ok everyone i have a 2003 f150 fx4 im going to crank the tbars what size blocks does everyone use in the rear? did anyone need to extend brake lines?

if youre gonna crank the stock ones i doubt you could lift the front much higher than the back already is. i cranked aftermarket torsion keys then put 3.5" blocks in the back. could of done 4" blocks. i have some pictures on my profile.

I have aftermarket keys that lift the front 3" and 2" blocks in the rear

I did exactly what you did, with the exception that I went with 4 in blocks on the rear. I think 4 inch was a little much for mine though, probably shoulda went with 3 or 3.5 in blocks like you did. I had the 2 in ready lift keys installed in teh front on T-bars, and installed 4 in blocks with extended rough country shocks myself. Total was ~650 for all, including a lifetime alignment from Firestone. Was totally worth it to me

Also, if you lift the back up too high, you MAY get that little "thud" when you take off due to the angle of the drive shaft being changed. I put grease on the splines where my DS goes into the xfer case, problem solved.

only costed me 230 for mine counting the t-bar unloading tool. did all the work myself, got the keys off ebay for 50 bucks, and havent replaced the shocks yet though, i need to.

Damn, I shoulda done what you did. I paid a local 4 wheel drive store to do the work on the frnt, I did the work on the back supension. Oh well, I contributed to the local economy, I guess

Have you alredy bought one? Because I am actually trying to sell my keys/blocks because i'm upsizing to a full suspension lift. They are in great condition. I already have a couple people interested but pm me if youre interested.

i was thinking about the aftermarket keys i just dont know if i like the idea of putting that much pressure on the front end

at the beginning i had to replace my cv shafts and ball joints, but those were pretty much worn out anyway. i doubt ill have to replace anything again any time soon.
