Forget about cutting springs!!!

[Matt]

Well its about time Bilstein made these for our vehicles!!! These 5100 series adjustable struts have been available for other vehicles for a LONG time!

So now I know, when I put my SL on i'll get these to more easily increase my ride height without screwing around with cutting coils. :cool:

Heck yeah! Do you have a link? This would be the way to go for anybody that wants have a modified SL!

Just type the part number (24-225793) into google. Jon should get these in his SA store too!

These shocks are great for a replacement to spacer lifts where people also swap out struts... just get the 5100 adjustable and be done with it.

Are these supposed to go with OME springs in place of the SL spacer?

If you're looking to add height to the superlift, I would not use these with OME springs Or the spacers.

They achieve lift by adding pre-load to the spring (like the SL spacer does). So i'd ditch the spacer, use stock springs, and set them at the 1.5" lift setting for a 5" superlift, or 2" lift setting for a 5.5" superlift.

That just flew right over my head. I need a beer...

Actually, I'll bring a bunch over next time, and you can lecture to me, Professor. ;)

[Matt]

lol sounds like a plan.

Hell, bring over a set of those shocks and we'll throw them on :cool:

[Matt]

OK I'm rethinking my "no cutting coils" stance.

Crunched some numbers and here's what I think would be a great addition to the superlift spacer:
5100's with OME MD springs with 1 complete coil cut.

The issue with stock springs is the spring rate is lacking for added accessories... so some stiffer springs are desirable. The OME HD springs have a rate of 630 lbf/in. If I take an OME MD spring and cut one complete coil off, the resultant spring rate will be 600 lbf/in which is nice because it adds load capacity over the stock springs but still won't be as stiff as the HD's.

Ideally i'd hope that the OME MD springs, with one coil cut, and 5100s set to .75" would put the superlift right around 5"....then you could get 5.5 or 6" by adding preload via the 5100s.

If its too tall, more could be cut off the spring... i'd say bring it up no further than the OME HD rate of 630 lbf/in.

[Matt]

Standard OME springs:
OME990 = MD = 14.56" free height , 8.9 coils, 530 lbf/in, 18mm wire
OME991 = HD = 14.37" free height, 8.9 coils, 630 lbf/in, 19mm wire

More info:
Cutting ~1.5 rotations off the OME MD springs brings their rate up to 630 lbf/in, and a free height of 12.10"
Cutting ~1.0 rotations off the OME MD springs brings their rate up to 600 lbf/in, and a free height of 12.92"

IIRC, the spring compartment in the stock/OME struts are ~11.75" long. The 5100s are going to have a smaller compartment since they add pre-load for the lift, so the 12.10" length of the 1.5 cut OME990 spring is OK.

So would you still run the SL spacer?

Absolutely. Everything im posting is my brainstorming for getting 5-5.5 out of the superlift. Previous discussions have all been about cutting the minimum amount off the coils to "get down" to the desired ride height. These new struts allow a simpler approach via cutting more off the spring to start, then adjusting "up to" the desired ride height by adding preload.

The other good thing is you should be able to adjust ride height without disassembling the strut. Hell, I bet they could be adjusted on the vehicle with a bit of creativity (compress the springs via floor jack under LCA, install spring compressors, drop LCA, move spring perch up, reverse procedure) :cool:

I'd be curious what the final ride height would be with 1.5 coils cut, and the 5100s on the lowest setting. Anyone want to be the guinea pig?? :confused:

[stites-xk]

Okay I got it now. I was confused there for a second . On a side note these would be good for added weight like steel bumper and a winch and so on!

Wouldn't you still have to use the 4 inch spacer Superlift supplies with the kit since its making up for dropping down the LCAs? Matt are you getting the word spacer confused with the preload spacer Superlift adds on top of the coil? Or are you talking about the 4 inch one that bolts on top of the strut.

Edit: didn't see there was a page 2 on this thread

[Matt]

Yeah I sounds like you've got it correct.

Must still use 4" strut spacer
I would remove superlift coil spring preload spacer, regardless of which spring is used (unless more lift is desired and the 5100s are maxed out)

[07JeepXK]

Hmmm now I just wish I had the money to do this!

Hey man.... i've been chatting it up on JF about using the 5100s w/MD cut coils in the superlift for 6". I you could get a deal on the parts, would you want to test it out?

And Mark (lekmedm)... similar situation for you. The vendor wants to know if the Superlift + 5100s (and stock springs) would net 6" of lift but he needs a someone to test it. I can do the install for ya. After we verify if 6" is possible we should be able to set them back down to the standard 4" lift you currently have since the lowest 5100 setting is .75" lift, which is about what the superlift preload spacer adds (so we'd just take that spacer out)

[stites-xk]

I can test it both ways! With stock springs and the new struts and with the MD springs! I have everything laying around at the shop! So the question I have is what kind of deal are we talking about?

PM me your email. I'll have him email you directly.

I'm half tempted to sell my OME HD setup and run these 5100's with cut MD springs now...

[paroxysym]

say I run a XK hemi coil in the front with a rusty strut spacer, I'd set these to the 1" position to accommodate the added height or would setting them to the 1" setting add to the 3/4"-1" I'm gaining from the XK hemi coil and strut spacer?

[Matt]

Setting them to 1" would add to the height.

Id try running the hemi coils with the 5100s on the lowest setting and leave the 1/4" strut spacer off.

[07JeepXK]

I could use new struts. These might be in my future prior to tires. I have to replace my coil isolator a while I'm at it. They are shot. What's the price on these struts?

[stites-xk]

Their like 230 or so a pair!

Hmmm just googled that part number and it says $119 a piece at shock warehouse

[stites-xk]

Its cheaper than the OME struts!

Oh you said a pair. I thought you meant for one. Yeah they are cheaper. I might order them today

Matt was talking to a supplier on JF that wanted somebody with SL to do some testing and I volunteered! It's up a couple of post!

really?

i asked this on JF, but setting this shock up to 1" with a stock coil to obtain some extra height- wouldnt that cause premature wear on the shock with no supporting mods for that extra height? or is that what its made for?

im baffled by this shock and the options with it

[Matt]

No. I really think you're missing the whole premise of how this shock works. Lift is achieved by relocating the lower spring perch to increase the preload on the spring. Nothing else is needed.

gotcha... so i could run a set of hemi coils with these 5100s set to 2" and then in the rear run a OME coil with a set of bilstein 5100s in the rear (i know these arent adjustable) and achieve a 2" lift?

Sounds right to me. You would be getting about 2 or so inches of lift front and rear running that setup. And even if the front sits a little higher than the rear or rear higher than the front spacers can be added to get it where you like it

[Matt]

^^ yup

[paroxysym]

awesome... something to think about.

thanks guys

[Matt]

^^ I'm contemplating selling my OME HD setup if you're interested. Would be Front & Rear springs, front struts fully assembled with all new components (new when I put them together, i didn't reuse any of my stock mounts). All you'd need is a set of rear shocks... but I have Scotts rear 5100s sitting in my garage that he'd probably be willing to sell.

I'm just really interested in playing around with the OME MD + adjustable 5100 combo. My goal would be to get 3" lift on the highest 5100 setting so that when I get my superlift I can drop it down to the lowest or middle setting for the 5-5.5" im looking for.

[stites-xk]

I'll have a set here soon :D

Sweet!

What are your plans? Going to start with the stock springs?

[stites-xk]

Yes I'm going to start with stock springs and set the shocks at 1 to 1.5" of lift and test for about two weeks with a off road test! Then move to the OME springs and set the shocks to no lift and test them that way. Then I'll do a write up and find out what I like more!

with this set up, i was wondering if the hemi coils would be more compatible as with a set of MD or HD springs?

[JustinS]

After putting on the RR spacer lift I'm pretty sure I need new front struts. I was thinking of going the 5100 route.

I need more front lift as it is so can I pair these with my RR spacers?

[Matt]

Yup. At the lowest setting you should get ~.75 more lift.

[JustinS]

Excellent!

[07JeepXK]

I love how the title of this thread is "forget about cutting springs" and Matt's about to get 5100's and cut some OME springs hahaha

[Matt]

Lol I was thinking that too!

In my defense I wasnt thinking about keeping the increased spring rate which is where the other thread comes from.... ideas are always coming man! :)

[paroxysym]

has anyone ran these on the highest setting with OEM springs? if so what were your measurements with these? im ready to order my rear springs and id like to match them with the front heigh of hemi OEM XK coils on 5100s adjust to 2".
