And a RWD non-ER battery?The Rally springs will lift a GT about 1-3/8” settled. A non-GT ER battery AWD car will be lifted about an inch once settled.
The front will lift from 3/8" to 1/2" more due to the missing front motor and associated drive gear. Rear spacers may be needed to level the car out. Alternatively, the front springs could be shortened to the correct static height. The LFP battery weighs close to as much as the NMC battery in the ER cars, so the extra height gained from that will be negligible.
Steve above ^^^ is correct but I have seen several variations. The Premiums I have installed the Rally springs on have had a height increase from 3/4" to 1 1/4" depending on if they are AWD and have the EX battery or not. The GT's have been 1 1/4" to 1 1/2". Not sure why there have been variables on the GT since they are all AWD with EX batteries.
My Ext AWD went up 3/4 inch after adding rally springs. Visibly it is not obvious to me, but the first week just sitting in it while driving, I definitely felt a difference, but now it’s just feels “normal”
Similar for me. The car definitely looked surprised when we first installed them, and for awhile I noticed the height difference when getting into the car, but now it merely feels
I've got about a 1/2" rakeSteve above ^^^ is correct but I have seen several variations.

Yesterday installed Rally springs on a Premium (AWD, STD battery) and it raised it to 30 1/2" front, 31" rear. I cannot say what it was stock because the springs I took off were Eibach lowering springs from when we installed them a year ago. Maybe you can check out what your car is compared to this one?
Again, for your car I would say between 3/4" - 1 1/4" depending on how it is equipped.
Two photos of Eric's premium with the Rally springs. Basically looks like a normal SUV.
Reading up on all this and I might just bite since my car will be going in for some work. These three pieces all an installer needs to upgrade the ride quality and handling?Hi JM,
As you have most likely read in several posts of mine (and others), the best way to achieve a more comfortable ride is to replace your springs with the OEM Rally springs and sway bars with the Eibach sway bars. There are other ways you can soften the ride a bit but nothing will do it as much as the OEM Rally springs and Eibach sway bars. It is important to change the sway bars at the same time because: 1. The Rally springs soften the ride and the handling will suffer a bit. The Eibach bars will bring back the handling and then some. Car will handle much better than before. 2. The OEM bars have a vulcanized rubber mounted bushing that does not allow the bar to articulate giving a more firm ride. The Eibach bars do not have this mounting setup and allow the car to ride smoother while handling better. 3. Since you have to disconnect the end links of the sway bars to install the springs, it's cheaper for the install labor to do the bars at the same time.
Now, as far as the part numbers you got for the "Sport" springs, those look like manufacturing numbers which sometimes have a few extra letters at the end. The part number is what is listed in the Ford parts catalog that the dealer would order from. The manufacturing number is what is attached or moulded into the part itself. Most Ford parts have a manufacturing number on them. This number is NOT the part number although it may be very close and sometimes not even close at all. That said, the manufacturing number you have for your rear "Sport" spring is the same as the Rally rear sport spring but the front is one digit off. I am thinking those "Sport" springs might be the same as the Rally springs but I cannot say for certain. If you look in John's first post of this thread, he lists the exact measurements of the springs that I took. You mentioned that the parts person did not know specifics of the springs and that is true. None of the dealers have any specific info on the springs.
The person on eBay that told you certain springs would not fit on your car, they are wrong. As you assumed, any Mach-E springs will fit and work on your car but I would not be buying springs from them anyway. You never know what you will be getting when it comes to something like springs. I would only purchase directly from a Ford dealer. As a side note, I have shipped many items to the UK (and Europe, Asia, Australia for that matter) so if it comes to the point where you are having issues getting the correct parts, let me know and I can find out the cost of shipping the springs.
I have a set of Rally springs here because I'm installing them in a member's car this weekend (my 4th Rally spring install). It just makes it easier if they ship me the springs since we do the install at my home. Below is an example of what I was talking about between the part number and manufacturing number.
Front Rally spring part number tag. This part number tag is attached to the spring for shipping purposes only. All springs are shipped from the springs manufacturer with only the manufacturing number tag.

Bottom line, you need these exact PART numbers for the Ford OEM Rally springs and Eibach Sway Bars:
Quantity 2 - Part #: RK9Z-5310-A (Front)
Quantity 2 - Part #: RK9Z-5560-B (Rear)
Eibach Sway Bar kit Quantity 1 - Part #: E40-35-054-01-11
It depends on the scope of what you want. Mark recommends doing both the Eibach front and rear sway bars at the same time as the front and rear Rally springs. If you have a Mach E GT, you will not need additional parts besides those items. In terms of parts, you'd be buying two each of the front and rear springs, as well as one each of the front and rear sway bars.
Thanks, yes GT here, so guess I’m good! Doing both springs and bars as that seems to be highly recommended. As Mark said, might as well go all in!
Yes those part numbers I have listed that are at the end of the post of mine you quoted are what you need. It’s important to have the sway bars installed at the same time. 1. Because it will be more expensive if you do it later since you are already taking apart some of the sway bar suspension parts to remove the springs. 2. The rally springs are softer giving you more body roll and you want to eliminate that and bring back and even improve the handling and 3. the new bars actually make the ride a bit smoother because of the mounting bushings compared to the OEM vulcanized bushings.
thanks again Mark! just placed the order for the bars and springs after triple and quadruple-checking the part numbers!
Sorry, I forgot to post a link of the kit if you wanted to buy it. I added it to the post.
Thank you very much, adding that to my list! Appreciate you going into detail explaining it all!
If you choose not to do the Eibach sway bars do you still need the camber bolt kit?
Yes absolutely, The springs change the height of the car which will change your camber. The bars do nothing for the height so even if you were to put the bars in later, you would not need to change your alignment.
