My floor jack won’t get high enough to lift my wife’s Tahoe.
I was going to use a block of wood but then I found these jack extenders in a google search.

Looks like a great idea. Anybody tried these?

Looks "hella" dangerous to me. Doesn't your Tahoe have a stock jack?

Also, moved to Off Topic > Other Cars.

 

Never used it, agree with NismoPick, Looks terrifying.

 

they make truck jacks.

 

better than a piece of wood. if you got some money go to maxjaxx and get the portable hoist, it lifts 6000 lbs and can be moved. i got one and it makes life very easy. i think in the states costco sells them

 

Yeah, definitely dangerous since there is only one point where it is lifting, we use them all the time at work, but there are 4 points of contact, so they won't wobble or look like they're tipping

Is her truck lifted? Also, what are you trying to do?
