Triumph TR6 - Ho, ho, ho...

It's that time of year again - time for a freebe. I have a nice set of used polyurethane TR6 differential bushings with no wear that I'd like to give away. Nothing's wrong with them - I've just converted over to a LS differential and no longer need them. They have a slight "set" to them, but 10 minutes in boiling water will get rid of that.

This is a nice upgrade, and all I ask is that YOU use them. Don't turn around and ebay them - if I wanted to sell them, I would. This is meant as a gift to a member. Drop an email if you're interested.

You're at it again! Thanks again for the solid steering rack mounts you gave away last year. Merry Christmas to you!

Now....for all the TR6 guys (and gal, where is the lady from Seattle?) looking for an SUV that more fits your taste in transportation....check this:

And if you haven't been to this site before, there are some old TR6 and Triumph racing articles. Paul Newman, Bob Tullius, Group 44, that kinda thing! Web page for the other articles:

Enjoy, and Merry Christmas!

Which limited slip are you using?

Would I would be correct in assuming from this that you have taken the plunge and spent some brass with Mr. Good? If so, what ratio differential did you go with and what is your take on the conversion? If not, did you go the torque sensing or clutch type route with a TR differential?

Here's Santa for those of you who didn't run across him already.

Thanks for the links, the TR6-up is pretty cool. Is it a targa/surrey roof (sorry.. hood) panel? Makes me think of doing a kind of cartoon PT cruiser thing with the TR4. Or more of a Magnum kind of wagon. Tis the season for dreaming....


Yep - got the Goodparts conversion - Nissan R200. The old diff starting making too much noise before Thanksgiving. I was going to stick with the original diff, but TRF didn't have one to send back. I would have had to send in the old for rebuild. That swayed me.

The GP kit is quite good. It's 3.69:1, and works fine. Just did the test driving today. Bought the shortened DS, too. Replaced the polyurethane trailing arm bushes with the GP "nylatron" - again - the GP kit is very good. I'd have gone with bronze instead of SS for the bushings, but so it goes. The washering system is excellent.

Hi Brent,

if you still have these diff. bushings I would be graeful to put them in my car... total restoration of a '76. I would like to offer you, regardless of whether you still have the bushing or not, a custom set of lever arm shock spacer washers of whatever thickness you choose. ( these increase the compression adding stiffness to the ride but without undo harshness)I think that the spirit that you have made this offer is terrific and sets a trend that is very possitive... and TR guys are certainly that!

Best of the Season to All,

Cheers, Rob

I took my TR6 down for some extensive work and decided to take the same plunge while the car was off road. I have installed the unit (also the 3.69:1 along with the shortened drive shaft), but a test drive is still some time off while we continue to work away. The brackets for the conversion are well thought out and diff practically jumped into place. I also bought the Nylatron trailing arm bushings and the adjustable trailing arm brackets. I did my usual change out of hardware to AN/MS stuff for the fasteners loaded in shear. Since we "built structure" when the diff mounts were reinforced some time back. I did have to chuck the rear diff mounts up in the lathe and take about 1/8" of thickness off to compensate for the extra metal to ensure good engagement of the thread locking feature on the rear nuts, no big deal.

I must admit that I was intially puzzled though regarding the large bushing holes on the R200 diff housing near the nose as most of the Nissan R series diffs I have seen either had small holes and no bushings or were carrying bushings. When I looked at the GP website, I recalled those having a bushing in them so I thought that I had some missing bushings and checked them out at the local Nissan dealership. I don't recall the exact price they said because my brain just stopped processing all the words when he said ninety....dollars and .....cents each. I had to go across town and there was another Nissan place very near my destination. I asked them (wanted to make sure that the other guy had indeed picked the right item since he sort of struggled with the look up), same thing, the brain just stopped processing all the words again after the ninety. I then contacted Richard Good on the matter and told him of the bushing price and asked of the materials I was thinking of using, what was his take on all of this. He responded back that there was indeed no bushing used there for his set up and that he must have a small fortune in Nissan 300ZX Turbo diff bushings in his shop. That is what his washering system is all about. I offered up a one "word" answer for him at that point, ebay.

I agree with you on the SS bushing sleeves and am still up in the air on those. I will probably go ahead and use them instead of making up some bronze ones, but will apply solid film lube to the fastener along the grip length. The way I see it, the resin bound molybdenum disulfide of the solid film lube (Dow Corning 321) and the cadmium plating on the fastener should be sufficient to minimize any tendency of the sleeve/bolt to gall.

Next project is to fabricate some solid rear anti-roll bar mounts and finish up the rest of the rear end misadventures......then to the next phase. Hope it is all done in time for British Car Day at Chateau Elan.

I would not use any bushing that are harder than
the aluminun swing arms ,unless they are fitted
with some sort of bearing on the pin shaft
Swing arms are getting hard to come by
Nylatron is the way to go
