98 Trooper with OME 912's and torsion crank with 265/75/16's. Driving to work yesterday I saw someone on the side of the road changing a flat and thought....Hmmm...If I got a flat would the stock jack have enough lift to pick my slightly lifted bigger tired troop off the ground? <img src="/forums/images/graemlins/confused.gif" alt="" />
I thought about pulling it out and giving it a shot but it was 3 degrees here in Denver yesterday and not much warmer today.
So... anybody here find that a stock jack is too short with a lift and bigger tires?

BTW I do have a Jack-all Jack (Similar to Hi-Lift) in the garage,but with no slider bars I haven't found any lifting points I could use with out tearing up my otherwise un modified Troop.

The bottle jack will raise it high enough. Jack from the lower A arms in the front and the axle in the rear.

Yup. Remember, the lift raised the body in relation the axles and other suspension parts and pieces. The only way to raise the suspension parts in relation to the ground is to go with bigger tires. As long as you can get the jack under the rear axle or one of the front a-arm, then you should be able to lift the offending tire.

Kudos for thinking ahead. When you get a chance, try it out to make sure you have enough lift in the jack. Easier now under controlled circumstances, than the alternative. I don't know what the later model Trooper jacks look like (scissor or bottle or ???) but some of the newer vehicle jacks are for only lifting off of body seams or other specific lift points. The are not for general lifting. If that is the case you may want to go and purchase a reasonable quality bottle jack. You may also want to consider buying a bottle jack because the screw type bottle jacks can be a real PITA sometimes.

Good Luck,

On our '92 the stock jack won't quite get the tire off the ground. But it's easy enough to stick something under the jack. <img src="/forums/images/graemlins/notooth.gif" alt="" />

you can get it off no problem w/ my lift and tires i can still jack from the front cross member low points, no problem form the control arms or from the axle, it just takes a while cause the jack get's pretty close to it's top, i know i know it's unsafe, but it can be done if you're wonderin

FYI, none of my troopers (95, 95.5, & 01) would lift a rear tire w/ bottle jack. I carried 2 2x10s boards and a piece of aluminum plate. Extra 2+ inches were needed after lift and 285s. IN all cases, I tried to use the jack from my '01. It may have had a reduced max lift height.

I know the one in my 92 Rodeo works really well. For a while there that was the only jack I had around to do any work with. On a side not. My friend has a cherokee that has almost 31" tires on it. One day on our way home from school, one of his free bald tires decided to start letting go. So we pulled over, and found out the jack was too short. So we ended up using 2 our text books to support the jack till he could put the "donut" on. Looked rather funny with 3 265/75-15s and one 215/70/15. So if all else fails make sure you have a few bricks, pieces of lumber or a couple thick text books.

sorry, bout my previous post, uh well, i guess i assumed that the jack would work in the back, but i never tried it, i thought it'd work though, guess the added travel of the OME's makes it hard?

If your lifting from the axle the length of the springs does not matter. The only factor here would be tire size.

Weird, I figured you Trooper guys would have a jack at least the same size if not larger than my 99 Amigo. I posted making that assumption. With 32" tires my bottle jack will lift a tire plenty high on all 4 corners.

I pulled out the jack last night to see if it had the fully extended and fully compressed dimensions listed on it but it didn't. Sorry if I mis"spoke".
