Rancho geometry correction brackets handling change impression

[Mac]

Have had my little lift on my Sport JT for over 2 years, 1.5" Daystar front spacers, 340 and 343 springs, Daystar lower spring perches, Daystar rear .75" spacers, Mopar lower control arms, Rubicon Fox shocks, and Kenda Clever 35x10.5 tires on AEV Savegre wheels. Handling has been fine, okay return to center but every once and a while if I hit bumps around 40-50mph I could feel the beginning of a little oscillation in the steering wheel, especially when cold and the tire pressure was a little lower due to temp. I ordered the Rancho brackets PN RS62118B from Amazon for $175, install was pretty straight forward, installed them with the JT on it's wheels but on ramps on the front, one side at a time used a ratchet strap to hold the axle from sliding forward when the upper and lower control arm when disconnected. The ramp made it easier to retorque the lower control arm bolts to 190ft/lbs. Took about 2 hours. Used the first hole for the upper control arms.
I have run the similar brackets on my JKU in the past.
IMO very noticeable improvement in handling and general straight line stability and no more slight oscillation when hitting bumps around 40-50mph, return to center feels slightly better also. Ride also feels noticeably smoother at all speeds. IMO definitely worth the cost, wish I had done it sooner.

Knowing what I know now, they would be the first thing I would install on any new JT. Worth the money all day long.

Agreed. I had a similar experience with front end issues. Only after replacing most steering components then finally installing Evo correction brackets was my steering corrected. I am running the Mopar lift and if I had to go through this again, I would start by checking for any loose or worn components including each nut, joint, linkage and stabilizer. If no obvious problems were found I would then do the following: install MetalCloak Duroflex lower control arms, Evo correction brackets and adjust the caster to 6.5 degrees.

Thanks for the write up on these. I've got a set of the Metal Cloaks I picked up on black friday sale I still haven't gotten around to installing. Maybe this will be the push I need ha

I've debated the best way to do the install as well, thanks for your tips on that.

Sorry, one more question.... you mention you had the Mopar lower arms, did you keep those or did you go back to stock LCA's with the brackets? I've got both in the garage, but have been told using the longer arms with the brackets is a no no and can lead to too much caster. Thanks!

I'm running Mojave springs with 2.5" spacers on the front and have all the issues you describe, know these brackets will solve them all.

Just use the stock LCAs with the geo brackets. You'll end up with too much caster with extended mopar lift LCAs and geo brackets. I tried all 3 combos (extended LCAs only, extended LCAs and geo brackets, stock LCAs and geo brackets)

Perfect, thanks

I kept the Mopar LCAs, no issue that I can tell, no actual numbers but IMO it does not feel like it has too much caster. It is only .25" longer, I really doubt they make a significant difference.
I also have a Fox TS steering stabilizer I have had on all along. Forgot to list that.

Used the first hole for the upper control arms.

First hole at the top or first hole at the bottom?

I ran them on a JKU with 3.25" lift and stock LCA's. It helped the handling for sure, but it is a band-aid solution in my opinion, but on the other hand, economic.

Not enough to worry about. Still won't be the lowest part on the jeep.

nah it’s not a bandaid.

Low stuff under the axle tubes is never a good idea on something that will be wheeled where clearance matters.

For the street or easy wheeling, no big deal.
