Jk lift 3" or 4"
 
I am doing some research on the lifting a JK but i had some questions.

I was thinking of putting 35" tires on a rubi and it seems a 3" lift would be adequate.

Here are the items i found that are needed:
3" coils,
bump stop extensions,
longer shocks,
rear brake line extension brackets,
longer rear sway bar links (factory links can be installed up front),
adjustable front track bar

rear track bar relocation bracket
adjustable rear upper control arms
adjustable front upper and lower control arms
new double cardin U-joint style drive shaft
regearing to 5.13

However the cost to do a 4" lift compared to a 3" lift really seemed minimal just couple of extra items.

So my question is this will a 4" lift on 35" tires 17" work and drive fine and not look gay?

Also a 4" lift will run 37" tires (that just seems huge too me) is it a big difference, are 37's the way to go?

Also this will be a DD, but only about 40 miles round trip.

Also what about wind, there is bad cross wind twice a year about a week or so at a time where i live. Is this a concern i need to be aware of with 37's or 35's?

The reason i am asking is it is quite an investment to put on a good 3" lift so is it worth the extra cost to just make it 4" with the option of putting 37"

Hopefully that makes sense. I am still a noob in the jeep modding arena. Also am i missing anything else to do the lift.

Thanks for the help

I'm looking at Rockfather by OME, not too expensive and claims rides better than stock. So far the scuttle butt out there is that the OME is a good lift. My purchase window is late spring early summer. So far I'm zeroed in on the Rockfather. Could have my mind changed by the time purchase time comes around.

i read an article on the nth degree/ AEV 3.5 and 4.5 lifts and actually tested with 35 MTR's drove better than stock on a solemn course but they arent cheap, basic being $1300

This is one of the reasons I have been eyeballing the Rockfather, approximately $1000.00 complete. With the extended shocks. I'll most likely get the rock protectors for the diffs too.

I have the Rockfather lift with 35's.
I love it.

yj-genral 10-21-2009 03:06 PM

cant you fit 37's on a 3" lift with the JK? just need to limit uptravel a bit more so you dont scrub, i would think...

<---dont know

I also have the rockfather lift & mine rides nice, I am a happy camper. Here is an article on it :
Jeep JK Wrangler, Rubicon, Unlimited 4.5" Lift kit
featuring Old Man Emu components.
As seen in 4WD & Sport Utility Magazine

Crappy springs are the bane of the Jeep 4x4 world..... prevalent, horrible, tough to identify. Advertising budgets and flashy colors in pictures make great camoflage for them. They'll take your dream toy and turn it into something no one wants to ride in, and you curse every day you failed to research properly and wound up on those stiff big brand name springs.
Spring manufacture is a fine art which very few companies take the time to engineer properly. The largest names in the business are guilty of it.... mass producing cheap springs that ride brutally stiff, but sell well because of the insane markup that most 4x4 shops get on those springs.... meaning they really push those big name kits. As a general rule, the less markup on a spring there is, the less likely you are to see it on your local 4x4 shop's shelves.... which is why you rarely see Old Man Emu components. They are the best quality parts, but not the most heavily advetised. At Rocky Road... we look beyond hype and really do take a different approach to our customer's Jeeps. A better one...

There is no question about it, the world knows that Old Man Emu springs cannot beat for ride quality. The only complaint we ever see on them is that they are not too tall which poses a problem for folks looking to run taller tires, but who still want to enjoy their daily ride in their nice Jeep. OME avoids the more 'extreme' scene by manufacturing mild lift springs. Old Man Emu may not be the most well-known to 4wheelers, but in our industry they are undisputably the best.

At Rocky Road, we do like to push things a bit taller and so have developed a 4.5" system with the Old Man Emu springs for your JK. We have combined the OME springs with additional components to offer a fully properly engineered suspension system that not only rides far better than anything else on the market, but can handle up to 36" tires. You got it... a full 4.5" suspension featuring Old Man Emu springs. With some fender trimming or a small body lift, you can go even taller on your tires.

Almost as bad as those poor quality springs nowadays are some of the "long arm" kits that are on the market. Many of these kits do not allow your front axle to cycle up and down in the manner it was designed for which is why they handle so spooky at highway speeds. Long-arm kits are cheap to make, very profitable for sellers, yet can be scary at highway speeds. Those systems are fine for vehicles trailered to the trails. The the rotating castor on these systems is what makes for the spooky handling... picture your Jeep turning like a skateboard. They do look super cool in a picture in a magazine, but most of us need to have reliable and safe transportation daily, which means skipping long arm kits. Even magazine tech editors agree as noted in numerous articles on the subject. Your life is worth more than 1-2" of extra flex on the trail.

Picture shows OME springs, shocks, rear track bar,
DOT brake line, and our easy bolton diff guard.

An additional and VERY important feature you should note on our lifts is that we have Medium and Heavy Duty kits available for the 2door and the 4door. How many suspension manufacturers do you see with a one-size-fits-all kit? Pretty much all of them. Does it make sense to you that one spring fits every Jeeps's needs? Of course not. Its because they simply didn't want to do the necessary engineering to allow Jeepers to custom tailer a lift to their specific needs.

At Rocky Road, we understand that not everyone runs a winch, or has a full fiberglass hardtop. Some of us go doorless. Some use our Jeeps for towing. We can mix and match the springs as well if you like by calling in your order. Our website shows the most common Medium and Heavy Duty combinations, but we are very happy to customize your suspension for you. Our spring rate selection allows you to make sure you are getting the exact ride you need for your usage. The other suspension manufacturers... apparently think we are all identical.

We also package in soft riding Rocky Road Engineered shocks. Tired of shocks from the 'brand name' suspension companies designed for the weight of a full sized V10 pickup truck? So are we!

Rocky Road soft-ride long travel shocks. We feel we have designed the best riding shock we have found on the market today for moderate weight vehicles like our Jeeps. Other shocks are designed for vehicles thousands of lbs heavier (namely, pickup trucks), our engineered shocks are right on the money for a Jeep. Superbly valved for a great ride on road without being mushy offroad.

OR, the ever-popular Rancho 9000XL Adjustable shocks are available as an upgrade option, which allow you to adjust and dial in your shocks for your favorite setting, or change it up depending on the driving and terrain you hit for the day.

The Trailblazer 4" lift kit is the perfect size for tires up to 36". A great size safe enough to run on a daily driver, not overpowering to braking and steering systems, yet a great size for off-roading on all but the most extreme of bottomless mudpits or rockcrawling competitions.

Handles like a dream at speeds over 80mph. Rides more comfortably than any other suspension we've come across....
Click pic for a larger view.

Each Trailblazer kit includes:

Old Man Emu replacement front and rear coil springs with spacers for a full 4.5" of lift. Simply put, the best riding spring on the market available.

Long Travel shocks. A great soft riding RRO Engineered shock designed for the medium weight of the Wrangler. Rides like a dream onroad as opposed to other STIFF shocks.

Adj Front Track Bar. Anytime you go over 2" in lift, you must replace the front track bar to keep proper front axle alignment and handling.

Adj Rear Track Bar. Anytime you go over 2" in lift, you want to adjust the rear track bar to keep proper rear axle position and handling.

Full DOT Rubber brake lines. Stainless lines fatigue and are prone to bursting.... which is why no vehicle manufacturer EVER uses them. Our brake lines are DOT rubber and state inspector friendly. No red flags raised, 100% safe. All other kits on the market use the cheaply manufactured stainless lines. These top quality rubber DOT brake lines are a Rocky Road exclusive.

Bumpstop extensions keep your whopper tires from hitting on the body.

Rear Bar Pin Eliminators. A common problem you hear about on the JK is the rear shock mounting bar pins. They slip sideways, they make noise, or they may just pop off and unattach from the vehicle altogether. Our BPE kits eliminate this. Again, a unique feature to the Rocky Road fully engineered suspension system.



OPTIONAL UPGRADE: Swaybar disconnect kits front and rear. Swaybars on... your Jeep rides nice and stable on the pavement. Tracks correctly, feels secure. Disconnect the swaybars... you now have a FLEX monster capable of handling even the most challenging trails. Our front AND rear kits make sure you've got the most articulating JK on the trail.

Just so we are clear on this photo....
Rockfather 4.5" lift
36" Mud Terrain tires
handles like a dream at not-so-legal highway speeds
OBSCENE MONSTER SUSPENSION FLEX!!!

Other long-arm kits might flex well, but they can be spooky at speed. With the Rockfather suspension, its all good.

All these components add up to the finest riding suspension on the planet. No hocus pocus parts that are unnecessary. No dangerous long-arm kits. Just the required components to make your Jeep ride more comfortably than stock, be stable on the interstate at 80+mph, and top offroad performance.

More pictures coming soon.

For some good information on why the OME springs offer such a superior ride, please visit our OME springs page at the link below.







One important fact we really do want to convey: Don't think you are not getting the absolute best suspension on the market because our prices are well below our competition. At Rocky Road we believe in providing the best components at the best prices. We don't want to make our competitors cry, but with our unbeatable prices and these top quality components... they just might.

what size is your lift 3" or 4" and could you go with 37's?

jcf 10-21-2009 04:34 PM

It is 4.5" - I am not sure if 37's would rub. The site with the RFL is www.rocky-road.com they are here in Utah & that article I posted was off their site. If you call them ask to speak to a manager as some of the sales guys aren't very helpfull. The Jeep in the jk4dr Rockfather lift section is actually mine before I bought it. They made a mistake saying it has 36" tires, it has 35's

CruserBruiser 10-21-2009 06:33 PM

I ll tell you this, if you go with the 3" lift you'll be wishing you had the 4" lift.. I have a 4" Pro Comp lift with 35's on 17" wheels and i think its perfectly proportional. The ride is just as good if not better than stock. cross wind is nothing to worry about cause its not gonna flip you over or anything, unless you drive through a tornado everyday. As far as the 37's are concerned I think they would be to big for a 4" lift.

WhiteRAVE 10-22-2009 02:30 PM

Ok i was only thinking of getting 35's anyway, but if for some reason 37's fix are they worth it?

I have been reading other forums about the EMU, they seem to be very good, do i need controller arms with the lift? Do you use them or something else?

I'm in the same boat with you thinking of an OME lift for this coming summer. I plan on getting the Rockfather kit. They say it contains all items needed for the lift. With the advice I have gotten by reading posts to exhaustion, I am going to install the kit, and try it out. Then see what else is needed beyond that. I plan on getting some protection for the differentials when I get the kit because with that much lift, they become one of the low flying vulnerabilities that begs for protection. I'm sure there are other vulnerabilities that will need looking into but that seems the most expensive one and exposed one if damaged.

WhiteRAVE 10-22-2009 02:44 PM

ya i think that is a good idea, i don't like the idea of spending money unless i have to.

however, I am worried about the drive shafts i was reading another forum and they talked about the lift may cause a lot of strain. I definitely don't want to break it.

they said i would need a double cardin U-joint shaft. So i may look into that.

Just Empty Every Pocket

iamagolfspaz 10-22-2009 03:53 PM

Look into adding about another $1000.00 for new drive shafts. That's if you can install them yourself.

The folks who sell the lift do not recommend going with new drive shafts. I'm going to go with that. If the drive shafts that came with the jeep are not up to the job, it won't take long to know that. I don't think that is the case. Worrying about getting the shaft on the shaft is something that is done based on anecdotal about shafts breaking not people's worries.

I have Pro-Comp 4" lift with 37's. Added 1" body lift and no rubbing.

iamagolfspaz 10-22-2009 09:04 PM

Waiting to hear more about 4 inch's of lift, 35-37 inch tire's and stock drive shaft length. Would love to hear from someone that had their shaft break while somewhere out in the middle of nowhere. Especially with an automatic.

I had my transfer case linkage break out in the middle of nowhere. A 60 cent plastic bushing. TC was stuck in neutral. I now have three bushings in the glove-box because a bushing in the glove box is better than two in the bush??

did you change your drive shaft or make any other mods to put on those 37's, other than your lift?
