AEV 2" Spacer Lift

[jeepers29]

Not impressed with Black Bear. It’s a simple trail. I did Cliff Hangar in Moab in the dark because someone broke down on the way out.

I have nothing to prove.

They are all simple in Ouray, once you get past the shelf roads and drop offs. We go they for the views.

I'm confused... polyurethane is just a denser/stiffer "rubber". This should be a non issue. Instead, it would come down to something loose, or not seated properly.

Now, if u have poly-ethylene/styrene or any other plastic based poly-, then I can understand the possible issue at hand.

That said, I have RC metal spacer lift, as bad or worse than using plastic, and don't have any rattle. I know it's not the same as AEV kit, but shares in similarities with using anything other than rubber for isolation, if ur kit has plastic spacers.

I’m not a chemical engineer but plastic and rubber are different.

I’ll agree that poly spacers are plastic. It has nothing to do with your rattle. Did you torque the rear control arms correctly or not?

If I had a Rubicon I’d do a suspension lift over a spacer lift anyway.

Interesting, I've always known polyurethane to be more rubber related due to its flex, feel, and how the automotive industry has used it (bushings).

I will agree that rubber would be the better solution, as well as cheaper. But polyurethane in most cases, pending durometer, is a more than viable replacement, pending on performance/application needs.

Thank You! So far you are the only one who gets it.

You’re in denial. Is a full quality suspension system better than a spacer lift? Sure. That’s not what your initial post was about. You’re claiming there is a problem with a specific lift product, but your claim is unjustified. It’s not fair to AEV for this not to be challenged. I don’t have any connection to AEV, but they take the time to make sure their stuff works well. Best of luck with your new suspension system. Just make sure to torque everything correctly…

Don't make it personal. You have no idea how I think.

I have no problem with AEV. They make lots of great stuff. Their spacer lift is simply a low budget alternative to lifting your Gladiator 2-inches. Sounds like lots of people here took advantage of that savings.

However, that does not mean that the AEV 2-inch lift is the best lift they offer or that there were no compromises made to get the price down to $449. Creating a polyurethane spacer that also replaces the factory rubber isolator kept the cost down but it wasn't done because it's superior to a rubber isolator.

AEV doesn't make control arms because they are very aware how the durometer of the rubber Mopar users is key to the way the suspension works. You can take a factory Jeep with the shocks removed and drive it over a bumpy test track and the body remains level. That's how much the rubber bushings and spring rates matter to the engineering of the ride. So when you pull off a rubber isolator it matters. How much? Probably not nearly as much as suspension bushings but it's no accident the factory isolators are made out of rubber.

If I was into overlanding I would probably choose the AEV Dual Sport lift. Unlike Mopar they use progressive rate springs and their shocks are tuned to those springs. As a result get a firmer more controlled ride than stock. You can also carry more cargo without the rear squatting nearly as much.

But I am not into overlanding. I like my Gladiator pretty much as is. I just wanted to make sure I didn't hit high center on the trails. The best solution for me is to install the Mopar 2-inch lift which achieves the following:
1. Improved suspension sound deadening.
2. Preserves stock ride quality.
3. Increases the amount of articulation.
4. Maintains optimal front pinion angle.

Probably should have put something at the end of your initial post saying are not open to what other people have experienced with the AEV spacer lift or other opinions of what the noise may be.

Boo hoo. Everyone is allowed to have an opinion. We all don't have to conform to the herd.

I'll agree that the Mopar 2" lift will increase your articulation over stock. Sound deadening realistically isn't going to be any different vs. stock, and I doubt it will be different vs. the AEV (based on my experience). The ride quality will be a little stiffer with the Mopar lift with the Fox Performance shocks, but most people do like them better than stock Rubicon shocks. When you say that it "maintains optimal front pinion angle", are you referring to caster angle? Because pinion angle isn't necessarily the 1st (or even the 2nd) concern when considering front control arm lengths (with a CV driveshaft).

I drive my rubicon every day, we drive on farm roads, back roads, gravel roads, farm fields tractor roads and any other terrible road. I have the 2” AEV lift and ZERO NOISE. Sometnings up if you have noise. I did install mopar lift lower control arms.

The Mopar arms are an excellent add-on to the AEV 2” lift.
