Harbor Freight has rubber pads that fit their jack stands perfectly. Protects the undercoating well, and is literally made for the job. Fit my old jack stands okay, and were fairly cheap.


Glad to hear you were not crushed by your car.

I recommend sturdy light concrete blocks instead of jack stands.
- or alternatively large wood blocks

Played my own share with jack stands, but for 15 years have used big wood blocks and light concrete blocks.

It is okay to play, but not with lifting a car.

Maybe you have special Finland concrete blocks, but our standard US fair concrete blocks should not be used to support a vehicle. They aren't built for that kind of load.

I have seen several crushed concrete blocks under vehicles. Definitely a No-No. They would be the last things I used. Even then, I wouldn't use them. I even had one fail under my boat trailer - weighs way less then my cars.

Have used blocks similar to these:
https://www.talotuote.fi/HARKKO-RUH-290

4MPa, so it will take about 68 tons per block. Mind you, if you'd place a sharp object between the block and floor, the block may crack, though it will not disintegrate.

On a nice and tidy floor I'd prefer to use wooden blocks, as the light concrete blocks bring a bit of dust.

Chains on both rear mounts ?

Can the car still slip off the front jacks ?

Yeah, definitely not concrete blocks as the others have said.

Wood is fine, that's what I use to support and brace the tires whenever the car is up.

About six years ago, I made a set of my own wood block supports out of 2"X12" boards that I screwed () together (sizes for chassis support points and also to go under the wheels when I want, for maximum height) - all are stackable and I even put sturdy handles on the sides of them so I can easily move them around (big and heavy, obviously) - I also put rubber matting on some of them. I got the idea when I saw old-school pics of race teams using wooden blocks for supports. I have never felt safer under a vehicle.

Large chunks of wood is always good. Mind you, as years have passed, I now need both hands to hold morning wood down.

Yes it is about being safe under car, also like to add something underneath in the middle, just as a precaution.

Since people like pics (not of Highway's two-handed morning wood, however!!!), here is what I was babbling about.

BTW, even though there is no problem with it, I would not work under the car when it is supported with the 2X4 section on the lift point - I always put supports under the wheels if I'm going to be under the car.

One pic shows the wheel support size under the rear control arm - works great there when max height isn't necessary.

The knockers on the wood are a nice touch.

If you're thinking of the concrete masonry block aka breeze block they are a definite no!

yes both, with tension taken up but not lifting off the jack stands. It would take a pretty good push to take it off the front stands, the only reason the front one moved was because it slipped off at the rear

I'm still feeling sick about the whole thing.

Scary stuff. I use one more jack stand than needed just to be safe. So 3 if I’m using 2 and 5 if I’m using 4.

For supporting large turbine parts we use oak timbers. We do not use pine since it’s more prone to split but the wooden blocks above look pretty seasoned.

Yeah, mines on them right now. The late USA cars have nice jack points for them to rest on.
