Ill be getting this kit soon & have some questions.
1) it appears the control arm brackets attach on top of the crossmember? If this is true then the crossmember will now hang even lower
2) I'm contemplating getting the HD crossmember since it sits 2" higher and I'm hoping running it with the IRO kit.
3) IRO claims hd crossmember won't work with stock exhaust- BUT since I'm installing it with the IRO kit it should fit with stock exhaust since the control arm brackets will lower it some as well.
4) do I have to remove the coils for install? I'd rather not use the provided cylinder coil retainers but instead use the lower retainers IRO sells
Thanks Guys! Photos provided

You misread, it works fine with stock exhaust.

1: yes by 1/4" the pic you posted has a TC drop kit installed.. dont use it!
2: is that a question? i say get it
3: exhaust should be fine
4: the retainers are for holding the spring in place when articulating. you dont have to remove the spring for install.

I can take pics later of anything you want, just let me know!

Excellent! I enjoy being wrong on this stuff, as long as it works fine with this kit then awesome news I don't want my crossmember hanging so darn low

Awesome man thanks again, hopefully ill get it ordered by Monday and possibly so work next Sunday how long did it take you i will have a second hand when doing this. Can't wait to get it the highway speeds and around town are killing me on short arms at 4" up front, terrible alignment with caster and so bouncy around town. Just need it to be smooth

Also at 4" up front do I even need the adjustable arms? I'm hoping the fixed ones with the caster adjustment will be enough to dial in alignment ect. Thanks

install took about 7 hours with a post lift and all the power tools I could think of you should be fine with non-adjustable arms. the adjustable ones allow you to move the axle forward or back

I'm doing just the front arms and brackets hopefully I can knock it out in less time but then again there's always the learning curve where one side takes longer

Had taken me about 4 hours dealing a cheap drill bit and an underpowered drill.

FYI, don't lose the tapped inserts inside the frame rails, not fun trying to get it back.

Ok good 7/16 drill bit check! Please elaborate on the tape on frame rails?? Also I'm reading the instructions on 1/2-2.0 thread hand tape what's the all about? Thanks again I'm sure we will nail it
Also after reading instructions second time through it sounds like 13) bracket install inserting the nuts through the hole in frame rails is going to be a Beatrice how much room is there to deal with down there lining up the bolt and nuts & how do you torque them down with nuts being in frame rail? Can you fit a wrench in there? Thanks guys

the hand tap is for tapping the upper perch to install the long tube spring retainers.



there are no nuts for the frame rail. it's actually a threaded plate. each plate has 2 holes. they are inserted into the rail and then the bolts screw into them.

watch this video for more info

What you referring to as "nuts" is what I'm talking about, they are a rectangular pieace of metal that have threaded holes on each end. The first one I pushed in the hole slide down past the cross member bolt holes.

The flanges that you mount between the cross member and frame is about a 1/4" thick so it will drop it down just a hair.
