I ordered a new Frankenlift with the OME790 front springs, OME HD front struts and The OME long travel rear shocks. It came to about 1k even with shipping and everything. I can't wait to upgrade. Anyone else ordered the new Frankenlift? Heather said it would be a week or two before I get it. I hope I get it before the Moab safari. :wink:

I really don't want to run my OTT lift again but a man has to do what a man has to do.

Wait, is this the long-awaited no-spacer CRD-specific lift? Awesome! I'm going to let you be the guinea pig, so let us know how it works out!

spencevans · **Posted:** Fri Apr 13, 2007 12:46 am

No spacers, The frontend has the OME HD struts and OME790 Coils which are rated for 500lbs. The rear had OME948 HD Coils with the OME long travel shocks. The lift has already been beta tested by AllJ's and they will stand behind their products. No guinea pigs here. AllJ's is the best. Heather said they had already sold a dozen or so of the new CRD lifts but they won't ship for a few days.

i can't wait till i have enough money to buy one. probly next month. i need someplace to put the MT/R's that are in my garage.

I'm curious why its so significantly more $$. The OME springs are $155, and the Daystar front spacer kit is $180. If you no longer need the front spacers, it seems that the price of the all-spring kit should actually be CHEAPER. What am I missing here?

ATXKJ · **Posted:** Fri Apr 13, 2007 10:38 am

The Frankenlift should have a small spacer - the OME spring is about a 1 1/2" lift, Frankenlift is 2 1/2"

I would expect it to be a little more expensive because the OME struts/springs are more expensive than the Ranchos

chrismc · **Posted:** Fri Apr 13, 2007 12:48 pm

The Frankenlift II is $790.99 with spacers and upgraded OME struts. If you knock $180 off that for the spacers, you get $610.99. If you add $155 for the new coil springs, you end up at $765.99. I doubt shipping was $234. It is my understanding that this lift has no spacers at all. If it does still have spacers, I have my doubts that this is actually a "CRD-specific" spring and is actually just one that they found might work a little better for a CRD.

I'd really like to see AllJ update their website with the full details of the kit, or even just post up here and actually answer ALL the questions that have been asked. So far the information about this spring/kit has been very incomplete.

All OME springs for the front of the KJ are '40mm' over stock ~ 1 1/2"

Since the CV's can tolerate 2 1/2" without a problem - most people want a 2 1/2" lift - so All J bundles the OME spring and a small spacer lift to get a 2 1/2" lift - while maintaining the OME spring - which is probably the best one available for the KJ (unless you take OzLTD's approach and design your own)

The CRD specific part is not the length, it's the spring rate - it's 500 lbs/inch, all other models are 400 lbs/inch or less (The stock CRD spring is 410 lbs/inch) - that's heavy enough to support the CRD and an ARB and a winch. - it's also a large enough wire that it may cause so issues at full extension (OzLTD's concern and why he went to 465 lbs/inch)

So in your $ calculation - add a small spacer - probably more expensive than the old - because it's low volume custom for All-J

FYI from All-J's - on the Gas Frankenlift

Front Includes:
Complete front assembled struts using: OME H/D coil springs; Rancho 17505 struts; Daystar upper strut plates, and our custom designed Poly Urethane spacers - they fit better, they look better, and they're designed specifically for your KJ!

Ok, so there is still no spacer-free lift for the KJ. That's a bummer. I'm standing by my thought that the spring is not CRD (or even KJ) specific. If they made a new spring just for CRD KJ's, then they would have made it longer so it matched the 2.5" lift in the rear. I should have known that their lift was too good to be true. No wonder AllJ has dodged the "tricky" questions in all their forum posts.

Now we just need to get a spring manufacturer on this side of the Pacific to make a spring to OzLtd's specs.... If we combine that with some OME shocks/struts, we should have a REAL spring-only lift.

Not so... this spring is CRD specific and KJ specific and that is why it is only 1 1/2 inches. The springs and struts are made/designed by ARB/OME and are not made by All J's.

OME made this spring to address the heavy CRD and to make a spring that would take the CRD + their ARB front bumper with a winch.

ALL the OME springs for the KJ have been 1 1/2 inches higher than stock springs-- regardless of if they are for gas or diesel. OME did not provide more lift in the spring mainly because they felt it would stress the CV joints too much and render the vehicle unable to accept alignments within factory specs. OME is known for making smaller lift components that are superbly engineered-- they often do not make really large lifts as they would not be able to sell them worldwide due to lift restrictions.

All-J is using the springs from OME, along with their own parts-- to get the most lift for the buck. No, it is not an all spring lift, but neither is the Frakenlift. Do note that that the Frankenlift is a proven lift and it will keep up with any other commercial lift kit out there for the KJ.

ATXKJ · **Posted:** Fri Apr 13, 2007 8:20 pm

Actually the best all spring suspension out there is the OME.

The Frankenlift just takes that, and makes it an inch higher.

It will probably get you more than 90% of the capability of an all spring system at 1/2 the cost of designing your own

That's not a bad compromise.

This lift is not posted on the AllJ site at this time. The lists you see on the AllJ site are the old CRD Frankenlifts. To my understanding the new Frankenlifts for the CRD do not use daystar spacers. They do use some of AllJ's costom parts and the kit also comes in different levels.

It can be had with exclusively OME components (HD front struts and long tavel rear shocks) for $954 plus shipping, I think they will call this the CRD premium Frankenlift II.

It can also be had with Rancho components for arround $814 plus shipping, they will probably refer to this as the CRD standard Frankenlift II.

From what I have seen the CRD Frankenlift is only $15 more than the gas Frankenlifts. My guess that this is a result of the additional time it takes to compress the front springs. I could be completely wrong but I think this info is pretty accurate.

So you are having Them assemble the struts for you? Could that be the additional cost?

OzLTD used the same specs as OME but used a heaver wire. His custom springs are the same hight as OME and he has around 3 1/2 inches of lift with only a 8mm plate on top of the strut with no other spacers.

Yeah, it just take more time for them to compress a 500lb spring versus a 400lb spring. So to answer your question yes they are preassembling my springs and struts.

rs4mtnitro · **Posted:** Fri Apr 20, 2007 7:16 pm

They don't normally assemble the struts so if you want them to it costs extra.

Hello from Moab! The price difference right now is basically the cost of the springs. We also have to use a different top isolator which **may** effect the price.

We are not going to build custom springs for the CRD or the gas kj's. We are using OME because they are the best. They work and are high quality. We only added the extra inch. The volume of the KJ springs is such that it's not cost effective for ARB or All J Products to build custom full length springs.

Spencer and DieselDave have CRD frankies riding in our JK for hand delivery as soon as we meet up with them in Moab.

I'm sure we will hear from them soon.

See you soon, back to wheelin' in Moab..........

what does the 500lb mean for 500lb springs b/c to the lay person who doesnt understand suspention like me.....

my rough calculation in my head works out like this:
4300lb vehicle

2150lb front
2150lb rear
(making asumption that vehicle is 50/50, which it isnt but this is benefit of doubt for simple math)

(2150/2) = 1075lbs per wheel

500lb spring per wheel seems way too soft.
what does 500lb spring mean?

taking what i know of springs, the more you compress them the more force it takes to move it the same dist.
is 500lbs the starting force to compress it at all?

thanks in advance,

o8k

Weegie5 · **Posted:** Wed May 09, 2007 12:32 am

The basic equation for springs is
F=k*x
where F is the total force, in this case the 1075 lb; k is the "spring rate", for these springs it's 500 lb/in; and x is the distance the spring compresses/stretches in inches. Solving for x gives 2.15" of compression.

So a higher spring rate means a stiffer spring and a lower spring rate equates to a softer spring.

Not knowing the uncompressed length of the spring, all this doesn't mean much. You can assume that if a spring rate of 500 lb/in gives 2.15" of compression, and if those springs without the spacers give just 1.5" of lift, the stock springs (with a spring rate ~410) are longer uncompressed than the OMEs.

Please pardon if my math is a bit off, I'm in a hotel room using my cell phone as a calculator. You get the idea...
