View Full Version : Rear Frame Rail/Jack Stand Interface

I am a bit concerned here about raising the rear of the car on the frame with jack stands. It seems that the frame rail is narrower than the jack stand portion that interfaces with the frame. In other words, not much of the frame is touching the the jack.

Maybe I'll have to go out and by smaller jack stands? Is there a trick to use standard jack stands?

Just want to be safe, so all input appreciated. Thanks.

if your jacking the car in the rear, place the stands on the axle tubes of the rearend, if the suspension is out, then place it on the framerail, I use 6ton stands, because I'm paranoid, :D

set your car on jack stands on a level straight, surface, then try to push the car off the stands, and if it doesnt move, then it should be safe, right now I'm working under my car, I've got 8stands under it, you can never have too many stands

Wow! Paranoid is an understatement in your case!! ;) That's a lot of support!

Not that this is a recommendation but I've had mine on 4 3-ton stands for 4 years. With and without the subframe installed. I climb in and out of the car all the time and have done tons of work underneath. As long as you make sure everything is solid.... the body doesn't rock or move, you're fine.

A bare shell without subframe is much heavier towards the rear. I found that out when I leaned on the trunk. Right now the shell is supported at the four outside corners under the rockers. Each jackstand is on the concrete floor with a length of 2x4 between it and the rocker to spread the load. There's also a small square of short-pile carpet ( the kind used in offices with thick rubber backing) to help keep anything from moving. I also used to put the jackstands on plywood so that they'd dig into the wood and never move. I don't like strictly jackstand-to-concrete contact, or any metal-to-metal contact so I use the rubber carpeting either above and\or below the stands to keep things from sliding around.
