billy shocks comparison

[Ceeker]

I recently bought a set of HD's which looked to be correct, but when I compared the set on the right, there is a NOTICEABLE difference. I was told the set on the left are also HD's but as you can see from the pic they are narrower and shorter. Would someone be able to tell me what the left might be?

Left 45mm housing, right 51mm housing I would say

[Ceeker]

but why is there such a difference in length?

Not sure about Billies but I know with Koni Sport you can order shorter travel for low springs.

Have you got the part numbers off them to cross reference?

Well, they came out of a 86-325es with stock springs.

You can always call Bilstein and give them the numbers from the housings and they'll tell you everything you'll want to know about them and more.

Did you try calling Bilstein? They do have phone support and I am sure they can run these numbers in their internal database and tell you. Why not go to the source?

Like somebody above already mentioned, it is for 45mm strut housings, but will work in 51mm struts. They are just an OEM Bilstein that comes in some Sport package cars. I have a few of these kicking around too. My friend also runs a set of these, revalved to Grp. N valving in his track car.
