Kore or Lorenz ?

Any ideas on which is better ? They seem similar. Does Lorenz use progressive rate springs? Any ideas on Sway-way versus Fox shox ? Also wondering what people are paying. Any advice appreceated.

Lorenz is coming out with his progressive spring soon, he says. That's what I just read on the "other" site.

After installing my Kore Chase system, there is a small improvement on the pavement. Cornering is better. Everythings seems tighter. Intersection dips are not an issue at speed. Freeway expansion joints still cause truck to feel very bouncy. This is something I was hoping to get rid of. I was under the impression, and after to speaking to Kore, that there would be an improvement on the freeway. If there is, it is very slight.

Off-road, the improvement is substantial. It really soaks it up. When you do hit hard, the rebound is minimal. Much more control. Very nice.

I have not read any complaints about Lorenz system from those that have installed it.

I have the Lorenz, I like it.

The ride is more controlled on the street. The bumps done resonate through the truck. The shocks just soak them up. I use the nitrogen pressure to adjust the ride on the street to suit my tastes. Currently about 180 in the front and rear. For off road, I would prob move it up to 220 or so. I tried 250 on the street for a while, way to rough.

Off road, I can take the washboards over 60 and not have any issues.

I have the 2.5 SwayAways. They handle great and i have no issues with them. I have not tried Fox. My take all these shocks are similar and all cost about the same. Sean uses the SAW because it gets to use the full 10" travel. He would of had to limit the travel if he used Fox or King, i.e. a new longer bump stop.

As for the IR Coils, as I understand it, they are about a month out. I should have some the first week or so of May. I have no complaints on the ones I have, the new ones just sound cool.

Which is better, well mine of course, LOL. I have not ridden in a truck with the other systems. I guess I have no comment on that.

As for price, Sean’s is plain and clear on his web site. You can also build it as you go. I felt the Lorenz system fit my price perceived performance goals. It exceeded that.

Let me know what else I can answer.



lots of pics in gallery

in the end choosing the setup that suits you is your choice, try to go for a ride in trucks with this suspension and form your own opinion.
i personally own a trex race and a kore race, both are flawless.

i personally feel that the fox shock is the most superior shock on the market. nriver stated that he gets a full 10 inches out of his 10 inch shocks, yet if it is a 10 inch shock giving 10 inches of full wheel travel i feel it would have to have a metel hitting metal situation. in the photo that nriver has posted the res hose seems to be touching the top of the coil bucket, this is bad. eventually it will wear a hole in it, something to be addressed.

if it comes down to money the lorenz system is probably the one for you,if not i would go for the kore system. my customer service has been second to none,kore carries product liability insurence. does lorenz? kore stocks all products and it is a product that has been proven. my 2 trucks have a combined milage of around 50,000 hard miles on them. i have bent rims , blown tires even bent a dana 60 housing , but the suspension is fine.

you allso may want to check thecarlisuspension.com
goodluck and what ever you decide i am sure you will be happy,
anything is better then stock.

I do need to re mount my resi's. Just have not gotten to it. My fault not the shock or sean. That will be part of the work when I pull the springs.

Sean has posted many times on many mesage boards about the 10" suspension travel. Do some searches on that point.

But I do agree. Get what you want and meets your needs

Another plug for Sage Carli....his system is dialed in. He uses Kings, I've run my Kings for about 25-30K and I'm really happy with them. It's all in the valving (Don Thuren valved mine, but Sage is just as good). Arguing King vs Fox is like arguing Bud vs Coors, not much difference other than the taste. The Kings are a little cheaper.

Lorenz claims a full 10" of travel, but only with the OEM rubber bump stops. OEM rubber is way too soft and one good weekend will shred 'em. I have other issues with his approach that I won't go into here.

KORE stuff is great, it's proven but I think it's fairly over priced depending on what level of kit you get.

I have not seen any photos ar evidence of stock bumpstops being shreaded with the Lorenz system. No one has commented to having that problem. I would think we would hear it.

I also checked my hoses again. They actually do not rub, but look like they do. I will be moving them in the future. Putting the Resi up higher.

Last photos I have seen about the SwayAways showed 10.5 inches of travel with the suspension at full droop. The photos I have seen of other systems show 9 inch or so.



Im not sure what is proven about the Kore system. Their race truck ran 3 inch shocks to run baja. http://www.race-dezert.com/forum/sho...t=14308&page=3 Good thread about the Kore setup.

Ridgetop, did you get any of your questins answered? Or just a bunch of us saying mine is better?

I attended a Rattlin' Rams event yesterday and Sean confirmed the IR coils are about two weeks away. I hadn't seen his shock towers up close until yesterday and they look substantial,especially at half the price of the competition. The new foxes with variable compression settings are really unique giving you the ability to dial in your ride for road conditions and load. There's a lot of good product out there,choose whats best for you.

No hydro, still happy with the box. Hardest part of the install was getting the DSS and pitman arm off.

Ask any fabricator, to base a performance suspension system on using the OEM bumps, and then claim travel number around that is ludicrous. The durometer of the OEM bumps is way too soft and there's not enough shock absorption in them to adequately dissipate the energy when they're hit. A few good hits and they're gonna come apart. The poly bumps are better, but not by too much. There's a reason why KORE uses the longer poly bumps (and in two different durometers), and at least he's found that reason by actually doing R&D. If you're gonna run 50-60 MPH through the rough stuff in a 7000lb truck with 10" of travel, you're gonna land on the bump stops.

That line about needing to be caged if you're gonna be on the bumps is an excuse. I've seen several sets of OEM and poly bumps shredded.

nriver, I have another question for you. Sean couldn't/wouldn't answer it, so maybe you can. I see those pictures were taken with the coil out and the front suspension at full droop. How much space is there between the top of the coil and the bottom of the bucket at full droop?

I read the thread on race dezert, it's a re-hash of the same garbage about "KORE's Race System isn't the same stuff Kent ran Baja with". Right, it's not, but KORE's system is proven in that it does exactly what it's advertised to do and he's got alot of satisfied customers out there, including some folks that have forgotten more about this stuff than you or I will ever know.

again, how can you show 10.5 inches on the shaft from a 10 inch shock.
not possible, or is it a 12 inch body shock. its very simple please explain
industry standard would be to limit the shock 1 inch in the up stroke and in the down stroke, so as to not do damage to the shock.
can you pull a rabbit out of your 10 inch shock as well?

nriver in the photo you have so kindly displayed it does not look to me that the tape is resting at the bottom of the shaft , on top of the pretty red parts.
please post a pic of it measured correctly with limit straps installed in the correct place as to not let the shock bottom on its self thus causing damage to your fancy new race shocks. i have never said that one suspension is better then the outher, or that kore offers more travel etc. yet there are a select few that keep saying kore shocks bottom on themselves and that the lorenz system is better. yes i own kore systems and i love them. yet i would like to know why your choice is better, is the cost? yes its cheaper, yet i would allso say it has components that cost a lot less. nobody has answered my question about lorenz having product liability insurence. does he carry any? that is why his system is cheaper. but dont tell me its better.
sean challenged greg from drc to a race in the woops at glamis, yet greg challenged sean to a race from 29 palms to laughlin and back.wich race would give a system more validity. log some hard miles on your truck, go out and break something, thats how these guys do it.
sorry if i am ranting , i just cant take the B.S anymore.

I have never made any comments about a suspension bottoming out. I have just been replying to questions posted here.

Have these systems bottomed out, or tore up the bump stops. Not that I have heard of. Not that I have commented about.

The 10.5 inch I stated was with the shaft mounted bumpstop.

shock specs from the manf.

King 2.5 10" Comp 18.375" Ext 28.375" Travel 10"
Fox 2.5 10" Comp 19.5" Ext 29.34" Travel 9.93"
SAW 2.5 10" Comp 16.75" Ext 26.75" Travel 10"

So it looks like they can get the same travel from different sized shock bodies. Just pick the one that is best for your application.

you will need to go through their specs to fine the numbers, but they are there.

again, hope we are helping the original poster with thier question.

I will do some more measurement when I get back in there soon. It would be cool to see other suspesion measurements. Off to play in the dirt.
