Ford Excursion :: Rear Springs Versus Blocks?
Jun 24, 2010
I'm going to be installing a 4" lift on my truck and was wondering what the pros and cons are using springs or blocks. I have the option of going with either the pro comp 22210/22415 springs or 22210 with a 5" block. With the block I'd be saving around $200 but I guess my main concern is ride quality. Dont know if the stock rear springs have issues like the front do. I'm probably going to go all spring but it would be nice to save a few bucks.

Finally pulling the trigger on some springs so I can get this work done, Tousely prices were great on the W's compared to local dealers. Here are some questions.
1. I am planning to go with the W springs up front.
2. Can I still use the B for the rear mod, or do I need C's to keep it level? (Or F's)
3. Do I need blocks in the rear, or just the springs on the axle?
4. Do I need the 2" shackle up front?
5. I have dual Fox shocks that came with the ex when I bought it. The prior owner said they ran a little rough. Are they able to be re-valved, or is it cheaper to go with Bilstein?

Here's a pic of rear springs off a 4X2 Ex.
They look the same to me with the exception of not having the bottom overload spring with the rubber snubber on it for the axle wrap.
I need a pair of stock rear springs so I can pull the bottom two leaves off in order to do a modded B-code, and these are available for me to use if they will work.

My Ex has a ProComp 6" lift that was installed in 2004 (it's an 03) and it seems that the rear springs are worn out and sagging. I'm assuming the lift used the stock springs and blocks. I haven't measured but I'd say the rear is 1" - 2"s lower in the back. Question is should I replace the springs with stock ones? Maybe get springs that'll give me some lift and remove the blocks? Airbag it?

Since I bought this '05 Ex, I have had a driveline vibration. Not bad mind you... just barely noticeable when I let off the gas going 50+ mph. I had my local Ford dealer change the Ujoints and it worked a little.
I just installed Firestone Air Bags on the rear axle. I put 20 lbs. of pressure in them and it raised the rear exactly 1 inch (I measured before and after). After the air bags were in and pressurized and the rear lifted 1 inch, I took it for a drive. WOW! The driveline vibration is completely gone. Smooth as glass.
Question that I need opinions on from those who have more experience with an Ex than I do: Did my rear springs sag enough to cause a driveline vibration? And did the lifting of 1 inch put it BACK to stock height so that the driveline is now correct?

Who has installed 3" blocks in the rear. I've been working out of town for a few months and have scraped up a little extra money. With that said, I would like to add a leveling kit and rear blocks to my truck when I get home. I'm aware that adding blocks will increase axle wrap when accelerating hard, but I rarely tow and really don't beat on my truck that often.

I've done a ton of searches and everyone talks about the 250 rear blocks being 2 inches. I got under my truck the other night and my factory blocks measured to just shy of 4 inches. It seems like everyone says that those blocks only come with the 350s...
is there some sort of package that I might have to come factory with the larger rear blocks?

I have a quick question, but thinking of changing out my stock OEM rear axle blocks for the 2012 F350 SD 4x4 SRW type.
Does it matter what the wheelbase is?? Model being a CC, SC, etc?
Or...are all 2012 F350 SRW rear axle blocks the same?

I want to know if there are any issues when removing the rear block, also do I have to put a new block in or can I just leave it out ....

I have a 2014 F350 (specs in my signature) and I want to change the 4" rear blocks out for F250 2" blocks to lower the rear of the truck.
Looks like a fairly straight forward replacement but I have a few questions.
Will the shocks need to be replaced? I do eventuality want to replace them as the stock ones are not that great but I only have 2500 miles on them.
When I do order new shocks for my truck after the changing the blocks do I order shocks for a F250?
I would like to go OEM parts for this but I am having trouble finding the blocks and u-bolts that I need. What are the part numbers for these?
Anything else I should know about to do this swap?

Been chasing this for a few weeks and getting fed up. Have a bad metal on metal "creaking" noise from the front at low speeds.
Background - Replaced springs with X code front and modded C code rear from Junior at ATS. Also replaced shocks at the same time. All hardware tightened with weight on suspension. Have rechecked torque on ubolts many times, even loosened and retightened both ends of the shackles, sway bar links, shocks, etc.
Can't get the noise to go away. Hard to pinpoint exactly where it's coming from but you can "feel" the noise in the back half of the front springs.

Trying to figure out if my front leafs are factory or not. I assume so but they look extremely weak for a 9k rig.

I recently purchased a 2000 Ex Limited 2wd. It is stone stock except a slight lift. This lift gives it a pretty significant rake that I'm not a fan of. I'd like to get this thing leveled out without spending a fortune and I believe that would require the knowledge of the FTE.
The pictures below show the rake and existing suspension mods. With 285/75 16 Tires there is about 6" clearance from tire to fender on the front and 9.5" in the rear. It has a 2" spacer under what I imagine is the stock front coil spring and a 4" block below what do not appear to be stock leaf springs (guessing because the anti wrap spring is not present).
I'd like to get the front end to sit about 3" higher than it currently is to better match the rear. Lifts of any type are foreign to me. What front springs (and other components) do I need (and what brands would you recommend based on hard earned experience) to make this thing work?

Have been the owner of a 96 4.0 AWD for 10 yrs and if they still made this van I would get one in a heartbeat. Been doing a search on how to replace the rear coil springs with no luck... is there special tools or procedures involved?

I have a 99 SD 250 diesel, I also have a broken rear leaf spring. My truck has a 3 1/2 in. block between axle and leaf. My question is this. Can I remove the block and install 4" lift leaf springs without messing up my pinion angle? The blocks look square. But someone toldme once they are made to a specific angle for rotating pinion for better u joint alignment. Sounds like it could be true.

I would like to add rear overload leaves to my 2016 F250 that for some reason I didn't order with the camper prep package. From what my internet research tells me I will need to add the frame tabs and rubber bumpers, the overload leaves themselves, and of course longer U bolts.
My question is, in all of the pictures I can find, there in an intermediate spacer block between the regular leaf pack and the overload leaf. I can find a part number for this block ( 2C3Z-5594-AA ) only for 2002-2007 trucks. The parts diagrams I've seen online at various Ford sites don't list a part number for this block on current model trucks. Most just give a single part number for the whole leaf pack.
For 2014-2016 F250 with the camper package, or an F350 know what part numbers I might be looking for? Do the newer model year trucks still use an intermediate spacer block? Any chance someone with one of the aforementioned vehicles can post a picture of what the overload leaf setup looks like on a new(er) truck?
I would assume if you snap an overload leaf you can get a replacement from Ford, so why can't I find a part number for them either? I'm pretty sure I will have overloads built at a local spring shop anyway, but at least want to make sure I'm matching the correct and current factory setup.
