I have read alot of threads with people asking whether or not Mugen bushings are the same as oem or even oem ITR. And I have heard alot of people who reply, "DO A SEARCH, THIS HAS BEEN COVERED BEFORE!"

Can someone please direct me to a thread that isn't worthless? I have never seen a single thread with durometer results comparing OEM versus Mugen bushings. But I have read alot of threads with B.S. conjecture.

So if someone could please direct me to a thread with durometer results or if they already have them, I would be very grateful.

Thanks in Advance,
Conlan

Why do you think that is? Perhaps, just like you, most people don't have access to a durometer, and don't want to buy one just to test the Mugen vs. OEM difference.

I'll tell you what, get me access to a durometer, and I'll direct you to a future thread with durometer results.

I have Mugen bushings on my DC2 ITR. They seem to be stiffer than OEM Honda DC2 ITR bushings, although composed entirely of rubber, judging from the appearance. They were a great solution to my bushings problem, but of course it's hard to tell just how much of a solution because the old bushings had 90,000 miles on them.

King Motorsports is very good at answering questions, and this user works for them and would be glad to answer questions, I'm sure: https://honda-tech.com/zero...00618

IMHO, they are a relatively cheap solution to suspension geometry problems that develop as our cars age and wear out the bushings. Installing that big bushing will be a pain in the neck, of course. I am glad I had somebody else do that for me.

I will test Mugen, OEM and a new third party OEM replacement with a durometer next time I get a chance. Have to borrow the durometer, but shouldn't be a problem.

Installing them isn't that hard. Can be done with a hammer and a home-made pipe ring tool. I found it easier than using the press. It is important to bevel the edge of the bushing that you're pressing in. Makes it 10 times easier.

Also I guess SP has a new tool for replacing them, that shaves a lot of time out of the process.
Tool Kit 65100.

Here is the tool in action, although supposedly only have to disconnect the bushing's two bolts, which would save some time even over what this guy did:

Thank you very much for your insight. I am planning on buying them from King, and I have heard from King that they are harder, I just wanted some quantifiable evidence. For such a stark difference in price between OEM and Mugen it seems important to me.

That would be very nice of you to do. I am not sure if your post would be deleted for some odd reason. Yes, I am sort of a conspiracy theorist. But would you PM me when you get the results.

So you obviously don't remember a thread that already did the testing? It's weird, people in past threads always refer to the fact that the testing had already been done, and can be found. But I can't find anything.

My buddy has had that tool for awhile. He worked for Honda and when they began selling the replacement rear trailing arm bushing (the big one), and he had to buy it. It makes things sooo much easier.

What company makes an aftermarket rubber bushing for Hondas?

Thanks a ton!

 

go to any Screen print operation worth it's weight in salt, I am sure they would let you run a durometer test on the two bushing(make sure both are new) I am sure the results are going to surprise

 

ive not seen anyone test their mugen bushings. i dont see any reason for a conspiracy... :rollseyes:

and you dont have to. they are physically stiffer when you compare.

im talking SPECIFICALLY engine mounts, suspension control arm bushings - upper and lower and front and rear.

the trailing arm bushing has their own story i wont repeat. you can search that.

vitt has his own contradicting story about the upper shock mount bushing. i dunno about those. ITR are simply the stiffest available for sure anyway.

 

If rotten wants to test the (non-ITR) Mugen DC2 upper shock bushing against a OEM from the Acura dealer I'll be glad to send him one of my Mugen. It's new, but it's been sitting here for a couple years.

Personally, I would like to see as many comparisons as possible.

 

Any more info on when you will have the time?

 

Did anyone do the test? I would love to see the results.

Join the club. Rotten you are making me sad. Are you still alive.

 

I was always told that the upper shock mount bushing (the bushing in the tophat, correct?) was identical to the OEM DC2R bushings.

I think this even use to say so on an old version of the webpage.

vitt would disagree with you on that. unless he got the wrong part...

just get the ITR ones from the dealer anyway.

Are the Mugen's supposed to be stiffer? On both sets of my NZ coilovers they came with those bushings. I compared side-by-side a set of the new Mugens to my set of new OEM ITR and I could not tell a bit of difference.

But what's wrong with using the ITR stuff if it is that good? No need to re-invent the wheel.

 

well this is his story.
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Vitt1 &raquo;</TD></TR><TR><TD CLASS="quote">Not sure about all of them Tyson. I bought the Mugen upper shock DC2 bushings a few years ago, and they feel very soft. In fact, I kept the ES upper shock bushings in the front of the car, and since I already had changed the rears I left it as is. I still have them somewhere but I have to look for them.

I know you're local and a fellow S2K owner, so maybe if I see you at one of the meets I'll bring them and let you take a look at them. I can't say 100% sure that these upper shock DC2 Mugen bushings are indeed repackaged Honda OEM, but I sure felt cheated when I paid about $35 plus shipping for 8 of these things, when I think the OEM DC pieces are less $3 a pair (at least they used to be).

Besides, the guy who helped me at King didn't know what he was talking about when I asked him if the Mugen were the same as the ITR upper shock bushings, and he told me yes. Obviously they are totally different, but that's what I thought I was getting.</TD></TR></TABLE>

I bought upper shock bushings for the DC2 and that's what I got. I know the ITR are completely different. But I found that out after I bought the Mugen DC2 bushings. What I said about the ITR shock bushings is that when I asked the salesguy at King, he gave me incorrect info about ITR and the regular DC bushings.

But my point was the Mugen DC2 (non-ITR) upper shock bushings (which I got in a Mugen bag) do not feel any stiffer than the stock Acura/Honda bushings from the dealer.</TD></TR></TABLE>

 

The normal DC2 tophat bushings are waaaay softer than the DC2R tophat bushings.

The bushings that came with my Mugen NZ coilovers were in a Mugen bag and were identical to the OEM DC2R bushings that I had. Both are very, very firm bushings.

 

well, like i said, i have a complete set of ITR bushings. i know what they are. yes, they are stiff, cant imagine anything stiffer and still be called a bushing, and not a thick metal donut.

What about OEM crx bushings? Are they really sitff, like you say about the ITR bushings, when they are new?

 

no.

ITR bushings that we speak of are half metal, half stiff rubber. completely unique.

Oh ok. Do you know how rough the ride is with mugen bushings compared to OEM? I don't want my car riding to much rougher as it is daily driven and pretty stiff already.

 

no idea. havent installed them. i just like to accumulate parts... really.. its a sickness.

it could only make it rougher.

Do you want to sell them?

Here is a pic of the ITR bushings that Tyson speaks of. It's a little hard to tell but they have metal embedded in them:

I borrowed these pics that were originally posted on a old thread by member descartesfool. on one of the bushings the middle was drilled bigger, I think to accommodate Koni shocks.
