SVX poly suspension bushes

Hey my clamps arrived today - they are gold passivated - look really cool with the yellow bushes

Yeah those clamps are much much stiffer than OEMs

Someone mentioned that the guys from Poland would be keen to make rear diff mount bushings - if someone can measure correctly.

I cannot do that as my car is currently DD - but someone must have spare rear mount lying around ?

Thanks

The housing of these bushings is a sensitive case, you need someone with a micrometer scale and a set outside the car in order to get those measurements. It is a long shot.

I have a set outside of my car.. I will look to get my hands on a micrometer to get a measurement...

Thanks Bobby, appreciate it

The ones I purchased from Earthworm measure 2.250" in diameter. Do you need other dimensions? The center piece that the mounting bolt goes through is longer than the outside casing.

Lee, do you still have them outside the car? These should be accurately measured, 1mm smaller or bigger and they become useless.

Here are the needed measurements:

[lhopp77]

I have 6 new bushings purchased from Earthworm that I have not yet installed and I measured all of them with calipers and a micrometer. Measurements are in INCHES and not metric as that is the scale of my caliper/micrometer. (I will let you convert ) There is a slight variance in the dimensions of all the parts, so I will give you the upper and lower measurements. You did not ask for the length of the center bushing piece that the differential mounting bolts go through (Dark Blue diameter piece in your pic), but I have included those dimensions also. In my parts this center piece is longer than the main part of the bushing and extends further on one side than on the other.

It's obvious that my parts were assembled from stock tubing or bar stock with slight dimensional variations.

Dimensions:

Red 2.250-2.255 inches

Dark Blue 1.130 inches
Other dimensions of this subpart:
1.750 inches LONG
(protrudes .170 inches on one side and .080
inches on the other side of the main bushing)

Yellow .550-.560 inches

Light Blue 1.500 inches

Hope this helps.

(Oh, for a frame of reference concerning the dimensional variations---a human hair is normally between .002-.003 inches in diameter)

When I installed these bushings a few months ago mine were a bit too wide. After getting no reply here, I cross posted my question on the other forum. A little birdy over there told me that he'd had to grind down Earthworm's bushings on a few occasions, and not to worry about doing that with mine. I took a little bit off the outside of both (less than a hair, an RCH to be exact) and still had to hammer them in. They fit very snug now, and I doubt that they'd come out without using the sawzall that I took to the rotten OEM ones I replaced.

This isn't a complaint about the product. They've served me well since the install, and I can't imagine my grinding would have compromised the parts at all. Just confirming that there is a little variation between those and OEM. I'd rather they are a little big and grind them down, than too small and un-usable.

For your info, an RCH is .002 inches and others are .003. (very fine, indeed)

Actually I suspect a new OEM is right at 2.250 inches in Diameter. Wish I had one to measure.

Lee, thank you for the measurements above. The reason I was checking with you on the mm basis is because small variations between inch and mm might occur and cause a big difference here (as what happened with K Dub).

2.250" = 57.15mm for example, is the OEM bushing really 57.15? or 57mm? Here is the question...

Anyways, I will ask Chris to fab them on the 57.15mm basis, if there is any difference, shouldn't take too much trouble squeezing it in...

I agree that the OEMs are probably 57mm, but as noted they should squeeze in as that is only a difference of .0059055 inches from a 2.250" part.

But along the same line, I could see why some of the Earthworm parts were difficult to get in as they were oversize by at least twice that. (Some of them are slightly out of round, also)

Ok Chris will get back to us with a prototype in a matter of 2~3 weeks.
Patience for now...

[Johnybeas]

updates on this?? anyone ever get the extra bushings? overall impressions of the whole kit??? I won't be needing trailing arm or RSB as I have the bontaeger bar and will be getting sti trailing arms etc.
