Cribbing

[bszopi]

So, I'm thinking of making some cribbing to raise the Mustang off the ground solidly while I work on it. As of right now, I'm thinking of building a pyramid-type structure out of 4x6 lumber. Bottom 2 pieces would be 24" long, next 2 would be 18", rotated 90-degrees, and the top 2 would be 12" long, rotated back 90-degrees. I have thought about adding 1 more 12" piece perpendicular to the top, to raise it a little more. The 3 lower levels would be set up in the taller dimension, while the single top piece would be set up in the wider position. I need to draw it out, but what are some thoughts? This should elevate the car ~19" above the floor. All the pieces would also be bolted together to ensure they don't come apart once the car is set down on them.

saw this awhile back while browsing nastyz28.com looks like he used 2x4 lumber which would work out for me since i got some extra 2x4's in the garage. i would like to build them since it will make working under the car way easier and i can have the car level.


don't know if non members can see the pics but the rest can be found here.

the OP said he saw them on this site Detroit Speed & Engineering but i couldn't find any pics and the links they referenced don't work anymore.

Interesting. I plan on supporting under the frame with the wheels off, but that still seems like it might be an option.

found later in the thread he used this much materials 10 - 2X4's total ...... each crib is 14" x 12" which works out because i think i have exactly 10 2x4's

Here we go...

Problem I see? Way too much room taken up, for something that can be built, or bought, and adjustable. Get some good jackstands. When you are done with them, store them, or sell them. The wood goes into? Just sayin'.

^ agreed.

while the structure you posted is very strong in design you have to take into account for the material it's made out of. I'd never trust my life to 3000+ lbs on a Pine 2x4. a good set of jack stands is more than enough. I have a pair that extend to about 2.5' and they provide excellent height and are very sturdy. No latches, just a bigass pin.

The structure I showed was going to be built out of 4x6s, not 2x4s. I personally wouldn't use 2x4s either. I'll have to look around for jackstands, as I don't want to get some cheap ones, as I wouldn't really trust those anymore than 2x4s. I have 2 sets already, but only 1 set I would trust to support a vehicle for an extended amount of time (we are talking years here), and not sure how high I'd want to go with them.

I used 2x4s exactly like what are under that SWEET Z28. I made them wide enough so the feet of my jackstands sat ~2x2 from the outside corners of the cribbing. I did this because of how far off of the ground my truck is compared to how high my jack stands goes. I had the wood sitting around but lacked the $$$ to buy big jack stands and I had something I needed to get done and my current stands were not tall enough (I don't even remember what it was now, TBH). I still have the cribbing and it takes up little space. I liked the flat design I used because if the truck accidentally got bumped somehow, the cribbing wouldn't collapse with me under the truck. It was just as sturdy as stands sitting on the floor.

i got a couple sets of these awhile back

and a couple of smaller ones. i'm not lacking jackstands.

are you looking to use the cribbing like jackstands or put it under the wheels like in the picture i posted.

little pricey but 30" is very nice. You'll also need a jack that can go that high though.

I think i bought mine at Autozone, they are 6 ton rated and the camaro has been on them for a few weeks now. it doesn't even move if you shake the car around.

The cribbing was going to be under the car, like jackstands. The whole point is so I can get the car up off the ground to work underneath it, with the wheels off. I'll have to look when I get home, but I currently have a set of Craftsman 2 ton and a set of Craftsman 5 ton (not 100% on the ratings). I hardly ever use the 2 ton ones, just because they just don't seem as sturdy as the 5-ton ones. When I was young, and working on cars with my dad, we just useds some old... railroad ties is all I can think to describe them, but into ~12" sections. Would often stack 2 on top of each other at all 4 corners and the car would just sit there and not move at all.

Quick update...

Just found 4 6-ton jacks on craigslist for $40. Be picking them up tomorrow, then I'll get the car elevated in the garage properly.

[RednBlack]

Glad to hear that. How high do they go?

[bszopi]

Not sure how high, but they are almost 15" at their lowest setting. Definitely worth the $40 plus the 2hr round trip to go get them.
