Didn't know exactly where to put this...a "suspension" category would be nice...


I've posted this link in a couple of other threads regarding the Nivomats, but here it is again for anyone who's missed it...

http://www.cadillacfaq.com/faq/answers/pdf/nivomat.pdf

This does a good job of describing how the Nivomats work. Don't worry about the fact that it's on a Caddy site, it's written by ZF Sachs and applies to all of the Nivomats (they make specific models for each line of vehicle - part of the reason that they're so expensive).

thanks for the post, interesting reading. My Mag has them and I used to have a BMW motorcycle in the UK that had a nivomat shock on the rear end, worked great and kept the headlight well aimed.

Does the load leveling in the tow prep option include the Nivomat shock?

so will they fit my 95 sxt 3.5 AWD? and you just bolt them on? no wiring, controls or external pumps needed?

cool.

i have had benze wagon with the leveling system. it is great on them but very complicated compared to this.

Nivomats are all internal action. So, no wires, pumps or controls. It is amazing that they will always seek the correct level no matter what the load. That is why they do not work with lowering springs.

AWD vs. RWD = 1" different ride height. If you're thinking of using the RWD stuff on a AWD, I think you'd have to install the RWD susp. (springs/struts/shocks) from all four corners. If you only use the RWD Nivomats(rear shocks only) on your AWD car, the AWD springs will be fighting the Nivomats as they're tuned to sit at a specific height and spring rate. This is why you can't use the Nivomats with stiffer lowering springs(Eibach, etc.).

Um..no. The rear ride height is raised also. Just look at the rear of a RWD and AWD next to each other and you will notice the difference. The suspension parts in the rear are mostly the same except for the springs and shocks which are uniquely tuned for AWD, the knuckles, the camber links, the sway bar, the halfshafts, but the main thing that changes the rear ride height is the factory spacer washers in between the rear suspension craddle and the underbody.

Has anyone actually lowered with the nivomats? After skimming throught the document I came across some interesting things about lowering with Nivomats:



A further advantage of the Nivomat-suspended axle results from the possibility to
decrease the overall spring travel while still obtaining the same or even a larger
dynamic spring travel (Fig. 4). This is often used especially in lowered vehicles.

I got the tow package springs and shocks from dupie 24 and we put the shocks on my 06 RWD. Got an inch to 1.5 increase on the rear.

Works well, and I'll fill the wheel well gap with larger tires, maybe 65 or 70 series. The SC will adust for the difference.

Loaded a ton of stuff for a charity thing, and the heigth stayed the same.

I'd suggest going with stock shocks, or kit, if lowering.

I would love to put a basic lowering kit (springs only) on my Magnum RT and get some 20" Torque Thrust M's, but when I went to check the application of the Eibach spring sets they exclude self-leveling suspension models (which my RT has). I quickly browsed the Nivomet article and I didn't see anything obvious preventing it... did I miss something? Is Eibach just covering their butt or will the lowering springs really cause a problem? I do tow a rather heavy boat with my RT so the load leveling is something I really need to work, not just a bell/whistle. Advice? TB

I have and it did NOT work!!! with H&R springs (#50866) that claim that it will lower the rear of the car 1.4"

I called H&R and all they could tell me is "oh well it worked here with a Mango we used for R&D..." they also said H&R have sold TONS of springs for this application but could not furnish any references to back their statement.

Bunch of BullSchitt!!! I will take this to court if I have to... b/c this is FALSE advertisement period.

Novimats Modded for Lowered Springs... Finally (http://www.lxforums.com/board/showthread.php?t=82316)

Thanks for that link, obviously what is needed is a simple kit that will lower the nivomat upper mount like he did along with a cut oem spring. That would keep it all in check and lower the car.

You would think one of the suspension companies would figure this out. I know they all say the nivomats are junk but fact is they work well for their intended purpose that many people enjoy.

I would think more important than spring rate however would be to lower the upper mount "exactly" the same amount the rear is dropped. The measurement would have to be derived by removing the nivomat and measuring the mounting top to bottom, then install your lowered spring and drive the vehicle a few miles to settle the spring (no shocks) then again measure the shock mounting top to bottom and modify it exactly that amount.
If I were to try this, that is how I would do it.

edit Well after reading up more specifically about the nivomats it appears they use a much weaker spring to begin with. This not only compensates for the added pressure the nivomat provides but also allows the nivomat's pump to function correctly. Tighter spring rates of a lowered spring would give much less wheel stroke over road conditions.
From Nivomat:



The mechanical spring must be dimensioned weaker than a damper solution, as
indicated above, since the Nivomat takes over a portion of the spring force.

Looks like a better solution would be a shorter (oem spring rate) spring along with the upper mount mod.

If you can see the rear shocks in the wheel well, the Nivomats should have "Sachs" printed on them as the manufacturer. That's what it says on my '08 Charger R/T R&T.

Here is the part number info for the NIVOMAT Self Leveling Shocks...

Also, if you look at the bottom of the shock, where it mounts to the suspension, there is about a 3/4" post that comes out from the bottom of ths shock tube and connects to the "eye' that the bolt goes through. If the mouting "eye" is welded drectly to the shock tube, you don't have self leveling shocks.

Hope this helps,
Bob

They will bolt right on. You might want to get the matching springs, too.

I installed them in our RT Magnum and it took only a couple of hours.

Yeah, the springs are a different part number. They didn't appear to be any longer, shorter. I'm sure they have a different spring rate...

I was fortunate enough to purchase a complete set of shocks and springs from a NVRDUN. We tow a small camp trailer with our Magnum and the shocks and springs really improve the handling and stance of the car with the trailer attached.

I recently bought a set of Nivomats & rear springs for my '05 Magnum R/T from someone who'd lowered their '05 Magnum. I also looked up the part numbers I received in the 2006 Magnum/300 (LX) parts PDF & after decoding all the build options, verified that they're correct & didn't change between '05 & '06 Magnums. They are:

SHOCK ABSORBER, Suspension: 4895 563AA
Spring, Rear Coil: 4895 538AA

I've had my lift tied up with another project, so broke down & scheduled a local shop to install them tomorrow.

Why am I doing this? I bought the Magnum to tow things. First my pop-up camper, & now we've bought a JAYCO Jay Feather Ex-Port 17Z camper that weighs in at 2900 lbs dry.

I hope this helps someone else doing converting to the tow package suspension as it took me about 3 evenings of digging to find & verify the part#s. Seems there's a lot of bogus info out there!

BTW, the Charger load leveling package DOES NOT FIT the Magnum: the ride heights & suspension dimensions are different.

I swapped my RT shocks and springs out for the Nivomat damper/spring package so I can tow with my Magnum. While the ride height is a bit higher, the improvement in performance when towing is a fair trade-off. My wife actually pointed out the difference. I didn't notice it at all...

They may have a different #... BUT, the Nivomats work in conjunction with a specific spring rate to perform the leveling function.

I have Charger SRT8 nivomats with Magnum SRT8 rear springs (with Charger SRT8 front spings/shocks) on my '05 Mag. RT. They're the same rear spring rate, just 1/2-3/4" taller. Car rides and sits just like a factory Magnum SRT8.

From all i've read, the Nivomats work off the spring rate for leveling, and the spring height sets the ride height(as with any other vehicle). My car would ride like a brick truck if this weren't true.

I suggest you read in more depth. The external spring is optional depending on vehicle weight, it just offloads some of the vehicle weight from the Nivomat. The Nivomats have height sensing valves in a vehicle specific fixed internal position. The Nivomat's piston actuates the valves when in the appropriate position.

Not even 2k. Its pretty light.

You don't even notice you're towing the thing! We had to slow down going up the grade from Bishop to Mammoth/June Lake!

We're towing with a bone stock RT Magnum, except for the K&N FIPK intake...

We're going to take the trailer out of storage in a couple of weeks to do some work on her. I'm planning on taking it to the scale and I'll have a firm number. I'll be sure to post it :)

Verell
03-19-2010, 10:24 PM
Wow, that's really light, especially for '50s construction! Will be interested in seeing what it weighes in at!

I've been towing a'93 Jayco popup that weighs about 1900 to 2000lbs. Know what you mean about never noticing it was there, even on some long fairly steep uphill climbs. I couldn't measure the popup's effect on cruising gas mileage: a pretty consistent 22-23 mpg going about 65. But each stop & start would dropp the average about 2 mpg!

Where the popup was really noticable was stopping. The popup did't have brakes, so the Magnum had to stop everything. Never as sign of brake fade, but you could tell you were stopping with a much heavier load. Extra pedal force & longer stopping distance.

The new camper is going to be 50% heavier than the popup, with 480 lbs tongue weight. It will have electric brakes which should make a big difference in stopping. I expect the big difference to be the much greater wind resistance & it's effect on mpg.

Hmm, I'd think the Shasta would have about the same wind resistance as my new camper. What kind of mpg are you seeing when towing it?

Just got back from a 2-day 'shakedown' trip towing our new Jayco Feather EX-PORT 17Z camper (17', GVW 3500 lbs, Hitch: 360 lbs).

Went 63 miles to Quinebaug Cove Campground, Brimfield MA. Mix of about 1/3 freeway & 2/3 hilly state routes.

Towing went very well, no problems.

Campground was OK, tiny sites, but at least had a pull-thru site.

Magnum was awesome:rock:, had no trouble pulling the camper, easily cruised at 55-60, had reserve power for passing if needed, no problem stopping. Gas mileage wasn't spectacular: 11.3 MPG for the trip. I've got a n eX-Cargo rooftop carrier that I'm going to add for the next trip. It's the right height & shape to serve as a wind deflector like the big trucks use. Should help gas mileage when highway cruising.

To avoid downshifting each time we started up a hill then upshifting when coming over the top & down, I selected 4th gear. 5th gear did pretty well on the freeway except would downshift for steeper hills.

Beside the camper talk, is everyone straight? I like campers!

Nivomat's are matched to a spring rate. Stock R/T spring with Nivo's shocks raise the R/T over an inch, but ride fine and perform as intended.

I think the Nivo rear spring is weaker on the R/T as it looks the same as a stock R/T coil.

You still can't lower with a Nivo, but you can raise and fill the wheel wheels with a 265/65/18 tire that gives it a raked look and adds near a MPG.

I'd like to raise the rear or rear and front of my RT Magnum.
A coworker of mine has a newer 300 Touring AWD and it definately sits much higher
Another coworker of mine has a newer SXT Charger with 17 alloys and that one sits lower than the 300.

Can I simply add those space washers? and keep the rest of my suspension the way it is?



Um..no. The rear ride height is raised also. Just look at the rear of a RWD and AWD next to each other and you will notice the difference. The suspension parts in the rear are mostly the same except for the springs and shocks which are uniquely tuned for AWD, the knuckles, the camber links, the sway bar, the halfshafts, but the main thing that changes the rear ride height is the factory spacer washers in between the rear suspension craddle and the underbody.
