Correction bracket question

[Gren71]

I have a set of rancho geometry brackets i want to put on after my 2in lift.

https://www.jegs.com/i/Rancho/801/RS62118B/10002/-1?year=2020&make=JEEP&model=GLADIATOR&submodel=SPORT+S&engine=V6+(+3.6L+/+220+)

currently i have the MPP LCAs back on with the brackets

my question is should i stick the oem LCAs?

my goal is to get my caster back as well as get the correct control arm angle. But don’t want to over correct caster.

the brackets just put the front control arms back at the right angle after the lift, which as far as I understand doesn’t change the caster. So if i keep the MPP LCAs my caster should be back to spec.

I don’t have a flat surface so i csnt measure the caster my self. And it takes a while for an appointment at any local shop so i cant just run and get the alignment checked without an appointment

appears these have bolt holes for 2, 3, 4" lift adjustments. The AEV bracketes have washer that is stamped offset. The orintation of the washer changes the adjustable for lift height. But these have the 3 holes to move the bolt up and towards the rear for adjustment

edit: I would use both together

I believe they do both, correct caster and restore the control arms being parallel to the ground, I would try it with the Mopar control arms, the difference is pretty minimal.

Like others above said, I think you will be fine with the Mopar LCAs. I'd set it at the 3" mark and see how parallel to the ground they are.

The instructions are as straight forward as I figured, shouldn’t (famous las words ) be a difficult install.

The instructions say to get an alignment… correct me if im wrong but these shouldnt have any effect on my toe right? I JUST reset it and its perfect..

my limited understanding tells me it wont have any effect but just wanted to see if im dead wrong.

and as for caster, i can see that being adjusted a little since ill try this with the mpp lcas.

as a side note…whats a sign of too much caster? So I know what to look for if i need to swap back to oem lcas.

You don't need an alignment.

I wouldn't be bothered having 7 deg of caster, the effort to turn the wheel off center will go up as caster goes up. We have power steering, we don't autocross against Miatas, who cares? Plus, super steady straight ahead when towing is a FEATURE, not a bug.

Since NO lift on the JTR with the Mopar .25" longer arms only got me to 6 deg of caster, I would figure 2" of lift on a Sport with correction brackets set to 2" would get you 6.5 deg or so.

Factory range of 4.5 +/- 1 deg is CRAZY shallow according to my suspension shop. I think you'll be good to go.

All done and torqued up. It was pretty much exactly what I expected as far as the install… Really not that hard.

here is a concern that I noticed though… With my Wrangler Unlimited I ended up having to replace the front driveshaft after the boot ripped because of the driveshaft angle. Looking at my front driveshaft it seems like it’s at the same extreme angle… Which is not cool

Any picture before the drop brackets of the driveshaft angle? I would think the original control arms might make the angle a little better, as the pumpkin would rotate up a little.

Is that the transfer case side? does changing the angle even effect that? Seems like suspension lift would be the only way to change the angle on the t-case side, no?

Unfortunately no, i didnt eve think it would be that way until i just happened to see it while rolling around underneath the jeep.

i was thinking the same thing with the oem LCAs. But the difference between the oem and the mpp is so dang minimal im not sure its worth it.

Also adjusting the UCA to of of the lower holes on the brackets would also rotate the pumpkin a bit.

My guess is that angle is entirely because of the 2in lift.

but i could be completely wrong haha

Yep thats the t case side. And the lift is also my suspected culprit.

it’s not quite as extreme as it was on my wrangler. But it just seems like an inappropriate angle for where the driveshaft connects to the transfer case.

If someone else has a moment could you snap a picture of yours so I could compare?

 

[Mac]

Would be helpful if someone with a 2” lift could post a picture of their driveshaft angle, I have a 1.5” spacer I can take a picture for comparison.

 

[Mac]

Picture of mine, 1.5” spacer with 340 and 343 springs, been using this setup for 15k miles.

Well thats comforting to see its not that abnormal. Ive had my lift on for 35,000ish miles, and had 1.5in spacers in the front before that. I took a good look and didn’t see any signs of wear or damage, so it may just be me being paranoid. Ill keep a close eye on it going forward.

How does it drive now? Notice much of a difference?
