Short arm geometry question

Hey guys... I've had good luck with this forum, and know you guys will give me a straight answer. I've been collecting parts for a 6" lift for awhile and have enough parts to put it on. I'm going short arm for now, with drop brackets in the near future. The problem is, with the adjustable uppers and lowers adjusted to the lengths specified in the chart that is floating around, the geometry is WAY off, with caster at like 10 degrees positive and the springs are hitting the upper bumpstops. I'm NOT looking for specific numbers, just tips to help me figure out how to adjust the arms correctly and correct the geometry. My google searches have only turned up the table of lengths and a few unrelated articles. Thanks for the help!!!

I used the same tables they suck. I left the lower arms where they said to put them and pushed the upper arms out an extra inch. Worked out perfectly. Stay as far away as you possibly can from the lower control arm drop brackets. They are a joke. Just another hackerish item on the market. They put way to much stress on the frame mounts and can rip them off and hurt ground clearance. 6" on short arm is fine. Leave it alone.

im sitting at 6" in the front now on adj short arms, and yes, it creates an angle that does not contribute to a nice ride. but it does "work".

actually the drop brackets are great. according to someone who actually has them they don't ever get hit and they ride phenomenally better than a short arm lift in the stock locations. and they don't 'rip off' if you install and brace them correctly.

Drop brackets = Cheap way out. I would never use them. If your worried about your angles spend the $ buy a long arm kit and do it right. Your only lifted 3" you could run stock control arms for that. Drop brackets at 3" will do more harm than good.

Thanks for the input guys! I'll try extending the uppers a bit and see what happens. I would have loved to go longarm but my wallet is about empty right now. I know the ride will be a bit harsh but will be fixed with the drop brackets. I just need to get 'er back on the road for now. Thanks!!!

I find it funny you are telling the OP short arms on 6" of lift is fine, yet dropping coin on drop brackets is a cheap way out. I agree it's a cheap band-aid to a problem that could be fixed with long arms, but don't contradict yourself.

6.5" of lift on properly adjusted short arm is fine. You dont need drop brackets. It's a cheap way to to gain a little flex yet sacrifice ground clearance. Not to mention they look terrible. You wana run em go ahead. Id put my jeep in the garage and park it till i can afford long arm before i hack it up. Its amazing. Everyone wants to build there trucks yet no one wants to pay for it? Maybe you need a new hobby. Do it right or dont do it at all. If you cant afford to do what you want, join the club. Buy 1 part at a time. When you have it all. put your lift in!

The drop brackets are fine and lots of people use them with great success, can you post some pics where they caused the frame mounts to rip off your jeep?

some of the worst advice I have ever heard. The RE drop brackets are a good set-up. Sounds like your 6" "lift"with stock locations is a joke to me, wonder how much stress is put on your mounts with those heinous control arm angles. They are made from .250" plate, you are not going to hurt them by dragging them, you do lose some ground clearance but MUCH better than driving around in a death trap

Properly set up drop brackets with bracing are just as strong as the stock CA mounts, if not stronger. Gaining flex is not the issue here, it's dealing with the piss poor ride quality you are going to get with short arms on 6" of lift. And you talk all this talk about how it completely robs ground clearance and that long arms are a much better alternative. Go look at the clearance from a rig on drop brackets, and compare that to a rig on long arms and they are almost the exact same.

You keep telling the OP not to cheap out and do it right, yet 6" of lift on short arms is perfectly fine. If you are going to play the do it right or not at all card, maybe you should tell the OP to put the wrench down, and leave his rig at the height it is until he can afford long arms. Don't play both sides of the arguement.

To the OP...I'd keep on saving for Drop Brackets or LAs. You've waited this long, you might as well do it right.

Check the classified sections from time to time, sometimes the drop brackets get sold that way.

I am at 6.5" of lift with short arms and I'll tell you this, I wish I would've done a little research and spent my coin the right way, on a set of long arms.
