Is that hard and fast rule or can I pull it off on 3.5" without negative effect (caster, maybe). And would a good alignment shop be able to get it right.
I'm not opposed to new coils (Metalcloak 4.5" progressive for instance) but if I can get away without..

Thanks
The issue you will have is the angle of the control arms. The point of the CAD brackets is to put the LCA at the stock angle for better articulation and ride. The LCAs should be parallel with the ground for best ride. At 3.5” they will be angled up. Not sure how that will act.

I can tell you I have CAD brackets on mine at 5” of lift and it rides great. Does decent off-road for what I do.

If you play on rocks you'll be dragging them like boat anchors.

At 3.5" itl be like a 1/2" lift after installing control arm drop brackets. Arms will be virtually at factory angles.

lower the lift the better. I dont think id do drop brackets with 2" of lift. Or 5" inch.

On 5" id be doing all kinds welding and cussing. Raise arms at the axle side and lower frame side..

3-4" is perfect for drop brackets.



I haven't yet been hung up on lower arms. Though bottom side of both arms are no wearing pretty heavy rock rash. I dont see control arm drop brackets getting hung up any worse than what mine dont. Lol

If you played on the rocks like I do they would be bashed up very well. My factory lower brackets on the body side have the front corners flared out from landing on rocks and dragging up ledges. I am going to a 3 link soon at 4" and have little worries about the arms vs the factory sheet metal brackets.

Really liked this write up. Definitely wanna do a LOW COG, but being as mine is also my DD and I'm currently on 33x12.5x15 at stock height with lil bit of trimming on the rear with 1.5 in spacers with stock Dana 30 and chrys 8.25 axels. I don't rock crawl in her she does see a lot of mud like a ridiculously huge amount of it but also alot of asphalt throughout the day. My question is what's the bare minimum I can do to keep it low like it is (or within 2.5 inches I reckon) and still be able to go from having her buried up to her radiator in the mud to hitting the street right afterwards I mean she does fine as she is I just feel like she could use more. And don't judge me on that breather tube lol old one busted and my brother threw that together so we could go muddin that day lol.

I'm on an IRO 5.5" 3 link and the rear has very little up travel. Ideally I'd like a little more to be fully comfy onroad. I overestimated my bump stops thinking I might even try 37"s but found a good deal on 35"s and still have a mostly stock driveline. (front Ox, rear powertrax no-slip, H 'n' T, with stock front driveshafts both front and rear) It really really depends what sacrifices you want to make. My next step is tube fenders and rockers so I can get my hooligan boatsides on. I think I might "re-tub" the rear but i want to keep all the interior space I can. (Need to save room for 3 under 4, wife and dog along with the tools, winch, trail spares, etc &#128514

I have a few videos between the 35s and two from the 37s. I'm going out again on the 28th so i'll see if i can get more videos. I'm learning where these tires like to play, 8psi was too much on the rocks.

How do you like those tires? I have cheap Ironmans that came with the wheels but i've been curious how those Razr's work, seem like the creepy crawlers are hit or miss.

Tires work well. I run about 15psi all around street trail driving. I dont do a ton of Rock crawling tires do very well on dirt and soft soil n mud.
I did manage to rip a sidewall out with maybe only 200 miles on tires. Put the bad tire on the rear and pressed on. I now pack a big Patch glue and means to dissmount and reset bead on the trail.

Pretty impressed this wheel survived. Ran it for 2-3 miles with no air then another 2-3 as pictured. This last climb took out a front 30 shaft then she was dead. Winching this last few hundred yds to where my pickup could get to. This climb seemed like 10 miles of dragging cable. Looking forward to your vids and pics

That's good to hear. I've liked the look and idea of them since they came out.

Great read, wish i would have saw last year when i built my 3 link, would have saved lots of late nights. Here a few pics, any questions i can answer, built all of it, bought very few pre made parts... id rather build than buy.
