using pieces of 4x4 instead of rubber blocks on quickjacks

Can I cut 4 equal sized pieces of 4x4 and use them instead of the rubber blocks to raise my corvette?  The corvette has jacking pucks that sit proud of the body by ~1/2" and while I can slide the quickjack under the jacking pucks when adding the extra height of even the small rubber blocks it just BARELY doesn't fit.  I have done the drive onto a 1x12 to give me the extra 3/4" that is needed but i'm wondering if I cant just cut 4 pieces of equal sized 4x4 and use them in place of the rubber.  I would measure and cut them to be the same size as the recess between where you place the pads and the frame.  

Thoughts?  

The downside of doing that is that they'll tend to split.

Depends on the wood. I wouldn't with SYP, but hard woods would be ok to me. 

Quickjack actually makes a lower profile block: https://www.quickjack.com/1-5-low-profile-blocks/ 

I went out and measured the existing blocks and they measure 2 5/16" so at 1.5" these will be roughly 5/8" of an inch shorter and should be perfect.

Since I don't have a 2x4 piece of hardwood laying around i think i'll go with these.  

Hockey pucks are an inch thick, that's another option.

If you have the ability to cut a 4x4 would you not also have the ability to cut down the QJ pucks? 

I've done it. But im not responsible if it goes horribly sideways on you 

I have used chunks of 2x4 on a quickjack in the past.  It worked OK, but yes, they will have a limited life and you'll need to make new ones eventually.

and Amazon has them by the bagfull.

So do Dicks and Play It Again Sports and Canadian hardware stores - if you don't want to support Amazon :) Heck, stop by your local rink and ask if they have any that are too chewed up for play.

I guess you can take the Canadian out of Canada, but you can't take the Canadian out of the Canadian? ;-)

no...  i would use a sliding mitre saw with a block to create a consistent size, thats easy and safe because the source material will give me a place to hold the material well away from the saw blade but the quickjack blocks being a max of 3" and needing to cut them down to ~1.5" would make it too small to clamp down the working tool and dangerous to hold with my hand.  Additionally the saw blades I have for my sliding saw probably would heat/melt the rubber as they were cutting it.  

however that lead me to discover that quickjack makes a 1.5" tall block and that would be the right height out of the box.

Too true, eh?

The rubber blocks on my old Bendpak scissor jack failed last weekend, so I made these up out of an oak stair tread which is 1" thick, I dado'ed out the slot. I haven't had time to test them yet, so it may turn out to be a complete failure 🤷‍♂️

I have been using 2x4s and 4x4s for 35 years now on my old single post lift and current 2 post, mostly to protect the rubber pads.

If the wood cracks in half, what happens?

In reply to Apexcarver :

Nothing, it's on top of a rubber pad that is probably 5 x 5", they do occasionally get stuck to a screw or sharp pinch seam.

Those look too nice to use!
