Floor Jacks and 4x4's
Ok so this Race Jack Skidplates from Ruffstuff! - Pirate4x4.Com Bulletin Board got me thinking how practical is a using a floor jack on a lifted truck?? Obviously its being done or there wouldn't be a need for it; But I'm having a hard time seeing a floor jack with 17.5" of max lift being able to effectively pick up a lifted truck enough to change a tire....

I have no trouble changing 39.5s on George with a regular 3 ton floor jack. I think Karl is doing it with a 2ton bling daddy aluminum jack with the same tires.
the truck really only needs to get an inch or so off the ground to change the tires.

If you divide the tire height in half, say 40" equals 20" from center of hub. Jacking point is lower than that, add in the height of the jack at full down and it doesn't take near as much lift as you would think.

i'd imagine i could change up to 44's with my 3 ton, but probably not a set of 49's. it does handle 40's no problem.the passenger side front tire can be a hassle sometimes.
i will throw this out there though: if you have tires bigger than 35'' on your truck stop dicking around with 2.5 ton jacks. i have killed 2 of them, and luckily got away unharmed. they may be rated at 2.5 tons, but the higher you extend the jack the weaker it gets and the frames decide to taco. no bueno.

High lift jacks can worry me a little to when lifting a whole truck.

We where changing out a dana44 for a 60 tonight, the 6 ton jack stands were just tall enough at there highest setting on the leafs springs. three ton floor jack did just fine with the 37s on the 44,and 40s on the 60.
I do need to find some taller jack stands.

Edit, sad news is I lost my jackstands. We cut the tops off to make them into crab cookers!

on the topic of jackstands. What do you think about using rims. I was just given 8 old steel rims and was thinking of throwing a couple rods at them, welding them lip to lip for jackstands when I pull my rear axle. Just cant figure if the rim lip is strong enough for the side load.
