Frunk & rear decklid holding shocks
OK so I have replaced ALL frunk and rear decklid holder upper thingys with new ones from here and they don't hold stuff up. Is there a check valve plug on them or something I am missing? Seems odd a simple pnuematic shock would be finicky but what do I know??
Anybody have input? |

I bought a used set of these from a forum member, they work well but don't "pop" when the latch release is actuated so you need to make sure that the adjustments are spot on. I added a little string to the frunk late as a safety measure.

Any chance these were installed in the wrong direction ?
The beefier piston section should be attached at the hinges and the thinner rod goes to the stationary or fixed body mount. |

I think you are both referring to the same orientation. Thick part on top, on the articulated panel. Thin part attached to the car body. IIRC, it's so the oil will pool around the seal and keep it lubricated.

Thick portion of the struts to upward. Here's pretty good video with some tool tips to help the painful task of installing new ones. The driver's side is a major PITA!

I've been through this before, replaced the struts with the heavy duty versions, only to have the frunk fall on my head again after a few years. The mechanical ones (referenced in my earlier post) work great!

I tried the one Rennline and one regular shock/strut too. It worked, but the Rennline strut holds the frunk lid about 6-8" lower than the pneumatic supports. I was always whacking the back of my head on the hood or latch.

Interesting idea to use one Rennline and one gas shock, might help with the missing "pop" when the latch is pulled. I've never been concerned with forcing the frunk closed, I'm the only one who opens and closes it and know the trick to get it unlatched. I do agree that you need to be careful once it's unlatched, the full weight of the frunk will come down if you don't hang on and let it down carefully.
