Auto Trunk Support Lifts

[Vuuduu]

1 3/4 - 2 1/4 is the best length for the helper spring but the strength / compression is the spring is key factor.

The regular spring I bought had the near exact specs as the spring you bought. I’m guessing my strut is different length than yours because even with the trunk near closed, the strut isn’t even close to compressing the spring. In the video, you can see how much length I needed just to get a good compression.

I’m returning the struts for the some similar to BadOne’s. It’s going to be 17” instead of 18”. The ones I previously used were from Amazon..

With the shorter length and stronger weight support, I’m assuming the blue die spring should work better alone. Seems 100lbs is strong but not enough to push open alone without a very compressed spring. I’ll play around with the spring setup again once the new struts come in.

Just want the jiggle to stop when fully extended.

Perfect solution now imo. I went with the shorter springs (one on each side) in the 1 3/4” length. Specs are listed in the image. Super elated with the end result.

Hey man, do you mind posting links to all that you purchased to make this work?

Just wanted to add:

I just installed these:

https://www.liftsupportsdepot.com/1...th-10mm-ez-release-ball-sockets-pm3667ez10-w/

They work great with the Streethunter Wing.
Doesn't auto-lift from the button push, but once you lift it past a certain point it does.

No weird shaking around at the fully open position either.
It perfectly slows down toward full open.

The quick-release bits made doing the install really easy.

Thanks for chiming in with your experience! Your linked struts are 150lb, one of the highest I've seen in the thread, but they seem to be well dampened so they aren't just launching that force into the car, do you feel like they are indeed super strong? Are you going to try with some springs to get over the initial lifting?

The trunk definitely requires a noticeable amount of extra force to close (to be expected, there is more force lifting the trunk).
I wouldn't use one hand on the plastic pull down spot, but it's still very closable with 1 hand, and you can use 2 hands if you want to use the plastic pull down part.

I'm definitely waiting to see how the springs go here before trying them out.

Yes, please.

Wait until you see how much a totally not even needed catback costs.

BUT IT SOUNDS GOOD

Update for y’all. Here are specs of my final solution. The shaking at the end isn't as rough as the video shows. It will pretty much go away once the struts and springs settle in. Specs below:

• Struts
• Springs (Required Qty. 2)
  • Other Optional Springs in lieu of (Required Qty. 4)
• Washers - M8

Struts:

• Extended Length A [in]: 17.00
• Stroke C [in]: 6.80
• Compressed Length B [in]: 10.25
• Force (Lbs): 120
• Force Newtons: 534
• Shaft Connection: Quick Release (Nylon) =10mm=3/8"=.39"
• Body Connection: Quick Release (Nylon) =10mm=3/8"=.39"
• Rod Diameter (MM): 8
• Cylinder Diameter (MM): 18

Spring (Qty. 2):

Spring (Qty. 4):

• Length 50mm
• Inner Diameter 8mm
• Outer Diameter 16mm

Whats the optional things? I think the link is wrong

fixed the link. It’s just optional spring in lieu of the main one.

Struts and Springs are same link.

fixed the link. It’s just optional spring in lieu of the main one.

I clicked on the link for the main springs and it took me to the struts page. You satisfied with how it turned out? The springs don't make it too forceful when opened? I think I will try it out.

Sorry guys, don’t know what happened. Fixed the links in the original post. Don’t click the ones in the quotes.

When you initially install, like my video, it seems a bit forceful/jerky. It’s because the strut and spring are new and haven’t settled. (The trunk has a long range of motion, which allows for additional vertical movement, so the jiggling/vibrating you see in the video isn’t really harming anything.)

After some time, it won’t be like that anymore. I opened the trunk earlier at dinner to show a friend and it opened just fine.

My earlier experiment with different springs ended up not opening the trunk anymore after settling in. That’s why I opted for a more robust spring (die spring) and a stronger strut.

Overall, I’m pretty satisfied with the Lift Depot struts.

Ordered, springs say arriving aug 1st - aug 18th... hopefully thats a bit exaggerated?

Ordered, springs say arriving aug 1st - aug 18th... hopefully thats a bit exaggerated?

I found some 16mm x 100mm die spring options for you if you don't want to wait. Dimensions are the same and the max load is around 45lbs per spring which is plenty.

Option 1 - Qty. 5
Option 2 - Qty. 2
