Obviously I'm not the good Doctor Hunter but yes, those measurements were from the ground to the wheel well.
This thread is a great resource for anyone looking to modify their EX suspension, it shows many different setups and the various amounts of lift attained from each. Good stuff!

Hmmm, not according to the portion of the quote in quotation marks I highlighted.

Oh, I know what it says Bossman, but if you read the entire statement from the original post it become obvious that he was measuring from the ground (and just stated the measurement points incorrectly) plus looking at the pics the distance from hub center to wheel well isn't several (8" to 9") inches taller than the tires (they are 34" tall).

"Anyhow, below are my pre and post pictures. With the X-codes on the front I picked up 2.5 inches of lift. I picked up nearly the same on the rear. Now, with my 275/65/20 tires on and the updated springs, my front sits 42.25 inches to the wheel well measured from the center of the hub. The rear sits 43 inches."

Wait, what? We have expectations of reading posts and not scanning posts? Reading, so specific information that is present within, will easily provide the information to those of us familiar with the Ex suspension? The heck you say!

Hunter, your X looks great. I was looking for some good pics of X codes in the front. I am getting ready to do some X/C codes on mine. I did the swaybar first and can't wait to do the leafs.
Good Job and thanks for the tips

After reading and re-reading the forums, I decided that X-codes and modified B codes would suit my interests best. Located the springs I needed and proceeded.

Started at 7:00 this morning. Got finished exactly 4 hours later. Spent several hours this past week on the phone rounding up parts, stopped by the salvage yard to pick up the springs. Also went by the local spring shop and had them custom make some new U-bolts for me. I also got some new center bolts for the modified rear spring packs. Finally I ordered some new bushings from Energy Suspension to place since I was under there. As it turned out, they sent me the wrong size bushings. However, my OEM ones weren't in bad shape anyhow. I think they have a year or two left in them.

Anyhow, below are my pre and post pictures. With the X-codes on the front I picked up 2.5 inches of lift. I picked up nearly the same on the rear. Now, with my 275/65/20 tires on and the updated springs, my front sits 42.25 inches to the wheel well measured from the center of the hub. The rear sits 43 inches.

Before:


After:

Technique:

I have a buddy with a shop and a lift which made life much easier. We put it up on the lift and worked on one axle at a time. On the passenger rear side the only complication we ran in to was having to unbolt and move the rear A/C line in order to get the front spring bolt out. Otherwise the rear was very straight forward.

The fronts were a little more difficult just because we had to remove that low hanging Prius saver from under the front bumper. This had to come off in order to get the front bolts off. Also, on the driver side we had to take the entire shackle off of the frame instead of removing the spring from the shackle. The front drive shaft was in the way and we couldn't get the bolt off to remove only the spring. The front and rear custom U-bolts worked fabulously.

Tips:

1) I would not have wanted to try to tackle this job without air tools.
2) Make sure you have a torch handy as many of my bolts had loc-tite on them and were impossible to get off without torching them. My truck has never seen snow or salt so corrosion was not an issue. If your truck has rusty bolts this will complicate the process more.
3) IMO you cannot safely and efficiently do this by yourself. You really need another person, especially to remove the old spring and to seat the new one in place.
4) I suppose you could do this with a few jacks and jack stands, but having the lift and TALL jack stands was a God send.
5) Instead of buying new springs, look for some low mileage ones at a salvage yard. Also, don't buy U-bolts from the dealer. Dealer cost PER U BOLT was $27. I got custom make ones with higher quality steel from a spring shop for $14 per bolt. My springs were also $50 each from the salvage yard. In total I have less than $500 in this whole process, and $100 of that was for my buddy for his time.

Driving Impression

I am extremely satisfied with this swap. My truck has never ridden so good. On the highway any steering wander is absolutely gone. I tracks straight and true. Expansion joints are no longer a problem. My truck rides firmer perhaps, but better and much more comfortable. Firmer makes one think of harsher, which is absolutely not true. Firmer means you aren't bouncing all over the road. The body of the truck isn't sloshing around like a water bed anymore. I even took a back road home this evening which is really rough, and I was smiling ear to ear going down this road I used to avoid. Now it rides like a very nice riding truck. Sharp curves are more confidently handled. Lane changes are quick and crisp. The X codes gave me enough lift to clear my 34.5" tires. They have some miles on them already so I don't expect them to settle much more.

Final Impression

IMO I am very pleased with the X codes. If I would have gone with new V codes they probably would have been OK for the first while until they settled, then I would have a little too much rake for my liking. With broken in X codes it should sit right where it is for a long time. The ride is absolutely perfect, as is the height with the modified B code swap. With 1" or trailer induced squat I will be nearly level. This combo of springs seems like it was designed for this beast of a vehicle. Best mod I have done to date, which is saying alot. I have now done:

1) 2008 tow mirrors
2) 2007 OEM wheels
3) 275-65-20 michelins
4) Third row headrests
5) A smattering of 6.0 PSD upgrades.

I highly recommend this mod to anybody, whether you are experiencing steering wander or not. I really can't say enough about the new driving experience

Reviving this thread as this is my favorite pic of an XB Swap to date, what size rear blocks was this using?

I did the X/modB swap on mine as well, here are some pics. Thinking of swapping the factory 2 blocks for some 3.5 f250 blocks now. I like the ride a lot, and the look, but the rear does look to sit just a tad lower than the front on level ground.

When I did my X/ModB swap, I used 4 inches of blocks and it sits level loaded.
X-codes are the way to go if you have a plow on the front.
