How To: Trunk Strut Install (No More Torsion Bars

Here is my simple write-up on how to install struts to your trunk so those annoying torsion bars will be gone. I bought the struts for AutoZone for about $20 a piece (lifetime warranty). They measure 14" when extended fully and around 9" compressed (the black chamber is about 8" and the shaft is about 6" when extended). I have two numbers that I got off the struts and they are 29306 and 4259, I don't know which one they use for part look-up but I think it is the 29306. This strut has and open end (looks like an eye-lit hole) and the other is where you snap it onto a bolt with a ball on it. Make sure when you buy the struts that you have the one with the removable ball (easier intall).


1: The first thing you have to do is remove the torsion bars.
2: Then I bent the torsion bar holders connected to the rear deck out of the way. You can saw them off if you like but every mod that I do to my car you can return it back to stock.
3: Then you want to remove that hanging piece off the hinge arm. Just get a drill or side gringer and remove the rivet type connector that holds the piece.
4: Then you install the parts listed on the PARTS FOR HINGE drawing. The place where you took off the hinge is where you would install the bolt which is about 2" long, washr, and bolt for now.
5: Remove the back seat of your car and the plastic liner in the trunk.
6: On the trunk wall in the upper corner of either side with two holes right by a semi-U shaped opening. That is where you will mount the parts for the back wall. (the pic is named PARTS FOR BACK WALL) Kinda tricky to get in.
7: Once you have all the bolts and bolt with ball installed, all you have to do is install the struts. First I installed the struts to the hinge first and put the closed nut on. I thought it looked better with the closed nut and you don't have to worry about how tight you tighten it because it stops turning and leaves enough play for the strut to move. Then I just snapped ball end of the strut to the wall with the bolt with the ball.

Total mod cost about $45 which includes 2 struts and all bolts and nuts needed for installation. If you have any more questions and don't understand some of the instructions just PM me so we can talk. It is kinda hard to explain everything by writing it so if you want to ask me questions via phone just PM and we can exchange numbers.

I hope you like the install so now on with the pics.

The part that I removerd from hinge



Parts that you will need for hinge.





You can see where I bent the old torsion holders out of the way. Like I said you can cut them off if you want.

Install this part to the back wall. The actual pic of it install is kind crappy but you get the general area placement of the bolt ball.








Now after you have bolted all the pieces in you first secure the strut to the hinge then snap the other end of the strut tot the back wall. Now pics of the completed install.






Once again if you need help just PM me. Also I am not liable for any screw ups you do and this installation is at your own risk.

this is a dumb question, but how the hell do you remove your backseat. that seems like more labor than the actual installation of the struts.

You might not have to if you can just bolt it through the hole in the back wall (see picture) There is just more room in the cabin if you need.

Subscribing.

It still sucks that you have the arms in the way. Nissan cheaped out by not just using a hinge design.

When you open the trunk lid, does it pop all the way up with some force? Also, does it affect the alignment of the trunk lid? Does it require lots of force to close securely? I tried a version of this mod with only one strut but I didn't remove the torsion bars. I didn't like it so much and when I removed it the trunk lid gap is slightly large on the side where I had the strut.

White Shadow the trunk opens like factory, real smooth and no gaps or anything. If you follow my directions then it won't pop up on its own. It could though if you lower the position of the strut on the back wall.

haha i was just thinking about only one negative about this, not to put a hinder on something that i can't wait to do. The only problem I could see is if you accidentally hit the trunk opener with your elbow and your automatic trunk lifter fights the wind while you're driving and works.

...heck, i'm doing it anyway.

Im just a bit confused about the back wall? Where exactly does that ball nut bolt on to the back wall? From the pics the strut just disappears into a dark hole? A little help needed thanks.

Good job on the install. I forgot to mention that I have a lot of Dynamat on my trunk so my trunk does not pop up automatically, but it looks cool when yours does.

You should be able to do it without compressing the strut. I did it before on my 4th g.

nismos14 probably drilled different holes to accomodate for the specific struts he bought. All we/I did was use existing holes and used a strut as close to the length as possible. It was hard but I did it by myself, Air Force push-ups help.

Well, for those of us who are not very strong and didn't have other people around to help... I suggest a way to improvise



Using this method I was able to compress the strut enough to clip it on to the ball. However, if you do attempt this, be careful as it does go under a fair amount of tension and you have to guide it to push against the strut! I think the struts I installed are 380N. It is a dangerous way to go about it, but I didn't really have any alternative.

One problem I've found though, is that my bootlid doesn't automatically come up when I hit the boot release like 2AZN2DMAX's boot does

do you have any pics of where you mounted the struts on the seat side of the trunk?

Certainly do



The ball in the distance is where I mounted the strut, as advised by 2AZN2DMAX

I couldn't find a strut that accepted a 'clip in ball' mount on one end and a hole for a nut/bolt on the other end, so I have the ball/stud on the boot arm as well.

As you can see in the pic below, I can't mount the strut any lower, as the boot lining would need to be cut up (something I'm not too keen on doing!)
