Hello I have a 2006 f350 that I've had for several years now. When I bought the truck the guy gave me 3" coil spacers and rear lift blocks and a set of leaf springs. He had these installed prior to his selling. I have a new set of 35's coming and I'm considering putting the lift back on but I'm not sure if I have everything I need. So far I assume I'll have to get new extended shocks. Hoping someone can tell me if I have everything needed to do the lift.
Thanks for the info. Still trying to figure out what I have. Looks like the front coil spacers are 2-1/2" and my back blocks are total of 5" and that's without the add a leaf. Am I missing something here? I'm assuming that my blocks go as pictured.
The orientation of the coil spacer and the blocks looks correct. The factory F350 rear blocks are taller than the F250 blocks. If those blocks that are pictured are 5" I believe they are the oem F350 blocks that came on that truck from the factory. The F250 blocks are around 3" tall.
Are the blocks on the truck now shorter or taller than the ones pictured that are not installed? The combination of the 2-1/2" front coil spacer and the F350 blocks will achieve a very nice stance on your truck so like George above said, you'd only need longer shocks front and rear and new U-bolts for the rear.
If you currently have the shorter F250 blocks in the rear, only installing the front coil spacers will give you a "leveled" look where the front end is slightly higher than the rear. Some people like this look and some people do not. I personally can't stand it. So if you're like me and you don't want that look, you can either keep the shorter blocks and install the add-a-leaf, or remove the shorter blocks and install the taller ones with just the factory leafs.
On my previous '06 I had Bilstein 5100s with the 2-1/2" coil spacers in the front, and Bilstein 5100s with F350 blocks and factory leafs in the rear. I loved it, especially for the cost. On my new '16, I replicated that same setup and hated it. The ride quality is terrible, nothing like it was on my '06 and I don't have a clue as to why. I ended up ordering a full Carli system from George just this week. You might want to do the Fox 2.0 shocks as a small upgrade over the Bilsteins as most people agree they are a better shock. Whatever you do, order from George, he'll take care of you like he did me.
This is starting to make sense..doing a quick Google search of factory 350 blocks comes up with what looks to be what I have (pictured). As of now there are no blocks under the springs!..just the pedestal that's welded to the axle. The way my truck sits now I measure (from the fender) a half inch higher in the back than in front. Is it possible they removed the blocks to level the truck?

Soon as my truck gets home I'll post them.. So the stock stance on this truck would of been around 2 inches lower in the front?. I assume this is why the coil spacers are used to level the truck?
I really can't tell you what's going on here. Someone with more experience should chime in. It looks to me though that you have quite the hodgepodge of leafs going on back there. I would endeavor to identify what of all that is the factory leafs, get rid of the rest, install those 350 blocks you have, get new shocks, and call the rear end sorted. You already know what to do in the front.
for lifting usw a jack...much easier than trying to do it by hand :look:
ok but seriously soundsw like you should post up some pics of the rear set up like there was a block of some kind welded to the axle and the stock blocks on top of that at one point :dunno:
not a fan of stacked blocks but it is too common a practice to ignore the possibility.
of course this is all conjecture of a deluded mind without pictures

Those appear to be a spring-shop special. Even the F450/550 don't use an overload pack like that. It seems like the shop built up a set of leafs and removed the block to get a level stance.
From the original post, the low block is the spacer on top of the OEM leaf pack to separate the overload spring, as shown in the post before this one.
If it was my truck, I'd remove that spring pack (and get the dollars in scrap steel) and remove the forward spring hanger and reinstall ≈ 8" further forward and use longer leafs for 2008+ model.
Thanks for all the replies..here's a better shot of it. What I'm thinking is the top (4) set of springs was added and the bottom set are the factory springs. Probably going to remove the added pack and go back to the factory block then add the smaller block with the single spring on top. So the order from bottom would be factory block, factory springs, smaller block then the single spring (I believe it is an add-a-leaf).
I believe the springs that the previous owner had on top were the ones circled. Not really sure if they are technically called an "add a leaf". From what I gather they sit on top of the smaller block which is apparently called a REAR AUXILIARY OVERLOAD LEAF SPRING SPACER..
Well the factory block and this one. Which is smaller..less than an inch. From what I've gathered it's called the auxiliary overload leaf spring spacer. Every picture I've seen if one has it spring on top of the leaf spring pack with a single on top. So I guess that extra single spring is called an auxiliary overload leaf spring.
Well it appears this mystery had been solved. Searching the internet i couldn't find any spring pack like the one that I have on there now but that Hellwig looks like a winner. I bought the truck in 09'. The guy bought a big camper dropped the coil spacers and went back to factory tire size to pull. He ultimately sold it to buy a dually. I've had these parts lying around since then. So doing some rough calculations it looks like if I go back to my factory spring/block setup I'll gain around 3-1/2 to 4" of height. Then the coil spacers should level out the front. So I guess he actually lowered the rear end of the truck by taking out the blocks.
