The pictures are of a rear, 3.5" square block some guys will upgrade to when doing the spring swap. Most others will use a 3.5" tapered block when doing the spring swap.

someone was asking about the blocks if they were 3.5 or 4 in.

I have pic's so I posted for measurement reference.

If you swap the spring packs front and rear from a diesel f350 to a diesel X (including the blocks from f350) will it sit as high as a 350, or is there a difference in the shackles/hangers also?
Can you use the overload springs if you get the brackets with rubber snubbers off the truck?
Can the rear truck sway bar be bolted to the X?

 

If F code springs are installed instead of the B codes, are 3.5" tapered blocks still needed for a lift in the back? Do you need longer u-bolts with the F code springs?

 

I've got a 2000 V-8 Ex with many miles. The springs are over due for replacement, and I want to go with F-250 springs and a sway bar to tame it a little. Would also like to maintain the 1" rake and avoid changing the overall height more than an inch.

Any suggestions for which springs to put on?

Thanks in advance!

Do you have a 4x4 or a 2-wheel drive?

If you have a 4x4, your limitation of not changing the overall height more than an inch precludes using F250 springs.

The popular V code, B code spring upgrade (using OEM F250 4x4 springs) along with a 3.5" tapered rear block will raise the height of your Ex approximately 1.75" to 2" overall, while still keeping the slight rake.

Stewart,

Thanks for the advice. The truck is a 4X4, but I guess an extra inch or so is a small price to pay for getting the heavier springs. BTW, your many posts on the subject have been very helpful. Just to confirm, V's up front, and B's for the rear with 3.5" tapered blocks (got the part numbers from one of your posts). Seems like I'll need different shocks too. Might as well add a sway bar while I'm at it. Any other problems/tips about the process?

Thanks again,

Steve

They aren't heavier springs, the rears are actually lighter. The stock "D springs" are heavy and flat, the F250-350 "B code springs" are arched more and have a large supporting bottom leaf which eliminates axle wrap and improves handling and ride.

Do the swap, you'll be happy like the rest of us.

 

Affirmative.

Whew, it's been quite some time since I've done the swap. I'm not sure if I can remember a whole lot, but I'll try.

You can do all this by yourself, but if possible, have a couple of buddy's come over to help because having extra hands is soooooo helpful.

The front bumper comes off by removing four bolts. After you remove it you can get to the front spring bolts. Removing the front bumper was really easy.

Having multiple floor jacks helps to remove the springs, as well as position the new springs easily.

When you do the rear springs, you'll find the rear A/C lines are in the way. They can be manipulated out of the way enough to get done what you need to do by loosening two of the brackets holding the lines. When it comes to doing this part, you'll see what I'm talking about. It's very intuitive.

Hopefully others who have recently done this job will chime in with any other tips they have.

While I was searching about how to upgrade my Excursions suspension I came across this thread. I love my truck but the suspension is lacking. I know its a bit old but the information was really helpful and I wanted to thank all of the posters for providing this in here. I think I am going to swap my springs out for some F250 springs. I also came across an article that compares spring capacities and measurements that may be helpful to someone else on the same quest as I am.

 

I put F250 springs on the front and Roadmaster Active Suspension on the rear of my PSD Ex.....it was absolutely perfect. Looked better, handled better, towed better. A great, fairly inexpensive upgrade
