Rock guard & hi-lift jack use

I don't know what kind of step/rock guard I have on my 4runner but I want to make sure it is safe to use with a hi-lift jack. I just put on a lift and bigger tires so the stock jack won't cut it.

The rock guards are mounted into the side of the frame (I believe... see photos).

I attempted a practice run of jacking up the 4runner with a hi-lift jack in the driveway and the step/rock guard started to pinch closer towards the body. I lowered it back down when I saw that. Is that normal? Safe to proceed?

 

Sorry if I didn't understood, you meant to say stock jack don't work any more after lift and tires?

My stock Toyota jack still works with 3in lift and 285/70R17s.

Additionally I have 48" hi-lift with offroad base if I have to use on a trail and works well with my RSG sliders.

 

I have to agree with Overland Charlie. Unless you really know how to utilize a high-lift jack, you can do a lot of damage, or worse yet get hurt. Be wise and use equipment that is easier to use when needed rather than getting a so-called wonder solution that can go wrong if not well versed in how to use it.

 

My stock jack didn't work on my 265s without a lift. I maxed out and was BARELY able to get the tire off. Now I have 285s with a lift 2.5" front, 2" back. Are you putting anything under your stock jack?

 

No I didn't use anything under it. Too bad I don't have any pic when the wheel is lifted. These are the only tools I was using to lift my lifted Limited testing my spare 285 for fender liner trimming.

You are using the correct jack points right? Rear I use on the axle and front I use the frame closest to the lower control arm. I think its will be same on my TRD ORP as well. Too bad its too cold to test.

 

I agree with others that a good bottle jack or floor jack is safer than a Hi-lift in many situations.

However, it's a good tool to have. I used mine on a trail when I was high-centered in some rocks, and it worked fine. Of course, we were EXTREMELY careful about everything.

I have RSG sliders, and they did flex towards the body. I'm not sure if it touched, but I haven't noticed any damage.

 

Another 2cents worth here. Hi-lift jacks are good if you are familiar with their eccentricities, like letting go at the wrong moment and removing appendages not to mention vehicular damage. Carry one if you have to but keep it clean and lubed so it operates smoothly. Practice with it on occasion. Your best and safest bet is to use the old bottle jack with a solid base to reduce sinking in whatever you are parked on. Better yet is to travel with friends who can pull you out using your snatch strap/rope or winch.
Have fun!
