heavy duty rear springs for fwd avant

[jbh]

My dads managed to break a couple of sets of rear springs in his avant.
he uses it to carry his tools about. ( tbh he would be better of with a van!! )
he does carry a fair bit of weight so weve been looking about trying to get heavy duty springs.
any recommendations?

Probably Genuine Audi is the way to go? They're probably breaking because they're cheapy aftermarket springs, they're pretty **** things.

They do a couple heavy duty options, will need careful scouring of the parts listing to find them though.

The Audi Spring codes are thus:

1BA Standard
1BB Heavy duty (20mm higher)
1BC Special purpose
1BD S4
1BE Sport
1BP Heavy duty (same height as 1BA but with limited bump)
1BT Heavy duty (7mm higher)

But theres also a weight category that goes along with it, if you get me that category from the service sticker, i'll look up a part number for you. The weight category should be something starting 0Y, like 0YA or 0YC etc.

I run my B5 with sports springs (20mm lower than standard) and I'm lucky if I get 3-4 years before one of them breaks. This is genuine Audi parts (not cheap at £75 each plus VAT) and that's going back to 2012 prices, since I last renewed them. I tow a 750kg unbraked trailer a few times a year, and this must play some part on the condition on the springs.

Our salt-laden roads over the winter period don't help either. All that's protecting these new springs is a thin powder-coated finish. Pressure wash them regularly and check the condition.

get eibach springs. Ran them in old a3 with boot full of tools and towing for over 6 years and no problems...

I did suggest this to him but as he is in and out of the quarry hes not wanting to lower it any.
he says if anything if he could raise it a few mm he would be happy...

 

[ruairi83]

Eibach do the pro kit and it leaves the car like sline drop if even. 10-15mm max.

I compared springs and they where a lot thicker than standard Audi springs.

Other than that he needs customs springs from someone where online.

hes ordered a set of munroe heavy duty springs so we will see how long these last... he got a discount on them from the local auto shop as hes bought about 3 sets of springs off them so far.

Would it suit to buy coilovers for the rear and upgrade to a higher spring rate?there are loads of companies that make 2.5" springs in different lengths and rates then you could have it at whatever height you wanted.

Both, me and aragorn, have been looking at changing springs on h&r coilovers. Rear springs are actually different ID at the top and bottom, so other than custom made springs, really difficult to find something to fit.

well see how he gets on with the munroe springs. I think hes decided if he breaks one again hell try the eibach springs. he says hell stick a bigger profile tyre on...

where can I find part numbers for the 1Bt springs with a pr of 0yr-oyt? Any help would be appreciated

I just spotted this old post from 2015 - and I've bought a 2004 A6 1.9TDI Avant (PD130) 'final edition' the build sticker states I have:-
"1BE" springs (factory sport) and my weight code looks like its "OYD"
The car looks a bit too low to me for towing despite having a tow pack fitted (I would have loved the early C5 Allroad I spotted, but couldn't live with the MPG of the V6 TDI as I go up and down the M4 quite a lot, otherwise it was my idea of the perfect utiltiy car)

I am looking for some more suitable springs to refresh what could be age-related tired old factory originals (or perhaps replaced with the wrong springs at some point by a previous owner) as the car still only has 55k miles from new and is otherwise very good.
going on the above - I am looking for either 1BB, 1BT, or 1BP to improve the ride height and carrying/towing potential to launch the RIB in summer.
Can anyone point me to either the correct weighted OEM or aftermarket springs for this car to tow with. Happy to buy a new set of 4 or just the rears initially.
Thanks

Can’t help you with the correct spring choice, but I used to have a B5 A4 2.5 TDI V6 Quattro Sport that I used to tow with, RIBs funnily enough.

Here was my Amtrak locomotive before I sold i at 173k. You’ll see the sport springs aren’t that low. Key thing to remember with Audi is that the tow ball nose weight limit is usually only 80kg or so. Obviously you have the weight of the outboard to counterbalance, but if you load up with passengers and kit that’s where the weight plays havoc with the springs.

You mention the C5 Allroad. You can still pick them up, but they are relatively rare now. I used to be on an Allroad forum, and the majority of issues were related to the air suspension.
