SLS Removal Thread
SLS Removal Thread
Quick update:
Having driven for some time on this setup, it has settled out nicely and drives quite well. I think it might be good to try to stiffen up the fronts a little to compensate, but that's a whole different animal... Nowhere near as predictable effects as messing with rear suspension, and I have no experience with that sort of thing.
As for the longevity of the shock absorbers in this compressed mounting configuration, there seems to be no ill effects from bottoming the suspension repeatedly, and hard (VT frost heaves at Vmax all winter).
I have some doubts as to the ride quality with the stock swaybar, though. I have a thicker rear swaybar in my TD (last one in the world, apparently ), and the combined effect of the thicker swaybar, stiffer rear springs, and 8x16s with 225/55 r16 tires cured a few flaws, but the understeer is still there, albeit muted. At least I can get the back to kick out when I want it now...
EDIT: Stiffer front springs and bar would do great things for the body roll as well. Are there special considerations to be taken into account in building front suspension? Are there good hard & fast rules for predicting what messing with the front suspension will do to handling characteristics?
Cutting the springs will increase the stiffness so using a spring from a heavier engine (S600?) and cutting it to the appropriate ride height. Also using a stiffer dampener. A bigger front sway bar without compensating in the rear will result in more under-steer. Shock/Strut tower braces or re-enforcement may be required.

Since one side of my car is sagging badly making it unstable in winter I could not wait that long and [b]have ordered a set from
propigskin at aol.com who uses a Moog spring - not sure if he modifies them - also he states that no shims are used. I will report on that install as soon as its done. Would of rather gone with the Lesjofors but gotta get it done ASAP due to winter
Did you install these yet? How did it turn out?
(07-11-2010, 09:52 AM)85-300Dt Wondered what happened to this interesting thread, good to see it back. Ended up stumbling on a peach thread where someone is selling (been awhile now) a custom wound spring for as I recall ~ a coupla hundred bucks, when I find it i'll post it, can't say i've heard mention of it here, did I miss it?

I have never seen anybody happy after removing the SLS.

I totally agree!
A second hand shock won't kill your funds.
In my opinion are the accumulators the parts that wear out over time and use. Aftermarket accumulators are equal quality, less pricey then OEM. Shocks don't last when using wrong oil, otherwise there good for decades to go. As far as I can tell there aren't any shock/spring combinations available that provide anything close to the stock set up.

(08-02-2010, 11:36 AM)Rich G I removed the rubber hose on the "bottom" end of the spring due to concerns about spring fitting into the receptacle on the swing arm-
Moog spring is an incorrect spring type - spring is not "bent flat" on bottom as is stock spring.
(08-19-2009, 04:04 PM)GREASY_BEAST(08-19-2009, 07:41 AM)Floridacyclist Can we get a parts list please? Payday's coming.
I still plan to upgrade the whole car, but that's going to wait till next year after our trip to Southern Europe. After than, I will probably be looking for a decent older G-wagen diesel.
The parts list is simply thus:
(2) Lesjofors p/n 42 568 69
(2) 300D 9.5mm rear spring shims
(2) 300D Bilstein HD shock absorbers
(1) Klann spring compressor (or a clone thereof)

Grinding the springs would not be the same. The Lesjofors springs are forged flat on the last turn or so... The Lesjofors springs worked with all the parts I listed previously. That is, all the parts in that list work together. I have no idea what the Moog springs' dimensions are..
I hope everyone is enjoying my sls conversion springs. if anyone has any questions, contact me at propigskin@aol.com or on the forum...
Just had a reply from GSF:
"Unfortunately on this occasion we are unable to help with the supply
of any of the parts you have requested."
They "just do not stock the Lesjofors springs".... wonder what happened there?
I'm trying to confirm the W116 spring option.
Does anyone know the part number of the spring that (I'm told) fits?
I'm guessing A 116 324 08 04? These are heavy duty : 5.5 x 5.5 x 15" (139.7mm x 381mm)
Or A 116 324 11 04? 5 x 5 x 14" ( 127mm x 355.6mm) >> this sounds closer to W140 specs
Use with 300D HD Bilsteins + thickest shim.
A guy over at Peachparts has done this with great success but still waiting on reply/details.
And before you all start warning me not to mess with my SLS, the car came SLS-less, has an engine from a 300CD so would need a head transplant, and is not a keeper...
Thanks and Happy New Year from Australia!
Everyone still on holidays?
300TD rear springs are 6 x 6 x 16", I believe.
Standard W116/W126 rear springs are 5 x 5 x 14"? (These were used in M.Source kit)
HD W116/W126 (300SD) rear springs are 5.5 x 5.5 x 15".
Should I go with the HD springs? Which shims?

I agree.... it is like night and day compared to when I first got this beast... I dont push it too hard all that often, but itll take most turns almost as fast as I push in my other cars... certainly about 30 mph faster than the soggy stock springs... plus the ability to carry a trunk full of tools helps a ton as well...
Glad to see you are happy with the springs! Mind posting a few photos? I'd like to get a few more for my site if you don't mind

GREASY_BEAST, regarding your post #18, could you, please, type specifications for both front and rear (on 300D and 300TD), standard and HD, springs? Or point me to where I can find those pecs? I wasn't able to find those specs anywhere.
The reason I'm asking is that I'm contemplating of getting springs custom made.
Hey All,
So is there any current sources for the Lesjofors springs? It seems this thread is dated, and it seems like these springs are the ticket for my ladys 300td.
There is no part number for a moog spring as there has never been a SLS delete spring made by a major spring company. Only options are spend the big bucks to repair the SLS system, use 300d sedan springs (weak+bottoms out), Euro Spring options, or use my custom heavy duty sls conversion spring at @ 225 shipped.
Good luck!

Newbie bumping an old thread!
I'm about to attempt this GREASY_BEAST conversion for myself on an '83 300TD. I have all the parts now except the shocks. There seem to be a few too many options for rear 300D HD Bilsteins. I can find:
W0133-1910783 - B4 HD 24-007146
W0133-1614927 - B6 HD?
W0133-1612941 - harder B6 than 927
GREASY_BEAST, do you have a part number of the shocks you used? Like you I want to carry some heavy loads in the back and need something that'll keep it controlled.
I'm using monroe's that came with Progskin's SLS Delete Kit. I can load all my tools, honda engines, you name it drive around all day with no problems. I don't think you'll have any problems with any of the billie options. If I we're going to throw down though I would find some of those Koni Special D's with the adjustable dampening or the hardest billie HD's I could find.
Nice one, Kozuka - thanks! My main concern is whether the combination of hard springs with super hard shocks is going to make the unladen ride way too stiff. I know it's all a big compromise, but i want to try to find the happy medium somewhere. Do you have a part number for the Monroe's you have?
I once put aftermarket leaf springs into an old Land Rover and had to drive around with concrete slabs in the back. Not something I wish to repeat
I'm sure the hardest valving in the HD's isn't that hard now if they we're some sports that would be different and they will be shorter. The spring rate isn't bad, it has a nice little give, but it is not a hard ride at all.. But defiantly not like a big wofty tuna boat its a good compromise. Rockauto has them for $30ea.
Thanks for the good words K. Glad you are happy with my kit :-)
If anyone with a 300D or other w123 sedan wants to install my 300TD springs as a test if you want HD springs in a sedan , please email me at propigskin@aol.com. With a review and pics, I will give you a nice refund to try it out :-)
So I fitted this conversion (the Lesjofors GREASY_BEAST one, not the propigskin one) a couple days ago and just wanted to report back. It turns out I already had the Billstein HD B46-0714 installed and they're still good, so no need for new shocks.
Going into this, I was concerned about a couple of details - mainly that the springs might be too hard - they're seriously beefy - and two that the deflection of the hooks that GREASY_BEAST described might be a safety issue. I did actually take the car in to get the hooks strengthened and after a lot of head shaking from a willing fabricator, I decided to risk it.
Now that I've had it slightly loaded (100lb of tools) and empty, all I can say is WOW. This is *exactly* what I wanted. The car feels really tight at the back and even with no load and low on fuel, it really doesn't feel harsh - firm, yes - but not unpleasant. Add a little weight and rather than creaking and groaning round the corners and bottoming out on San Francisco's terrible roads, it rides with real control. It corners better, it looks level, the shocks seem up to the job (at least with a small load). I'm SO happy. Honestly, wagon owners out there, if you're looking for a great compromise, this has to be it.
The hooks didn't deflect noticeably and there's no rust on the car, so I'm pretty happy that it's safe. What a great community that I found all this helpful information that someone else took the time and effort to research!
I attach a picture so you can see the level with no load and low fuel. It'll probably settle slightly, but as you can see, it's pretty good.
I'll happily give you any advice or tips on the Lesjofors conversion.
I just drove 3000 miles up and down the West Coast with 5 passengers, 4 suitcases on the roof and the back loaded with wine, luggage etc. This is why I installed these springs, to be able to load the car up to the rafters and still get a good ride. If anything I am even more happy than I was when I first installed them. They coped admirably with that much weight, while still giving a decent ride when there's nothing in it. They've settled down slightly since the photo above.
The installation was easier for me as someone had already done the heavy lifting of taking the hydraulics out, but the rented spring compressor from O'Reillys worked fine.

time to revive this thread again.
I just bought an 85 wagon and the SLS is already pissing me off, plus everything about it is rusty rusty rusty.
Since the last posts of this thread, I notice that propigskin has updated his product list a bit to make a whole bolt on kit for about 3 hundred and change. At that price for everything, including the block off plate, I think im going to go with him vs assembling the parts.
Any recent reviews on the propigskin stuff?
I'll post this on the FS section, but the wagon I bought was missing the HP line and a few other SLS bits.
If anyone is doing a conversion, send me the unused SLS bits! I'm trying to get this beast on the road and there's never a TD in the yards.

(10-15-2013, 11:07 AM)corrieb Nothing to say on the propigskin, but 18 months after my conversion and I have never looked back. Ride is great unladen and it'll carry a lot of weight without bottoming out.
Given the amount of work involved and given the usefulness of a wagon in carrying loads, don't short-change it!

It does look really good on your wagon.
I think the prices are very comparable and the quality seems decent between both options. Pluses and minuses for me are the simplicity plus having everything in one package.
Also, I didn't really want to reinforce the subframe hooks if I don't have to. We will see, I ordered propigs stuff. Ill post back to say how I found it as a product.

(10-16-2013, 03:28 PM)corrieb It looks a touch high in the picture but has since settled to the perfect ride height.
Based on the info in the thread, I took it in to a garage to see what they thought about strengthening the hooks. They had a good look at it and told me it was unnecessary. I've since jacked up the rear many times and it looks like it holds it fine. Having said that, there's no rust on mine. If they were rusty, I'd think again. That said, a heavy duty spring, no matter who sells it to you, is going to put similar pressure on the stops.
My biggest concern was that the HD Bilstein shocks I have would be too harsh when combined with the HD springs. I'm pleased to say they're just right.

Will be dealing with this myself in the near future. Looks like the PO had issues at some point and installed blocks into the springs to get the car up to level ride height. There is a clunk I hear when I go over bumps from the rear... thinking the ram(s) are broken need to just get in the and remove them and see what I'm dealing with.
There is also a "creative" axle rebooting going on... Interestingly, I've personally put 12k on it like this.... who knows how long it's been like that before me.
so pretty pleased with the propigskin product. plug and play with no surprises and included everything, even RTV for the blockoff plate. Nice half day project, took me about 3-4 hours to get everything removed and swapped, at a nice relaxing pace with showers of rust occasionally. I think its a good value, I checked my hooks for the subframe, and though the propig spring does push down harder, the hooks held fine and were a non issue. (even though passenger side is a bit rusty.)
The only thing I changed was the bolts provided for the SLS blockoff plate. The ones provided seemed a bit long and felt like they were bottoming out, so I swapped them for some extra oil pan cap screws.
