Jack Height?

[103]

Trying to figure out Jack height I need. I have a 2.5 inch level and 33 inch tires. Jacking off the frame rail, will a 21” max jack height work?

Jack from the axle or lower control arms, not the frame. That'll be more than enough height.

Hi Dustin,

A very good question that has been answered before on this forum. OEM jack may not be suitable for lifted trucks. Check other threads here.

Good luck !

Best,
Phil

Yea the factory jack is useless with any sort of added height.

I have decommissioned mine to use with my wood working when I want to salvage warped boards.

thats genius and cheap.
here i would have gone and bought some celebrity inspired contraption from Lowes at $100 that does the same thing

Those companies that start warning labels with, "This product is not intended for..."

Yea I've mastered the art of ignoring that.

Why such little gaps?

What do you mean?

Seems all the boards are pressed together as tightly as possible.

From my experience (living up north), 3/16" or 1/4" gap is best due to how much swelling wood goes through up in that climate. Least for decks.

I live in a mostly hot place (snow is very very rare), so my wood tends to shrink more than swell. I've tried leaving gaps before and the gaps just get more exaggerated.

Sorry to hear.

seriously though, noted. Its hot as **** down here in southern Illinois so I guess I won't need to leave such large gaps in my wood working.

When I’m building decks, I space untreated cedar deck boards about 3/16” apart. They’re pretty stable and don’t shrink much. I usually space pressure treated spruce only a screw width apart (1/8” maybe) - that stuff is so wet from the mill and there’s definite shrinkage when it dries out. It often ends up being about 3/16” to 1/4” in the end. If the deck is very close to ground level, a 1/4” gap will help with air circulation - important if you want the deck to last in such a damp environment.

So, it really depends on a few things - material, climate, humidity.

Pressure treated wood always shrinks. It's really wet when new. If you lay PT decking as tight as you can, you'll have a 3/16" gap when it totally dries out and is ready to be stained, etc.
