I already have the 1350 front DS already, so I'll probably go with that for now. Isn't it longer as well as stronger? It's a confusing world when the mfr says one thing, and others say something else.
2) The reason for this kit is that all the stock bolts are threaded the lenght of the bolt. They do not have a shoulder. Over time they rub in & out on the mounting brackets and sleeves causeing problems.
I ordered a kit form Q, but they are back-ordered.
3) You can leave the rear for now. I know people with a 4" lift and been running the rear for 4 yrs now. But sooner or latter the rear will go out.
I may get the 1310 when I get the rear DS.
5) Adding a front bumper will not affect handling.
Even a 160lb one + a winch?
6) If you can lower the carrier so you can see better and you like the bumper, get it. But keep looking you might find others you like.
Yeah, I see new stuff all the time, but keep coming back to the Garvin.
7) I Never did put them on any of my jeeps. Just couldn't see why.
I smoke cigars. You can do that when it's raining with those things. Also, if it's 102 degrees and you have to park in the sun (or outside overnight), you can crack the windows a full inch or more and not worry about it raining inside.
8) If you are going to run ARB locker later, sure. But if you just want to fill your tires after you air down there are others out there. I saw on that gives you lines, tank and compressor or you can just get the Power Tank.
I eventually really want on-board air-exclusively for tires. Maybe they did something wrong, but I had it on my last vehicle, and after wheeling, I was often filling up the tires of people with Powertanks that ran out. Probably user error, but the on-board system allows you to have continuous air forever.

AEV 10305050AA - AEV Front MILSPEC Bumper in Black for 07-12 Jeep® Wrangler & Wrangler Unlimited JK - Quadratec

Body / Exterior - Shop By Category
Yes, AEV quit making the Milspec once they started making the MW3 bumper. I got mine just in time. Quadratec had some, but it looks like they're out, too. I saw a new one pop up on Ebay recently. That said, the Premium is the same as the Milspec - just have to 'deal' with crush cans plus you get holes for the factory lights, which many people want. Worst case, you can also cut of the crush cans if you don't want them.

PowerTank website

I've used both on-board air and Power Tanks. On my TJ I had a kitted out Kilby system that used two tanks under the rig above the frame rails and the roll cage as the air tanks. I also had air ports coming off the front and rear bumpers and an interior pressure gauge - sweet setup. But, I still like the Power Tank better. You can get them refilled at any welding supply shop. Most people only use on-board air to air up tires and there is nothing faster than C02.

clvnmcd Sure, meant that my Rock hard bumper lowered the front about a half inch, but the front of the vehicle was a still about a quarter inch of higher than the rear of the vehicle.

Thanks clvnmcd, can you clarify as to what the front was "about a quarter higher" than? Does this mean that the RH bumper with winch is 1/2 inch lower than lifted, but 1/4" igher than stock? Sorry if I'm not getting something obvious. Happy Friday!

Personally, I didn't want crush cans, but didn't want the airbag going off if I dropped off a rock and nailed the bumper either. According to AEV, the crush cans prevent the airbags from going off at less than 6mph. That's Chrysler's threshold, apparently. Worth noting is that the AEV bumper is the only winch bumper that has ever passed Chrysler's airbag tests and, thus, the only winch bumper that has ever come from the factory on a Jeep (i.e. - MW3 edition). That said, according to AEV, it would take a direct hit on end of the frame rail to set off the airbag. So, I opted for no crush cans and mounted jate rings instead. I love the bumper - wouldn't trade for any other one.

Thanks. I like the AEV stuff. Still trying to figure out for sure what to get. It appears that the AEV Milspec bumper is no longer available:

On-board air: I'm partial to 10 or 15 lb PowerTanks. For nearly all recreational 4-wheelers, it more than meets the need: faster air-ups than compressors, portable, and not-complicated. The downside - when you're out of air, you're out of air. But, in 17 years of wheeling, the only time I've ever seen that happen was when we were fixing a blown ring and pinion trailside and using the PowerTank to run the air tools.

That sounds fun!

I knew this before I typed it, but was kidding myself hoping people would forgive the length and see that I was trying to avoid creating nine new threads, which would lead to too much chaos, as there are probably 150 new threads per day. That's why I said "I would greatly appreciate any good advice on any or all of the questions below." But I should have known that my lengthy list of disparate questions was too combersone. Anyway, I appreciate you taking the time to sort through it. I hope I can help you someday.

That said, I'll take a crack at some of these and see if it gets a few more responses going.

I do not believe it will affect the ride other than by smoothing out any potential driveline vibration you're getting now due to your lift. It will be a good thing.

Thanks. I will have it on early next week and will report to anyone who cares.

I can't imagine why these would be bad, presuming proper installation.

I ordered them, but they are sparse, and on back-order for a while, who knows how long.

This I do not know. Your rear shaft is longer, so the geometry isn't as sharply affected by your lift as your front. If you don't replace it, keep your eye on the ends for any sign of leaking. Pay attention to undue vibration as well.

Thanks. I was hoping kbwwolf would chime in, because I think he has the answer, but sadly is being quiet, possibly because I offended him with my ignorance or something else.

You got it right on the airbags. It's the crush cans. I don't believe it really makes much practical difference. Many jeeps have aftermarket bumpers and there isn't a widespread airbag problem. I've never seen any tests that actually determine the precise speeds, etc.

It'll make the nose of the jeep that much heavier while wheeling and for hard breaking. And don't forget a winch is going to add another 60 to 100 pounds. For me, Rockhards are just too heavy. Are folks really finding 3/16" steel too weak?? Not that I'm aware of. What exactly are you planning on ramming into? But that's just my opinion--Rockhard sells plenty of bumpers.

You're probably right. It's just that seven years ago, I had a car pull out in front of me while I was going about 65 mph in my '03 Sierra with a really strong steel bull bumper and I hit her at about 40-45 mph after braking. Fortunately, no one was hurt, but her car was crushed, and my truck was made perfect with about $150 worth of welding. I just wonder if the Rock Hards were worth something in that respect.

I know it's a balance between that and the weight issues, I just didn't know where to come out on that.

That's my 2 cents.
Happy New Year MTH and thanks for the help.

Questions re. 2012 JKUR Modified Suspension, Drive Train, Bumpers, Gadgets, etc ...

For context, here’s what I have:



2012 JKUR with 4” Pro Comp Stage-II lift with MX-6 shocks, 17”X9” wheels with 4.5” BS, aftermarket steering stabilizer, and Smittybilt side rails.

Like most people, I drive most of the time on pavement, but I only bought the Rubicon because I want to keep wheeling off-road in challenging environments, like I have done most of my adult life.

I would greatly appreciate any good advice on any or all of the questions below.

Here’s what I’m doing next for sure: putting in a JE Reel 1350 front DS, based on kbwwolf’s helpful advice. http://reeldriveline.com/catalog/front-1350-heavy-duty-drive-line-jeep-wrangler-2012-24door-auto-trans-p-30.html

Question-1: Will the installation of the front DS just make the system stronger (by being stronger itself and improving geometry), or will it affect the way it rides somehow? I like the way my Jeep rides right now, even though it rides a little more like a truck than it did when stock. It is a truck of sorts.

Next thing I might do: Install the Synergy Suspension Jeep JK F911 Hardware Kit: http://www.quadratec.com/products/16315_6510.htm

Question-2: Is that necessarily a good thing? I can’t tell. I read “yes,” and I read “no,” and can’t figure out who’s correct. Are there any downsides to doing it other than losing $65? If not, that might be the answer.

Question-3: Should I replace my rear DS? I get the impression that it improves the geometry, but not as much (and thus is not as critical) as replacing the front DS. Is that about right? Or is the value in replacing the rear DS not about geometry, but rather about the strength of the DS itself?

I want a bumper mounted winch, and prefer to have a real steel “truck bumper,” unlike stock. There are three front bumpers that seem appeal most to me:

1) Rock Hard 4x4 Parts Full Width Front Bumper:
http://www.quadratec.com/products/12065_1004.htm

2) ARB: http://www.quadratec.com/products/12000_1202_07.htm

and

3) AEV: http://www.quadratec.com/products/12049_1201_07.htm

Question-4: Is it mostly personal choice between these or other similar ones? I know the latter two are “air bag compatible,” but what does that really mean? I assume it means it retains the stock system that helps avoid air-bag deployment at lower speeds, but, in practical terms, I don’t know how big of a deal that is or at what speed-ranges that comes into effect.

Most typical aftermarket front Jeep bumpers seem to weigh about 100-115 lbs. The Rock Hard bumper weighs in at a whopping 160 lbs. I like the fact that it is made of 1/4” (rather than 3/16”) steel, as it undoubtedly is stronger, but:

Question-5: With a correctly-lifted Jeep suspension, will the extra 50-60lbs on the front end come with any significant downsides? I know it will require the engine to consume a bit more fuel, but will it negatively affect, materially, the handling or stability? Note that I weigh about 200lbs, and when I sit on my stock front bumper, it barely drops (maybe at most 1/2 inch).

Since I now have 35s, I apparently need to get a spare tire mount/carrier. I have looked at a lot of options, and kekep waiver on some, but I keep coming back to the Garvin rear bumper: http://www.quadratec.com/products/12042_6100.htm
It is adjustable to allow you to mount the spare as low as it will fit (lowering center of gravity and allowing me actually to see out my rear window), it can come with gas can holders and a rack. Several others look good as well and do much of the same, but they have something I don’t like. For example the Rock Hard one is not adjustable, and puts the spare up in the sky: http://www.quadratec.com/products/12066_903.htm

Question-6: Am I going wrong if I get the Garvin, and/or am I overlooking some other equally-good or better choices that meet my needs?

Question-7: Anyone install a window deflector, like:
Wade Automotive Products 51465 - Wade Automotive In-Channel Wind Deflectors for 07-12 Jeep® Wrangler & Wrangler Unlimited JK - Quadratec ??
I had them on my last vehicle, and liked that I could crack the windows and not worry about rain intrusion. But I don’t know how they fit/work with the JK.

I would like on-board air, as I used it all the time in my previous vehicle.

Question-8: What is a good choice? Something like this?: http://store.arbusa.com/ARB-On-Board-High-Performance-12-Volt-Air-Compressor-CKMA12-P3572C9.aspx
Something else?

Thanks in advance for any good info/advice.
