Frunk easy close spring mod

[follow.johnny]

Someone posted on the Tesla Forum about finding a heavier weight spring from Home Depot that works with the stock struts.

They noted to use the smaller one in this pack works.

Update: Just finished installing the single spring from the set of 4 (I used the smaller size spring 5/8 in. x 2-1/2 in.) The weight is about 19.4 lbs. Works perfect with stock struts. Took some crappy photos in my garage for the install and how much the hood lifts up with the new spring.

Where did you buy those springs from?

Has anyone tried this on the X or S?

My hood with stronger struts actually failed to open on two separate occasions today after installing the spring (SP 9604) that Brian/i1Tesla used. The frunk opened fine in the garage when leaving in the morning, but after driving 45 minutes on a cool wet day, some part of the hood or latch had stuck a bit and the spring wasn't strong enough to lift the hood up at all. I used a pry tool to lift the hood slightly which was enough for the struts to do the rest. The same thing happened again when I arrived home; hood didn't move at all when latch was released and had to stick a pry tool in.

I just ordered mine as well. Please let me know if you guys use 2 of the smaller/bigger ones from the Everbilt 5/8 in. x 2-1/2 in. and 5/8 in. x 3-1/4 in. Zinc-Plated Extension Spring (4-pack)-16089 - The Home Depot

I used one of the smaller ones and it seems to work really well.

One Prime-Line Extension Spring SP-9610 (0.072 " X 5/8 " X 2-1/2 ") will work perfectly with factory struts.
You can buy from eBay about $3.8 for bag of two

Is it a lot easier to close the frunk with the new spring?

 

[N54TT]

Are all these springs others are using all zinc plated? Are the oem ones zinc plated? Any worries of rusting with the zinc plated springs?

Yeah alot easier! I can close with one hand just by pushing gently over the Tesla emblem. It's works exactly like how Brian from i1Tesa shows in his video (with the exception of the auto open frunk)

You could use the same one that many of us have installed now with the factory struts. It won't be as soft a close as what Brian/i1Tesla shows with the non-factory struts, but it would still be a much easier close than stock, and should be strong enough to lift up your hood since it works with the stock struts. Just use one of the smaller springs from the Home Depot package.

The Home Depot springs are zinc plated, just like it says on the package. The factory one has some kind of plating on it, could be zinc, but it's a matte finish.

I can confirm this as well. Works well.

Yeah, I've already ordered the Prime Line SP 9610 as suggested by fsl2102. As long as it doesn't fail to pop the hood and remains easier to close than stock, I don't mind at all!

For the record I just got back from Home Depot and installed the spring and it's not quite strong enough to pop my frunk. I added some white lithium grease and made sure everything was smooth, but just not quite enough for mine. I left it in for now and need to use my fingers to pry it open until I find a slightly beefier one. I would estimate another 10% to 25% would get me there (about 22-25 lbs). So my PSA announcement for today is that 19 lbs spring will NOT work for everyone....

Which Home Depot spring exactly did you use? The 16089? Short or long?

 

[Leafdriver333]

I just installed Everbilt 685-447 spring from Home depot.
I have stock struts and I like this mod.
The hood pops up a little less than an inch but it pops up.
And it is a lot easier to close.
I can finally use one hand to close it.

Thank you everyone!

Why wouldn't this work for everyone who has the STOCK STRUTS? It's literally the same spring if you brought the correct one.

maybe the hood hinges need lube.

Anyway, what do we do with the left over short spring?
Save it for Model Y, I guess..
