6 inch skyjacker?
 
I have an 04 6cyl 5speed wrangler. I previously had a pro comp 4 inch lift but now im looking into the skyjacker 6 inch rock ready. I can't find much info on this kit, does anyone have any advice? it will see very light offroad use and probably run 35's. Will this kit ride good on the road?

how much can i expect to pay for install from a reputable shop? can i do it myself? any welding? how hard is the slip yolk and ds install?

thanks

How much is this kit? If it's north of $ 2k then there are much much better suspensions out there.

It is around $2500. If someone could steer me towards a better lift i'd appreciate it. Again i wont be doing much offroading but i dont want to buy low quality junk. Better ride on the road would be more important. also something complete would be nice, a steering stabilizer, etc.

is there different options for SYE and driveshaft? whats better?

Why is the kit so cheap? Even adding the SYE and driveshaft its only ~$1600

I was under the impression that if it wasn't a long arm kit the stability would be compromised

if your going to spend 2500 on a suspension go with clayton.

It is a short arm lift, and I can't recommend it based on that. You will need a long arm kit to get good drivability. Check out RE w/o the upgraded tri-link rear would probably suit your needs or Rock Krawler are the best from what Ive heard.

^ X2 --- Or go with a Rock Krawler 5.5" or Rubicon Express 4.5".

$2500 for a 6" short-arm kit from Skyjacker would be a poor choice in my opinion. First, it's my opinion that Skyjacker is a second-tier player in the Jeep suspension lift game, with ProComp being right there with them on that same second-tier list. Second, it's going to ride like crap... the uber-steep control arm angles from the short control arms will make it ride much more roughly, which is why suspension lift manufacturers started coming out with long-arm suspensions for tall lifts.

Long control arms are not nearly as steep as short control arms are at the same lift height. And the steeper they are, the more shock the arms transmit into the frame. And here's one more but very key reason against short-arms on such a steep height... the steep arm angles mean the axles won't flex up and down as easily when climbing obstacles, the obstacle will cause the axle to push the entire Jeep up instead of the axle flexing which helps the tire climb up and over much more easily. An obstacle that might give fits to a tall Jeep with a short arm suspension would be much more easily conquered by a Jeep with the same height but with a long-arm suspension where the arms are at a much shallower angle which will allow the tire to lift just the axle up and over the obstacle, rather than the entire Jeep.

Make sense?

Personally, for that kind of $$$, I'd rather see you go for a Rubicon Express, Clayton, or Rock Krawler long-arm suspension. Those are all first-tier players and you'll get more bang for your buck. :)

Thanks for the detailed response. Makes sense to go for the long arm. The RE and RK call for exhaust modification. Does that mean I can take the rear section off and jsut have a muffler welded onto the end of the pipe? or does it need to be completely re routed?

I think I've decided on the Rubicon Express 5.5" LA. Other than the exhaust modification, SYE and driveshaft, Is there anything else I will need for a complete kit?

Sb5551 04-14-2009 08:36 PM

You are gonna need or want bigger tires which I am sure you already know that, but then gears would be a good upgrade. Its not needed right away, but a good thing to think about.

haha yea i forgot to mention that. I thought about gears but i dont want it to rev too high on the highway (~70mph)

iamadam1122 04-14-2009 08:41 PM

Any recommendations for a steering stabilizer? is it needed?

sorry for so many questions i just want to get it right!

Basically just the muffler, you'll need a shorter muffler. My total muffler job only cost me $85 from a local shop, I went with a Thrush muffler which is only a tad louder than the OE muffler.

If you are going to run 35" tires, I'd go for the same cost RE 4.5" LA. I actually ordered my RE LA kit with the 5.5" springs but figured out it would have been too tall for 35" tires so I sent the springs back and swapped them for 4.5" springs. As it is, RE's lifts are always nearly an inch taller than advertised so the 4.5" lift will be at least 5" and possibly 5.5". That's why I didn't go with the 5.5", it would have been more like 6-6.5" which is just stupid excessive, especially since it gives a higher than necessary center-of-gravity. I'd only go with the 5.5" if you will go with 37" tires which would require that the front axle be replaced with something stronger. The D30 just isn't up to 37" tires if you wheel hard. :)

Sb5551 04-14-2009 08:50 PM

With gears its your personal opinion. I can do 70 mph in 4th gear at 3000rpms with my 35's. I dont have a 5th gear anymore cause of my 35's.

As for the steering stabilizer, according to many you will not need it if your suspension is set up properly. I have a rancho 4000 I think, only because my stock one was leaking fluid so I upgraded.

Just go with a standard steering stabilizer, they're all pretty much the same... a hydraulic shock valved so it has 50:50 in/out action so left and right steering is equal. RE's standard stabilizer is fine, and don't be tempted to go with a dual stabilizer which only makes your power steering have to work harder which can make it overheat on a tough trail.

With bigger tires, you need slightly higher engine rpms to compensate for them than what you'd want for 30" or smaller tires. For 35" tires and a manual transmission, 4.88 is ideal and is what I went with. With your 6-speed, you could get away with 4.56 but if it were me, I'd want the lower 4.88 ratio for some serious trail capabilities that won't wreck your highway rpms. :)

Sb5551 04-14-2009 08:56 PM

Jerry, I'll just let you take it from here.

You're coming up with good advice and ideas and you always do, your input is needed here too man! :)

Sb5551 04-14-2009 09:05 PM

Haha, I learned it from listening to you.

Anyways, iamadam listen to Jerry when it comes to jeeps he knows what hes talking about.

iamadam1122 04-14-2009 09:14 PM

hmm I guess the 4.5" is the way to go then. I have an 04 with a 5 speed. unless theres a hidden 6th gear.

I'll figure out the gearing after i get the lift done. Whats the easiest way to correct the speedometer and odometer?

Sb5551 04-14-2009 09:17 PM

You either have an electronic or mechanical speedo gear. If you have the electronic, the dealer or a jeep shop can calibrate it for you. If you have a mechanical speed sensor, you can buy a new plastic gear that will adjust the speedo.

As for which type you have, I am not quite sure.

nutsandboldts05 04-15-2009 09:32 AM

There is some AWESOME advice in here. I'm gonna subscribe to this thread for future reference. Great job explaining these thigns, and thank you for the Q's and A's everyone.

So long as you don't have a Rubicon which has an electronic speedometer that isn't easily recalibrated, it will only take 5 minutes and a replacement speedometer gear to recalibrate your speedometer/odometer. Here's how to do it when you're ready... it's less than a one-banana job. :)

Wow thanks. Much easier than I imagined. There is a ton of great advice in here its helped me a lot in decided what to do thanks guys.

jdhallissey 04-15-2009 02:39 PM

I would do a 1.25in body lift too so you can add armor.

MoA 04-15-2009 03:10 PM

if you are going to run 35s.. id go with a 3.5'' LA kit with a 1.25'' jks bodylift, the reason for the bodylift would be tummy tucks, gas tank skids, and other skids.. IMO 4.5-5'' of suspension lift is TOO tall.. i like keeping my jeep closer to the ground..

which is why im going to add tube fenders, keep my 3'' of lift and add control arms, and still have plenty of room to run 35s..

have you checked out rokmens jeep? 3'' of lift, tube fenders, and 37s.. VERY nicely set up

the next thing you have to ask yourself.. will your axles handle the 35s? i went ahead and swapped in a hp30/d44 just to run my 33s.. ill get super alloy kits when i run 35s.. just as a precaution
