Can anybody tell me the part number for the adjustable nut on the front suspension of my Porsche 928 S4? It's the large one that sits at the bottom of the spring and adjusts the ride height. |

I received a pair from a supplier in the USA and that's the number on them. However they are quite a bit different to the originals to look at, smaller and lighter, and the adjusting pegs are now just recesses in the aluminium. I'm sure they are correct as the supplier is the best....and he's assured me that they are right. |

Maybe your dampers were replaced? Or Porsche often changes design, make them lighter or easier to make. However they normally change the part number if they change the part. Do they look like they might fit? |

There are two nuts, one for Boge one for Bilsteins, what make are you shocks? There is also a threaded ring that you may be able to do away with to get them to work |

Please post photos of the 'originals' and the parts you received. I can compare with ones I have ready to fit. The p/n is correct for S4s. S4s were fitted with Boge originals. You have been supplied with the correct part so your front shocks must have been replaced with aftermarket at some stage. The adjusters move up and down on a threaded ring which is visible at the rear but can be hidden at the front as it's narrower, so often sits completely within the adjsuter. Are you changing your shocks or just fitting a new adjuster? If changing shocks then you have to remove the threaded ring from the old shock. |

I'll take pictures of both adjusters, I'll have to take a front wheel off as they are still on the car. I ordered new front shocks from the USA and I received "Sachs Super Touring" ones. I also ordered second hand adjusters and rings. The second hand rings are OK but the adjusters were a bit battered so I returned them and ordered new ones. It's the new adjusters that look different, the second hand ones they sent were identical to the ones on the car. I guess maybe Porsche have updated the part, as the part number I quoted above is stamped on the new adjusters. New adjuster shown below. |

They look fine - functionally same as the ones I have but they are less substantial - they don't have the flanges running round the open ends of the recesses but as long as the diameter and pitch match your threaded rings then there's no problem. |

Thanks for the photo, yes those look like my original parts. I guess Porsche must have updated the part. The threaded rings screw in fine. When I replace the front shocks can I remove the spring from the top without undoing the old adjusters (which are probably siezed solid) ? |

Yup - that's how they are disassembled regardless of state of adjusters. Use good spring compressors, then undo top nut of strut shaft and take parts off from top, noting order for reassembly. If spring is very grungy it may stick to perch at one end or other (compressor will pull it off one end). If stuck to bottom just punch the perch away. Use Optimoly TA on new adjuster and threads, also on surface where adjuster meets spring perch. When they are well lubricated the adjusters turn very easily (c-spanner) with load off suspension. Settle the suspension before measuring ride height at front, then you can just dial in the number of turns required. From memory thread pitch 1.5mm, ratio at front 2:1 so 1 complete turn = 3mm height change. Mark adjuster to keep track of how many turns you make. |

Great, thanks for that advice. I'll get on to it when it stops snowing (I have to work outside) |
