Okay, my torsion bars are cranked up and I have lift blocks in the back, but I want to take the blocks off and take some of the preload off the torsion bars, how much do I turn the bolt for the torsion bars. Plus how do I remove the blocks from the leaf-springs. Do I have to jack up the frame while I remove the bolts to the leaf-springs...??? Can I use an impact to put the bolts back on? Do I need to replace the nuts or u-bolts?


I plan on adding BJ spacers and longer shakles to make it the right height again, just not right now.

I almost cried when I saw the thread title. We've had a couple threads in the last few months with people wanting to lower their 4x4's.

I would take the blocks out, and then uncrank the torsion bars, and keep playing with them until you get it lowered to the proper height.

As far as removing the blocks you're going to want to support the truck along the frame, and take the load off the springs. Then you should be able to remove the u bolts and blocks.

Off the top of my head I think you're going to need new U-Bolts that are the stock length as opposed to the longer ones that go with the blocks.

I did too, glad to see it wasnt what I thought!

i almost did too

Sorry about the scare, but it really is what I am doing theoretically...I also thought that it would get extra attention like this...hahaha

I want a smoother ride... I know that this thing is never going to ride like a lexus, but I would also like some more downward suspension travel in the front! Should I remove the back blocks first and just wing it and lower the front a bit at a time, and just see what looks best, should I make it level or have the back sit up a little more??...when lowering which way should I turn the bolts?

MMA_Alex

to lower you loosen the bolts. rightey tightey, leftey loosey lol. The back should be sitting just a little higher than the front so that when you put a load in the bed you level it out

Sooner or later I will put some BJ- Spacers and extended shackles on it to get it to this height again, I like the look of this height, bigger tires will help fill it out, I just want a better ride and some more downward suspension travel!

You're not lowering it, you're de-lifting it!

Hahaha, good term!

i wouldnt use an impact gun to put the bolts back on. if you do, do NOT start the bolts with the gun, if you have them cross threaded, itll put them on a long ways incorrectly and youll have bigger problems. i would do it all by hand and crank it down real tight with a torque wrench or breaker bar.

MMA_Alex

I agree with not using an impact gun, but you want to make sure you torque them properly instead of just getting them as tight as possible. Its always helpful to use loctite as it will help keep the bolts tight, and make them easier to remove in the future by preventing the threads from rusting.

Actually, from what I've observed, most 2wd trucks sit higher in the back where as most 4x4's sit either level or a little taller in the front. This is normally caused by the rear springs being real stiff (2wd) for towing/hauling or a little softer (4x4) for more travel.

In order for the lspv to work correctly on our trucks the rear has to be very slightly higher than the front, or at least thats the way it is on my truck.

From what I've seen most trucks tend to have the rear slightly higher than the front when unloaded.

lowering the torsion bars will take many tries. lower each side the same number of turns, then jump on the front bumper a bit and measure from ground to top of wheel well. Keep repeating until they are equally adjusted to a height you want, then take it for a drive and hit some bumps. The suspension will settle into place and the sides probably won't be equal anymore, then you have to re-adjust. You might get lucky, or you may have to repeat this a bunch of times.

ok i know i talk alot on this site but ok i get it he is "de-lifting" his truck is there a cheap way ot lift your truck like rase the bars up front and block the rear with something and get very good u-bolts and a ceap set of longer shocks?cause i wanna lift my truck so bad but im broke!

Injohneer

okok there are relatively cheap ways to do everything, but there are only free ways to break your truck and what youre suggesting is severely limiting the capability of your truck especially since it would be taller. if you're too broke to do it safely and correctly dont do it cauze you will break your truck even worse and then not have money to fix it. sell your truck and drive a geo metro. then just ride in your friend's trucks!

And for cryin' out loud, learn to type!
