Hey guys, new to the forum! Finally bought an Excursion!

The previous owner says he put a 4” lift in (had the rear custom done by BDS so as to not use blocks). I am curious how tall the fender/quarters are on a stock (non sagging) excursion? I would also be curious to know how high the top of the rear bumper sits on a stock height truck. Considering removing the lift. Thanks guys!

 

Welcome to the EX forum!

The best way to measure the suspension is to go from the center of the wheel hub up to the fender lip, that method removes any variations from tires and inflation. Stock 4X4 is (I think 23") front and 24" rear. We have thread that discusses both the stock ride height (where you can double check my rusty memeory) and a wide array of modified setups and the resulting measurements, its along thread with plenty of info in it. https://www.ford-trucks.com/forums/1...easurents.html

Which motor does it have and with the lift and I'm assuming taller tires has the gear ratio been changed? Just something to consider if going back to stock-ish rubber. I swapped my stock 3.73s for 4.88s and ran the same 32" tires (stock is 31.6") for two years, enjoyed to great hot rod like performance but the mileage suffered a bit.

 

Thanks for the reply! Looks like your memory isn't that bad! Haha. My truck has the 7.3, 35" tires, gears have not been changed to my knowledge. My measurements are:

DF - 28"
PF - 29"
DR - 30
PR - 30.5"

From that thread you sent me: "So, with my 4" all spring BDS lift, I am getting 27" in the front and 28" in the rear." Maybe the lift that was installed is actually a 6"? Either way it is too tall, before I spend some time searching do you happen to know off hand how much lift is required to keep my 35's?

Thanks again!

 

For bigger tires the front is the challenge. On mine I run 35.28" Nitto Duras and my modded X code springs give it exactly 3 7/8" of lift over stock. Those 12.8" wide tires are mounted on a set of the '04 Lariat 18" wheels, so they are sitting in the OEM location under the big wagon and the only contact is on the spring but only full steering lock. With wheels of the OEM geometry I think that 35"s could fit on a stock spring with a wee bit of trimming.

 

Thanks again! Is their a thread that explains the different springs? (codes/modded)

 

Yeah, bunches of them around here actually, I'll try to dig up one with the chart that shows what each spring will add to a stock EX. In the past using the various pickup springs was the go-to for lifting our EXs, more recently and with lots of help from Pirate (big time champion off-road racer with tons of suspension knowledge) the new favored setup is with the Pro Comp all spring 4" lift.

 

Here's a copy of an earlier post I made in another thread talking about the various pickup truck springs when used on an EX, hopefully this helps to explain what the spring letter identifiers refer to.

The Ford spring lettering can be a little confusing compounded by the fact the aftermarket sometimes uses those same letters but with differing spring rates and travel amounts. I copied the info in this chart over time here from a few members posts discussing the front truck leaf springs and how they affect the ride height of the gas and diesel EXs. I don't have the same info on the rear springs unfortunately.
Clipped from a past post:
This is my Spring cheat sheet complied from various posts here on FTE mostly from old posts by bruce1954 and Monsta.

The following only applies to 4X4 EXs, the 2X4 rigs have coil springs up front. All EXs came from Ford with G code rear springs, the V-8 EXs all came with B (front B code is much different than rear B code, confused yet?) 4100lb, all V-10 EXs came with C code fronts at 4300lb and all PSD EXs had D codes at 4700lbs.
All the other codes discussed come from SuperDuty trucks (they came with springs that don't suck from Ford.)
Spring........Capacity.....Rate lbs/".....Max travel.....V-10 change.....PSD change
B (V-8)......4100lbs.......330 lb/".........5.02"...........-0.25".............-0.66"
C (V-10)....4300lbs.......350 lb/".........5.01".............0.00"............-0.37"
D (PSD).....4700lbs.......380 lb/".........5.14"...........+0.33".............0 .00"
S codes.....4000lbs.......370 lb/".........4.34"...........+1.22"............+0 .88"
T codes.....4400lbs.......390 lb/".........4.63"...........+1.42"............+1 .11"
U codes.....4800lbs.......410 lb/".........4.89"...........+1.60"............+1 .32"
V codes.....5200lbs.......430 lb/".........5.13"...........+1.77'............+1 .50"
W codes....5600lbs.......450 lb/".........5.34"...........+2.77'............+2 .52"
X codes.....6000lbs.......470 lb/".........5.54"...........+2.90"...........+2. 68"
W codes are from F-450s and X codes are from F-550s and other SD trucks with snow plow prep.

The above spring info has been gathered from posts here on FTE by "monsta" and "bruce1954".

Hopefully this will help to answer some of your questions about the "lettered" springs. The ONLY way to verify what springs are on a pickup is if the original door info sticker is still on the truck, under the SPRING header will be the truck's OEM spring codes front then rear such as "V V B B" where it has V code fronts and B code rears. Look at your EX door sticker and it should read C C G G if its a gasser or D D G G if its a PSD.

Another very good option is the ProComp 4" lift springs, Member Pirate is a very sharp suspension guy and he has laid out the list of all the parts needed to redo the EX suspension with those aftermarket springs. If I was starting over from scratch I would most likely go with the ProComp springs and air bags for my tow rig EX.
