back
