I was thinking of starting a post with this same question. I would like to know as well please.

If you look underneath either of the upper control arms, there's a bumpstop bracket with an upward facing snubber (small black rubber bumper). If the torsion bars are cranked up as far as most people tend to, the bottom of the control arm will be in contact with (or worse, compressing) the snubber. This leaves your suspension at full droop, without any further down travel possible. You can also check the length of the torsion bar adjustment bolts, from the top of the nut to the end of the bolt, should be a specified length at stock ride height. I found this in my repair manual, "tighten the adjusting nut so that the exposed thread is no greater than 87mm". That number is for 86-88 Pick-Up and 4Runner-4WD. I'm assuming that's supposed to represent stock ride height.

Stock height is 13.5-14" from fender lip rim. Here are some instructions on adjusting.

Would the number from the fender to the rim change with size of tires? I'm very interested in how this is going to work. I'm thinking about some spacers and want to known if it's already cranked so I can bring them down some.

try the bumpstop thing and emasure the bolt sticking out past the nut. the height would change with different tire size

yes, basically a size increase of 2 inches in diameter over stock will net you about 1 inch in lift, i say about because tire pressure will change this.

Whoa!! Let's clear a few things up:

The rim-to-well measurement is not affected by tire size. It is only affected by torsion bar adjustment and weight of the vehicle.

Not sure what post you're responding to, but as stated above tire size has no implications on control arm position, as it relates to the rest of the vehicle. Yes, tire size will lift the entire vehicle, including control arms, knuckles, ball joints... by half the increase in diameter (approximately). But putting bigger tires on will not change the rim-to-well measurement.

The most accurate & consistent means of measuring is the rim-to-well measure. Your bolt lengths can be different. ONLY the ENTIRE vehicle height is changed with tires.

Frank & I said RIM not TREAD.

drguitarum2005

heres a classic example of me misreading the original post. i thought the entire time the original poster said tire to well, not rim to well. my fault. deleting that post for irrelevency

seanz0rz

for some reason i read it as tread also, my fault.

Or by the rust having eaten away the fender well...like mine.

I think it's pretty reasonable to expect that the shocks would be worn out after 20 years or so.

this is a great thread. thanks for answer my question 86Original. I guess I'll find out tomorrow if my torsion bars have ever been cranked. I hope that they are stock. I have a feeling they are since the original owner only used it as a commuter truck.

Thanks for the Info
