Do I need to do castor correction for 2-3" lift? (3 Viewers)

[orttauq]

Installed my Ironman 2 inch springs (finally) this last weekend. Before/after measurements come in at more like 3-3.5 so I am trying to determine IF castor correction is needed. I am getting
"If you think you need that much adjustment" when asking about plates. Seems like pinion angle is high.

Please direct me wise ones!

Officially, yes you do. Bushings for sure. Possibly plates. You are in the gray area at 3.5" over stock.

Unofficially I would drive it and wait for things to settle. That's what I've been doing for over a year now.... I'm going to do the washer mod here one of these days.

i know others will say i am stupid but i have a 2.5 ome medium and 1.5 spacers on top with no caster mods. drives fine to me.

i'd wait for it to settle.
how does it drive?

just be careful with crosswinds.

I'm in the same but I've got OME 2.5"heavies up front with 1.3" spacers without caster correction but I wouldn't put any more.

You don't "have" to do a lot of things, but there's no reason not to add it... that's about all there is to it.

I have ome j front med in rear, sway drops, extended bump stops, ome L shocks I have about 65k miles on them with no issues. Crosswinds does move the rig when driving down hwy 5.

I've got OME 850/863 and I find the yellow castor correction bushings inadequate, so if you're asking me, I would say yes, you need castor correction. But as you can see, everyone has their own opinion (probably based on the amount of handling slop they can tolerate personally). So I guess the "drive it a while and see what you think" method is probably not a bad way to go.

OME stock height replacements with 30mm spacer in the front and no caster mods. Alignment rack says I have 0* caster and should be 2-4*. it seems to drive fine. I am planing on going to a Slinky set up in the next year or so, I will worry about it then

 

[JDMark]

Did you install the "Performance" springs or the "Constant Load" springs from Ironman?

 

[mtnzorro]

check your caster once it settles and before you do any sort of correcting. i started off with 2in drop bracket correction for my lift (tjm progressive springs ~2-3 in of lift), assuming that's all i needed. after getting it aligned, my caster was still way off from stock. I then went with caster correction plates and now i'm at 3.8deg. drives MUCH better. if i'd checked it before doing my initial correction, i'd have saved myself the $$ and time on not getting the right the first time. whether you go plates, bushings, drop brackets, etc, make sure you know your starting point.

each rig is different though. i about peed my pants the first time i drove mine w/o caster correction over 60mph and tried changing lanes. i like have mine corrected.

I say you need it. Ujoints will suffer if nothing else.

In my experience, 2" with no correction will give a squirelly feeling on the road. If you don't notice or don't mind and you can drive safely, and if you get no odd vibrations, then you don't need it that bad. Drive it for a bit and then decide.

I have a 2.5 without the bushings and have been driving it for just over a year and want to put them in. mine is all over the road even after new wheel bearings and trunnion bearings. it just seems sloppy to me. this weekend im getting an alignment done and will check then...

 

[richxd87]

I don't think anyone has corrected their caster and regretted it. Sure it drives "fine" without it but the difference is noticeable once the caster is within spec or more.

FYI, a standard alignment on our solid axle 80's only will only adjust toe. Caster and camber adjustments are not available and remain unaffected and would only be measured during the alignment. I've seen a couple of comments above where there was some expection that there would be a change.

Thanks All! I have only driven it around the neighborhood a few miles. I like the new suspension setup so far. I have to get the bumpers back on, spare tire (normal weight) and then I will do a freeway run and see how it goes.

Again Thanks

With enough caster you should be able to drive at freeway speeds with one finger and take pictures

Castor oil is most commonly used to correct constipation. If that is your problem, there are easier ways to deal with it than caster bushings.

I do that with no correction.......... As long as both lanes and the shoulder are clear!
