328 shock absorbers
1 - 18 of 18 Posts
Hi Tiff, was quoted £340 + vat each through dealership, and Bilstein won't supply direct, tied to dealer network !! They do offer a refurb service £85 but can't guarantee delivery back before 6 weeks ! Talk about between a rock and a hard place ! Just think it's a bit steep for a non adjustable 20yr old design, a plain shock absorber. Koni did them for 308 series but not 328, still haven't found any other manufacturers yet. Am waiting on qoutes from some friends abroad, as Bilstein sell in America, but only the red uprated road version not the yellow sports option that was fitted as standard . The search continues.......................
Cheers Gavin

Hi Tiff, thank you for enquiring on my behalf, asked for the serial no both from the dealership and Bilstein but neither would divulge the secret !! Knowing other people who have rally cars from similiar era, their replacement costs seem to be around £80-150 per shocker, indeed the American quote was for four ! front and back, just over the price for 1 in total here ! But as stated before they were the red road shock.
The annoying thing is ,that it is only one shocker that is causing bother, and that it is eminating a clicking noise but seems to have no bearing on its performance ,no harshness, no weaving when exiting corners under power, just the annoying click, right behind your head !!!!
Obviously would be replacing both rear shocks at once, and as i use the car through winter when poss, being of the road for 6 weeks minimum is a bit of a pain. Am awaiting prices from South Africa and Italy, so when they come through will pass them on. As motor factors are concerned everyone i have checked with just seems to draw a blank. to be continued........

Not sure if they are available new, but Koni was a standard equipment on I believe, most US spec 328 GTSs. My 89 GTS is on has Konis.

In Keith Bluemel's "Original Ferrari V-8" book, he lists the Koni shocks used in each model and for the 328 they're:
Front: 82-2336
Rear: 82-2335
Gavin, are you absolutely sure that it is the shock that is making the "clicking" noise? There are many heavily-loaded parts moving about that could be making the noise. The drop-links for the anti-sway bar can break (it has happened to a few 308's I know of), which will cause the bar to slap the suspension arm, or maybe it's bushing (or another bushing in the suspension system) has split it's rubber portion and the metal sleeve is hitting the bushing shell.
Hi Peter, many thanks for taking the time to answer, after stripping down he rear of the car, yes i'm sure it's the rear shock, as switched sides and the click re appeared on the other side. Checked every bush and every moveable part. The last resort was to swap sides and he presto there it was.Seems to eminate from the top of the unit.
As of yet have not found a UK supplier listing Koni's to fit a 328, my one is a late model ABS (89).
Checked with fastboys web site ( thank you ) but couldn't find anything suitable there either.
My intention was to replace both front and rears as well as bushes all round this winter, to tighten the old girl up !
But it seems to be at quite a price !
Thanks Gavin.:crazy:

The difference between the yellows and reds are that the yellows are adjustable.
The US spec 328 GTS DID indeed come with Koni shocks.
I found the models that Peter posted here in the US for $145.53 from eshocks.com

That's good to hear you've positively identified and isolated the noise and narrowed it down to the shock.
That sounds too good to be true! I just checked Koni's North American website and they don't list anything for Ferrari after 1985 and I know after checking my own car, they want a small fortune for a pair for the 308 GT4 and only the fronts are available!!
That doesn't mean they didn't make them for the 328 originally, but that even THEY don't have them available currently.
That's why when I started my suspension rebuild project earlier this year, I had no choice but to rebuild/restore the ones I had. Thank goodness Koni used a non-pressurised design and they truly are rebuildable. Except for a couple of specialised - but commonly available - tools (spring compressor, pin-spanners), I was able to do it on my own. Oddly enough, these use basic, standard hydraulic seals and O-Rings sized in inches, not metric. Everything was off-the-shelf. As indicated in that 328 pdf file posted, the oil used is standard hydraulic AW/ISO32 oil.
Gavin, I hate to break it to you, but nothing is cheap with these cars! As mentioned earlier, you may have to have your current shocks rebuilt and at that price you quoted, sounds reasonable to me. Just make sure they're experienced... Downtime is unavoidable! My car has been off the road now for almost a year...
As for the Bilstein shocks that are currently on your car, I seem to vaguely remember some mention of them being used on the 328, although all of these Koni references - including mine! - seem to contradict this! I wouldn't be surprised, or put it past Ferrari for equiping a small batch of 328's with them. They are a business like any other and for whatever reason (like a delay with Koni producing shocks, or maybe Bilstein undercut them to get some business!), a few cars were probably equiped with them. They used GM Delco alternators for the 348 because they got them cheap and we all know how that turned out (failures and thus, the recall and Nippondenso replacements), Pirelli's delay with tires and a small batch of F40's wore Bridgestones instead. Etc...

I just checked Keith Bluemel's book again and sure enough, the Mondial t's used Bilstein shocks (BA5-7006 & 7007, front & rear respectively). And the reason being, the shock damping could be changed via a console-mounted switch...
So this shows they did have some supply arrangements and would have been close, time-wise to your car being built (the t's debutted in '89 with chassis number: 79596).

The fact that it may be too good to be true is stated in the little "K+" notation...meaning it's a special order part... 
Best thing to do would be contact them and ask about the availability. Perhaps they have a 3rd party supplier that has some in a warehouse.
But, at least SOMEbody lists them with a corresponding price. That was the first place I found them after about an hours' worth of searching.
SURELY, an alternative can be found. Just look for an identical length, stroke, and heim.
I can find a plethora of sources for 88 328's here in the US. But, not having a 328 to measure for myself, I wouldn't want to dictate the potential differences between an 88 and 89.
On the specs, it looks like two different sets were used. Although I'm not understanding their numbering system. So, I don't know if it denotes GTS/GTB or year to year changes made...or something else entirely.
Of course, if budget weren't a factor...you could always go for the fully adjustable Moton dampers that are used on the GT cars.
I KNOW those would work...but they're in the neighborhood of $10,000+ USD for a set of 4.
But, paying attention to the sponsors on the race cars can give you sources for good parts. Has for me in the past.
*edit* - Here...just found a set of the Motons...

...a little more than I thought for a 328. $11,695....ouch.

Koni Dampers 82 2335 and 82 2336 are the optional dampers for the Bilstein fitted cars. Maranello Concessionaires has these in stock for £199.65 plus vat so your local dealer should be able to supply at this price. Ferrari part numbers are 13684 for the fronts and 130729 for the rears. Bilstein was original fitment for Euro cars.
If you need any more info you can contact me at [email protected]. We are the official Koni Service agent for the UK so I have a lot of damper info on all the Ferrari models.
