No. Want to hold on to them. Sorry. But I'm sure there is someone out there that will part with theirs.

I'm probably going to start another thread because this got me curious. My stock height in the rear is 39.25" and 36.75" in the front on a 2018 Lariat 4x4. I don't really understand why the trucks with the same specs vary so much in terms ride height. I'm going to get an Auto Spring 2.5" leveling kit to level the truck which should make the truck exactly level. However, I would prefer my rear height to be at least 40" so I may put a 2" block in to slightly raise the back which would give me a rake of around .75" which should be fine.

Could be other factors such as bed length, crew cab, super crew cab, towing pkg, etc.

It adjusts the whole truck backwards as well as downwards because of the redistribution of the body weight. No different then dropping the front a tiny bit when tapping the brake.

FML lol nothing ever goes smoothly. Tried this last night and everything was going perfectly, bolts came off easy, block came out no prob and sure enough i go to lower her and the leaf springs centering holes are off and wont fit in the hole on the axle. I used the leaf spring jack method so there was no room for me to wiggle it in place. I did get a bit lucky though because the block went back in no problem and the holes lined right up. I was beyond terrified because my truck was half way in the garage and it was 9 at night. Buying some jack stands today and hoping to get her done tonight

After some research it appears that the problem with reusing the u-bolts has to do with the threads "rolling" when torqued and therefor doesn't hold the correct torque when reused. But in this situation with removing the blocks, you now are using virgin threads as the nuts are traveling further up the bolt then before so you are torquing virgin threads. Does this make sense?

Makes perfect sense. That's what I did with mine. Still nose down though

I just removed my rear spring blocks 2 days ago on my new '18 Lariat and the truck looks great now, just as if I'd used a leveling kit. Very simple job and only took and hour start to finish. I no longer tow anything and seldom carry anything too heavy so this method will work well for me.

Top of the rear fender well is 1" higher than the front fender well.
