My two cents on Lift kits

Hi everyone, I’m a certified mechanic, a Ford transit owner, and I’m frustrated with the available lift kit options. I’ve installed a lift kit in my van, but having the front end apart, I’ve discovered some things I want to discuss.

So, here’s a basic run down of the available kits, the problemsI experienced with my traxda lift and the issues I see with the rest of what’s available.

Vancompass has two lift kits. The Subframe drop idea is a crazy amount of work, but gives you perfect geometry. However you gain no effective clearance under the subframe unless you run bigger tires. You’ve merely lifted the van body higher.

Their second lift style is better. 3/4 inch strut spacer, plus a 1 and 1/4 inch lift from a new coil spring. Add those numbers together, you have 2 inches. Then you can also install a bilstein strut, and have a little more.

The problem with their second style of lift, is that struts have a maximum extension. These are arbitrary numbers, but imagine if you measured the strut from the top to the bottom, and it was 24 inches tall. That’s the maximum extension. When the strut is fully compressed, it’s 16”. So you have 8 inches of travel. When the weight of the vehicle is on the strut, it’s compressed somewhere in the middle of the travel.
So you have 4 inches up travel, and 4 inches down. When you add a coil spring that adds 1 and 1/4” to the height, what you’ve done is change where the mid point of the strut is. So you now have 5 and 1/4 inches of upward travel (wheel being pushed up into the fender by the road) but you only have 2 and 3/4” of downward travel. So if your wheel has to drop down into something, it is now has limited downward travel and you fully extend the suspension under a huge amount of negative load. This is really not good for the internal valving inside the strut and gives you a ride that feels like your being pulled back to the earth.

Now the traxda lift actually gives the van the best lift. “Technically” It pushes the van up in the air, adds height under the front crossmember, and keeps the strut at its factory middle. 4 inches up and 4 inches down. The problem is, actually getting everything back together. To put the 2 inch strut spacer on top of the strut, you have to remove the strut from the knuckle. It comes apart really easily, then you bolt the strut spacer on top, and stick it all back together. But the strut won’t go back into the knuckle, no matter how hard you try. The angles, because of adding 2 inches, are to great to overcome, and the strut won’t drop into the hole in the knuckle. So then I undid the ball joint, which allowed me to remove the knuckle from the lower control arm, and gave me the clearance to get the knuckle and strut back together. But then the angles were too extreme to get the ball joint back into the lower control arm..... arrrrrgggg. I got it back together, but had to fix the threads on the lower ball joint. Annoying.

Van compass only used a 3/4 inch spacer, and that is what would allow you to get it back together really easily. Remember that the strut has the same maximum extension no matter what. So that means, you’re only fighting 3/4 inch instead of 2 inch. For the sake of installing a lift, that’s why the van compass lift is better. You are not twisting and torquing on everything, to get it back together.

Foes manufacturing, their lift has the 2” spacer, but it has a modified factory control arm. Because the new lower control arm makes up for the angles of everything, the ball joint slips right in. This is the best solution, but very expensive for what you are getting and if you need new control arm bushings down the road, you have to buy new control arms... this is expensive. So that makes it the worst lift. Repairability is super important. You wouldn’t want to be on a trip, only to find out you need new lower control arms, and the factory ones are all that are available.

What I think the solution is.
1)Keep the factory strut and spring together
2) use a 2” space with camber adjustment
3) make a control arm with replaceable bushings, that deals with the angles that are at their maximums.

Anyways, I’d appreciate peoples thoughts.
Any other people who installed their lift by themselves, I’d love to hear of your experience.

What are you thoughts on a variation of the Van Compass Lift and Installing the Bilstein strut with the Van Compass spring but not use the strut spacer? I'm not savvy enough to understand how the flat 3/4" strut spacer adds camber/castor correction.
It would be nice to see a true lift kit rather than the budget boost/spacer options.

What's FOES life? What's a traxda lift? I thought that VanCompass was the only choice...
Van Compass is the only AWD option.

Don't know who's rock crawling their van, but after a week on the Forestry trunk road the van was able to get me down the dirt trails to all the camp sites I desired and my lift kit is still in the box! Mud and Rut mode works well.

...I have come to terms that some of the camp spots I used to drag my tent trailer into with the LJ are no longer accessible to the van, and I only have 33's.

That being said 245/75 16 AT tires fit with just a small rub on the inside of the wheel well. I'm still thinking of installing Bilsteins instead of using the spacer and using the Vancompass springs. I still can't get my head around what camber correction a flat spacer provides, or is it in the rotation of the strut?

I'm still waiting for the engineers to chime in😁
