suspension upgrade on 5th gen?

I already have a spacer under my shock now. I think it's 5mm and like you I really like it. I wouldn't mind if it were even just a tad more. But I got you on the math thing. How about themmaterial you used for the mount? Aluminum or steel? Or does itmmatter? Thanks again for all the help. Can't wait for it to arrive now so I can get busy putting it on.

 

The shock arrived today. I had planned to freshen it up with new oil and seals. But there is no way to release the nitrogen. I had hoped it would be like the dirt bike shocks I have worked on but there is no schrader valve to release the nitrogenor to fill it back up. Does anyone know if it is possible to tap some threads and install one? Thanks

 

There sure is! It is under the large silver cover on the reservoir. Use a pick to pierce a hole in the cover them pry it off. No need to put it back on, just get a tire valve cap and you are all set.

Good luck!

 

That sure is a beautiful sight to see. I was already to drill a hole in it and tap a valve into it. Thanks so much. It still had nitrogen in it so that's good. By the ks of the outside I wasn't sure. Guess you can't expect much for 25 bucks. I really enjoy working on shocks. I did a lot of them in my dirt bike days. Can you tell me a good pressure for 're-filling with nitrogen? The ball park for off road was around 150 to 175psi. I would assume it would be close for street ? Thanks again

 

That's not surprising, those Showa units hold up very well, better than aftermarket shocks in fact.

I think as you have already found out, street shocks are similar to offroad shocks in some ways but very different in others. You should charge the shock to 190-210psi. I think you will find that almost everything you learned from offroad will have to be re-learned. I do both street and dirt and there isn't much that crosses over. Good luck!

 

Interesting. I would have guess they would be very similar other than spring rates. What would be the major differences in off road to street? Another question on this shock is will I be able to get into the rebound adjuster? I think it may be broke somehow because it just continues to turn both ways not stopping. The other adjusters turn fine. Thanks again

 

It's like night and day, totally different.

Yes, it has the same access are your stock shock. If your adjuster was stuck and you forced it then it is broken internally. That is something I can fix but you would need to send it to me - not something that can be explained!

 

I am in the process of changing the oil in my 929 shock now. I have it all apart and cleaning out what use to be oil. But I know to mount this thing I'm going to have to come up with a way to extend the upper mount. I see the most common way is to fab up a aluminum extension shaped just like Jamie does. But can it not be done byjjust extending the bolt from theoriginal stock shock and placing some spacers under it to achieve the same distance? Or making the c shaped piece bigger on the sides and using the same bolt? The problem is I'm having a hard time finding a block of aluminum in the size I'm looking for. I also question my ability to mill it out even if I do find one. So it boils down to looking for an easier way to extend this 929 shock. If anyone else has done this in another way I sure would like to hear about it. Thanks

 

Maybe Jamie would actually sell you the mount? Might save a lot of time and trouble....

 

He wont, I asked.

 

Oh that's a bummer but I can certainly understand from his standpoint.....

 

Well took care of my problem for making the point. For now anyway. When I first got the shock I noticed the rebound adjuster was stuck so I put some pb on it and tried Turning it.well evidently I don't know my own strength because I snapped it internally. I managed to get to the adjuster but cannot find anyway to get it out let alone fix it even if I did. So time to order another shock. I think the actual shaft is bent as well because while I was removing the shaft from the bottom mount it was twisting off high and low. No big deal25 dollar lesson. So this time I will check it out a little better before buying one. I may just wait until I can afford to have Jamie do something for me. Might be cheaper in the long run anyway. Not to mention less of a headache.

 

Yeah, I wish that was possible because it would be a lot easier. In order for the conversion to work the shock itself must be machined. That requires close tolerances to ensure a proper fit, so it's something that I have to do here in my shop. Sorry!

 

I'm curious does the top of the shock move any?

 

Some, but not a lot. Why?

 

I managed to fix the rebound adjjuster. I have the shock back together with some fresh oil in it. What came out didnt look much like oil so im glad I did it. Now my problem is finding somewhere that can put a nitrogen charge to it. I found one place near me but they c. Only go up to 200psi. Will 200 be enough or do I need to keep looking for somewhere that can go up to 225? Thanks

 

Call a local welding shop and ask if you can tap a partially used up nitrogen tank to fill your shock. They will have regs. on hand and should be able to help you. You will need a fill valve adapter with pressure gauge.
