2014 OEM Springs


Recommended Posts

You could probably dial the Konis up to the point where they'd be unpleasant, but even keeping them on full-soft will get rid of a lot of the floaty feel that the stock '10-'12 shocks give. I'd go with the Konis if you have the means of installing the inserts (or want to throw your friendly neighborhood GTEASER a few bucks to assemble them and ship them to you), otherwise definitely go with the KYB replacements over the OEM parts.

I had put Koni/Eibach on my 2.5i and drove it with them for about 15k miles. I bought my GT used and the prior owner had installed 10-12 replacement KYB with Eibach springs. I swapped the KYB for the Koni into my GT. Koni's rode and seem more composed that the KYB. At this point and time I have about 40k miles on my Koni's. They are very nice and compliant for a street vehicle.

 

The KYB are a good budget strut. They rode better than stockers when I paired them back with the stock 10-12 springs on my 2.5i before I sold it. I would imagine the 13-14 springs would pair well with them.

My boots look perfectly fine at 100K miles and don't show any signs of deterioration. My rear mounts have 100k, My front strut mounts were replaced by the previously owner with a performance set. If you have higher miles I might be tempted to replace the front and rear strut mounts. I have not seen anyone replace strut boots on the 5th Gen from failure. I have a 2009 OB an haven't notice anyone replacing the boots on those either, so I suspect they are relatively robust.

Probably it was discussed 1000 times, therefore I will try to be as brief as possible.

I got a 2010 2.5i model, VIN 4S3BMBG68A3233546, which comes with that "floating feeling" stock suspension. It's about time to replace it and I want to get rid of it the budget way.

 

1. First question is: 2010-2012 vs. 2012-2014 suspension - are they fully interchangeable?

 

2. If no: Should I go for KYB 2010-2012 instead of stock one?

 

3. If yes: Should I buy stock 2012-2014 or KYB 2012-2014?

 

4. No2 and 3 lead to the next question: Are there different part numbers for KYB 2010-2012 and KYB 2012-2014 or they produce just one part applicable for both models?

 

5. Additionally: I suspected that the rear springs need replacement too. What are my option in this case - to upgrade to stock 2012-2014 springs, if they are different? Also, I noticed that there are different spring part numbers for 2.5 and 3.6 engine models. Are they really different?

 

Thanks

From what I gathered here the 2013-14 springs are 15% firmer than 2010-2012, that should take care of the floating feeling without making the ride too harsh for most people.

 

Thanks. Probably this is what i'm after.

 

I'm still wondering what will be the difference between the springs for the same year model, but with different engines, as 2.5 and 3.6 - they have different stock part numbers. I suspect that they are the same, but follow different numbering only. Well, you never know.. :icon_neut

The stock springs rates are different to account for the engine weights of the 2.5i and 3.6R.

KYB has separate part numbers for the 10-12 struts shocks than they do the 13-14.

 

This thread discusses as someone followed up on the 13-14 vs 10-12 KYB's. there is info from KYB about them.

Hello guys.

Still in search to replace my 2010 springs to the better 2013 ones. One problem for me though - I'm currently live in Europe and there is no cross refference table with the European parts, therefore part number 20380AJ10A cannot be found around.

My only option is to ask for some help - could anyone can tell me the exact dimentions of the 2013 rear springs like overall lenght, thickness and outer diameter, so I can find their European twin? Or if someone has the stock number for their KYB replacement for example.

Hello guys.

I found an option to order springs from US and ship them to Europe.

Therefore, I need you quick expertise.

 

There are two options for an upgrade of my 2010 ones -

20380AJ14A for the auto trans

and 20380AJ10A for the manual trans.

 

Assuming that they have same size, but different stiffness (or maybe not, but just a different part numbers) - Which one shall I choose for my CVT 2010 upgrade?

From parts.subaru.com, the AJ14 one is for an outback

 

For the legacy, 20330AJ10A for front springs and 20380AJ10A for rear springs

For the outback, 20330AJ14A for front springs and 20380AJ13A for rear springs

DrD123 Allow me to gently disagree with you.

 

Talking about rear coil springs only, from what I collected from https://parts.subaru.com as info:

 

20380AJ10A is designed for:

Subaru Legacy 2.5L 6MT 4WD Premium Sedan 2013, 2014

Subaru Legacy 2.5L 6MT 4WD Sedan 2013, 2014

Subaru Legacy 2.5L CVT 4WD Limited 2013, 2014

Subaru Legacy 2.5L CVT 4WD Limited Sedan w/EyeSight 2013, 2014

Subaru Legacy 2.5L CVT 4WD Premium Sedan 2013, 2014

Subaru Legacy 2.5L CVT 4WD Premium Sedan w/EyeSight 2013, 2014

and 20380AJ14A is for:

Subaru Legacy 2.5L CVT 4WD Premium Sedan 2013

Subaru Legacy 2.5L CVT 4WD Sport Sedan 2014

https://parts.subaru.com/p/Subaru_2013_Legacy-25L-CVT-4WD-Premium-Sedan/COIL-SPRING-REAR/49230093/20380AJ14A.html

 

Whereas the same 2013 year Outback has 20380AJ12A and 20380AJ13A

 

**************

My request for help was based on what I found on another website http://www.subarupartsamerica.com

20380AJ14A - spring Legacy, auto trans

20380AJ10A - spring Legacy, manual trans

https://www.subarupartsamerica.com/parts/2013/Subaru/Legacy/2.5i%20Premium/?siteid=216122&vehicleid=382452&diagram=7526725

 

Obviously we need more opinions on the subject. I really started to think that these 10A and 14A are just the different numbers for the same part. Or maybe not....

Interesting; it looks like the 5th Gen Sport had different spring rates than the regular 2013/2014. I would assume the sport variations are a little stiffer but who knows, maybe Subaru soften them slightly for the 18" wheel and lower profile tires than 16" & 17" the rest of the line up got. You can try look them up in FSM to see if any differences are listed.
