I couldn't agree more. Drives me crazy seeing rigs on the trail with big tires and lifts without any protection or recovery capabilities.

I'm saving for a metal cloak 2.5" Dual rate ARB edition and will also put tires on at that point.

For now, I've done bumpers, winch, rock rails and diff gliders will be here in 2 days. I may not be the biggest jeep out there, but she is armored up.

If your gonna go with a lift kit, then do as planman has stated, get a kit that gives you every thing you need. Yea, my kit will run $1,600, but why spend $500 and have to keep adding.

Rear lower coil degree correction wedges
Rear lower coil retainers
Springs that net 3.5" in the front and less than 3.5" in the rear on a 2 dr (usually net 1" less on a 4 dr)
Longer rear swaybar links
Longer front swaybar links or swaybar quick disconnect links

A 3.5" lift that doesn't include these things at a minimum is insufficient.
I agree completely but have a question about the coil degree correction wedges. they came in my kit but my installer didn't use them. Are they necessary?

Not required for a 4 dr with a stock rear driveshaft.

Your rear springs will bow back a little and run softer due to the bow.

They are a bigger need for a 2 dr at that height, especially if you run an aftermarket driveshaft and run rear upper adjustable control arms.

i get it now, in case you clock the axle back to correct pinion angle, it would cause the rear springs to bow to the rear

Yes. However, the axle clocks back automatically with a lift of any kind due to the arc of travel from the control arms staying fixed while the distance between the frame and the axle increases.

Would adjustable control arms fix this?

Yes I agree,

Going big and high is not cheap. Doing it the cheap way may lead to a lot of troubles. So if you want to be a man and play with big boys, do it right or just don't do it.

I see a lot of JK with 37'' and basic 3.5-4'' lift while the rest remains stock. Those are the first to ask about death wobble and vibration or any other issues related to a poor build...

We all want instant gratification, but a what cost? Sure, your $500 lift looks good, but what components are suffering due to the incomplete lift... The trails aren't going anywhere. In the meantime, stick with blues or single blacks...

The fix is rotating the rear lower coil perches or installing rear lower coil wedges and coil retainers.

That's why budget builders should stay at 2.5" max. With flat flares and correct bumpstops, they can run 37s. They don't need adjustable trackbars or control arms. They can prioritize funds to regearing and chromoly axle shafts, etc.

To lift a rig 4" correctly is a $2k-$3k cost, plus driveshafts.
