Currie / RockJock CurrectLync with 4.75" lift - drop pitman arm?

[infiniteDH]

Recently upgraded to 35s and tested them out at the Greenbrier Jeep Jamboree a couple of weeks ago. I'd been planning to upgrade my steering linkage to a Currie CurrectLync but hadn't gotten to it yet. Well, during some rock crawling fun, I bent my stock tie rod. (At least it's smiling and not frowning!)

I was about to pull the trigger on the CurrectLync at Quadratec (RockJock CE-9701 CURRECTLYNC Heavy-Duty Tie Rod System for 84-06 Jeep) and read that more than 4" of lift requires a 2" drop pitman arm.

I have a 3.5" Rubicon Express suspension lift and recently added a 1.25" body lift when I added my Atlas and my belly up skid. With 4.75" of lift, do I really need a 2" drop pitman arm? If so, what issues might that mod introduce? If I don't swap out the pitman arm, what risks does that introduce with the CurrectLync? Thanks!

TL; DR: With 4.75" of lift, do I really need a 2" drop pitman arm for the Currie CurrectLync? Why or why not?

Drop pitman arm is not needed !

If you have a dropped track bar bracket that also needs to be removed.

Body lift has no impact on suspension lift calculation. Do not install a drop pitman arm unless you want bump steer.

Wouldn't it be better to explain that the body lift doesn't affect the steering relationships? Even if he had a 10" body lift, he still only has 3.75" of actual lift that matters when it comes to the steering and suspension.

Body lift has no impact on suspension lift calculation. Do not install a drop pitman arm without the matching dropped track bar mount unless you want bump steer.

FIFY

You don't add body lift when talking about suspension. They have nothing to do with each other

You want the track bar and drag link to be close to parallel (like the stock set up). If you move the attachment of either end of either of those you will lose the parallel configuration and get bump steer. So leave them stock. Also, your body lift has no effect whatsoever on your track bar and steering linkage.

I was in the last minute of my morning shit. I figured let him know the basics and you guys will take over with the rest.

That's how I do it when I don't know what I'm doing.

Thanks everyone. I should have known that body lift didn't go into the calculation. Appreciate no one outright calling me an idiot.

We just didn't do it where you could hear it.
