softer rubber suspension parts ie not urethane

[wa5ngp]

Can someone recommend a source for the softer rubber suspension parts rather than the racing urethane type? I'd like to minimize ride harshness even if means a bit more play. So far all I've found is the urethane type. I suppose there's always the dealer.:pirate:

I know I've heard that stiffer urethane is not worse. If that were the case then why have any insulation at all. Just bolt it all up.:laugh:

Dealer, MSA, Vic Brit, etc. (its not like this stuff is difficult to find)

because urethane DOES provide SOME insulation whereas solid mount would provide NONE

You DO have the microfiche CD-Rom disk, or no? If you have the P/N's for the various parts you can still get quite a bit of the stuff from the dealerships believe it or not...short of that, it (The microfiche CD) will help you find out if you have the correct part(s) if you see it on eBay. I see stuff on there all the time...Just depends on what you want to find.

As a supension specialist, I Agree that urethane can give you a harsher ride. It does depond on what bushes you want to replace. I'm not sure where you live or what sort of car you are talking about, I assume a Z car. In Australia we have some good urethane brands and some crap brands. Good quality urethane is good on sway bar pins and things, but you can't go past origianal rubber for comfort. My Genuine Nissan dealer can get some of these bushes.

tks guys. I was just frustrated that all I could find online were the urethane versions. I had some old VCB catalogs in the closet that I dug out and low and behold they are there. Interesting that the rubber ones are specified for the different sized sway bars. I suppose that there's enough softness there to make up for the different diameters.

btw This is on a 73 240. I am about ready to change the shocks (again) so I'll change the other stuff that comes of easily in the process.

Odd thing is that when I changed the shocks before I can't remember any shock stops on there and I don't see them on the VCB pix. Maybe its not required?

I think that you will probably want to put the bump stops on. Before I rebuilt the suspension on my '73, the bump stops were missing. Either they deteriorated, or they were removed during a previous strut change before I bought the car. Anyway, any bump I hit darn near rattled the teeth out of my head. Of course, the struts were bad, too, but it felt like they were bottoming out on bumps.

None of that any more, though! The suspension rebuild made a world of difference for my Z!

I was reading in the Noltec catalogue that they make a poly bushes in 2 grades. one hard and one softer (Softride range ).

check it out.

Where do these bump stops go? Just on top of the strut so the piston can't bottom out?

yup, that's where they go.

$16 poly at MSA.

actually, the OEM bump stops were affixed to the underside of the "hat" or "upper spring perch" so that they isolate the top of the strut tube from the spring perch when the strut cartridge is at full compression. They disintegrate over time.
