Hello all

Just wondering if there is any "heavy duty" rear springs available for a 56 plate fabia estate. 

Reason being  I tow a fair bit on some rough tracks and I'm finding the rear end is grounding and would be looking to raise the back end a few inches. 

Thanks all for looking

What is the OEM part number of the current rear springs?

 

It might be 6Q0511115M which is coloured coded 1 orange dot, 2 yellow dots, 1 orange dot.

 

The Skoda parts catalogue lists four heavy-duty rear springs for the Fabia MK1.

 

6Q0511115AC or 6Q0511115AD would be the obvious choice to upgrade 6Q0511115M where it's currently massively sagging...although do bear in mind that if the 6Q0511115M is sagging through age and use, such a big upgrade as the 6Q0511115AC or 6Q0511115AD might not be needed, ie. just a new 6Q0511115M.

 

Although 6Q0511115AD might be best when towing with a heavy caravan/trailer, 6Q0511115AC might be slightly better when not towing. 

 

6Q0511115AC is about 15% stiffer than 6Q0511115M, and although the specification of aftermarket springs matching 6Q0511115AD isn't listed I suspect it's about 20% stiffer than 6Q0511115M...or it's possible that 6Q0511115AD could be the same stiffness as 6Q0511115AC but with a slightly longer uncompressed length.

 

If you are not upgrading the front springs, my suggestion is to try the 6Q0511115AC first because that is a big change. The reason that I haven't mentioned any aftermarket standard ride height springs that are stiffer and/or longer than 6Q0511115M is because there aren't any...at least those that are listed in the Skoda Fabia MK1 parts catalogue. This might be because the Fabia MK1 is now an old car, with the resulting year on year reduction in choice of aftermarket springs.

Hello Carleton. 

A big many thanks for the comprehensive reply, very much appreciated, I'll have a look and see what's currently on it but guessing they are the original springs and have been compressed "a lot". Many thanks again 

Sorry, Carlston

I've found another alternative that you might want to try first, ie. before the 6Q0511115AC and 6Q0511115AD increased ride height springs.

 

These are standard ride height springs from the Fabia MK2 that should fit the Fabia MK1. They use about 1 coil turn less than the 6Q0511115M, ie. about 7.75 coils turns instead of about 8.75 coil turns. This should make them about 15% stiffer and a similar unladen ride height to new 6Q0511115M springs...but when you add on the weight of the heavy trailer will compress a lot less.

 

You will notice from the listings on autodoc that the KYB RH5539 and Kilen 65050 are each sold to replace six or seven different OEM part numbers, so you don't know what OEM part number they match. However, KYB RH5539 lists the specification and both KYB RH5539 and Kilen 65050 have photos showing the approximate 7.75 coil turns...and because the Kilen 65050 lists similar OEM part numbers to KYB RH5539 it seems that the two springs will be very similar to each other.

 

Because of a slight uncertainly of the Kilen 65050 specification, I would probably choose KYB RH5539 in preference...due to the specification being listed. However, it's always worth taking careful measurements of any spring before fitting such as uncompressed length, wire diameter, number of coil turns, weight, outside diameter, etc. in case once fitted the springs turn out to be too stiff, too soft, too long, too short, etc. Then replacements can be ordered before taking the old springs off.
