Hi, I hope this is the right section for this. I am needing to check my rear flex for new Bilsteins. I don't live near a real RTI ramp or have access to a fork lift (I just moved to CT). I will either have to find an abandoned building loading ramp or a big rock/stump to drive my open diff 5" lifted XJ up.

I saw a thread on here where a guy doing a real RTI ramp got out of his Jeep and because of the weight redistribution, almost flipped it (two of his buddy's help tip it back before it really tipped-and now I am a little paranoid.

If I am driving up a loading do on just my driverside rear tire, for instance, what point is safe to stop further process? Meaning, it seems like most of the RTI pics show HALF of the opposing tire still on the ground, some show just the edge. If I am driving my driverside rear only up the ramp, is it safer to get out of the vehicle to measure flex on the driverside (higher side) or passenger side?

I am really greatfull for your help!

Gee oh Dee

Lol, just go slow.

This is the best advice. Go a few seconds at a time and stop. Don't mash the gas. There's always somewhere to test flex, its just about not trespassing and doing it smart. Test front flex first on said "ramp" so you get a feel of it

Gee oh Dee

Haha I think there is a pic of my Jeep flexed on a ramp with a no trespassing sign in the background.

Yeah go slow and when you feel your back tire just barely come off the ground just stop. There's no need to go any farther, just back down just enough to all have 4 tires on the ground and bam no chance of it rolling over. And you can get out and measure away! Lol

Edit: but that's just my experience...with 4.5" lift. So you shouldn't have a problem then either

sycoglitch

Lol ***, that's awesome

This is true and true rti measuring is with all 4 tires on the ground anyways.

OP either look back alot when doing it or move you mirrors so you can watch what you're doing

Gee oh Dee

Just measure your shock at ride height and subtract the amount of uptravel you have (space between axle and bumpstop) plus about half an inch.

sycoglitch

That's awesome but its page 26 :P

I use this formula to decide what length shock to get for more down travel and not worry about bottoming shock out

SeriousOffroad

Nope, that's bad advice. You haven't factored in tire size or the need for limiting the up-travel to keep the tires from hitting the body, flares, wheelwell.

The best way to do this is to flex the suspension and measure the extended and collapsed lengths.

Short-cuts are fine and dandy until it's your money being spent.

mrfajita

I said that assuming it was properly bumpstopped for its tire size, my bad.

sycoglitch

If he takes into account, the OP, that he is going to have lets say 4" between his tire and the fender then he can still measure the distances to determine. Flexing works the best though

Vincenza V

Great advice. I'll take those tips into account today. Thank you. I'll let you know how it goes.

Go slow. You should be able to feel when you start to float a tire. Thats when you should stop. Or...grab your oh **** handle

I did this and still had another 3" to go up the ramp before my tire lifted but at this point the passenger coil was unseated so there was no need to keep going.
