OP, I'm curious where you sourced the extra spring collars from? I've got HD's on my car (installed by the PO) and I'm pretty sure mine only have the single collar as well. I'd like to duplicate the double locked configuration.

I pulled them off my rear pss9`s. I called Bilstein and as usual Bilstein USA never has any spares in stock-everything has to come from Germany. My front pss9`s have been with Bilstein since last October waiting on parts for a rebuild

I wasn't aware of USA dealers that offer the lock rings. Hopefully someone will post a source for them here.

I may be bringing back an old thread here, but in looking at the above photo, the bottom drop link mount only has the single locking collar. I thought the concensus was to have a locking collar on the top AND bottom to avoid any lateral movement?

I just recently purchased 2 additional locking collars for my HD/H&R install and I'm noticing that there's not enough threads to do a top/bottom locking collar on the drop link mount, plus the spring perch collar, and a locking collar below that. Am I missing something? Did I buy 2 extra locking collars for nothing?

Thanks.

Here is what I have on my car, belts and suspenders because I want all the insurance that can be had that there will be no issues at speed

double lock at the bottom perch and double lock on the sway bar perch top and bottom

I agree, but as you can see from my picture below, I don't have as many threads on my shock body as yours. So all my threads are taken up with the double locking collars on the drop link mount, and a locking collar under the perch. This doesn't leave me any room for height adjustment, unless I take out one of the locking collars.

using one too many collars. the perch is threaded, use that to lock against one ring and use the 2 others to set the spring height.

To rephrase: You are at the bottom of the adjustment range for that shock.

Ok, so THIS should be the correct way then....I didn't realize that the bottom of the threads of the shock body actually create a "lock" for the bottom of the drop link mount, and then lock it on the top with a collar. Then this will leave a space for adjusting the ride height between the drop link mount and the spring perch & locking collar.

For street use you don't have to be as finicky
But I wouldn't leave it like that

if that is the height you want raise the swaybar perch so the the perch or it's top lock nut is the second lock nut for the spring perch. You might even have room to use the other lock nut under the swaybar perch

Alternatively there are sway bar perches that are high and lower than that
Here is an example w/ 3 different ways to attach the link

I get what you're saying. But if I want to lower the height of the car after installing the shocks, then I have to take the whole assembly out of the car and make the adjustment, as opposed to having room to adjust the height without disrupting the drop link mount. I guess I just got conerned about any lateral movement of the drop link mount after reading some posts on here. But like you said, if I'm using the car basically for street-use/spirited driving on occasion, should I be ok with the single lock collar above the drop link mount?

Get a shorter spring, they arent that expensive...

I dont know the specs on the stock spring, but Ill bet there is someone here that does (cough BV.. coucgh BV)....

Isn't your droplink mount threaded? mine was. I don't even have the extra lock ring on my car, it was "optional" since the kit didn't have them. I would not bottom out the drop link mount on the strut shaft since it will invariably not be in the right position. I do keep telling myself i'll go back and put that lock ring in one day, should really buy a set for when that day comes.

Thee problem is: if the line of force from the swaybar isnt directed exactly sqare to the droplink it will cause the mount to rotate out of position and break the droplink.

The origonal design was to use a single lock collar but they would still tend to rotate. The current wisdom is to lock them both top and bottom. This seems to work pretty well.

If you dont have any lock rings in place, I would bet you already broke a drop link and just havent noticed....

I have H&R springs that are going on, so from what I've read those are pretty low springs already. My concern is that if I set it up like my picture in POST #20 above, then I have no adjustability of the spring because I've used up all the threads.

Does anyone have any measurements using H&R springs of what the height settings need to be with the spring perch and drop link mount to achieve various ride heights (e.g. RS, RS+10, etc.)?

See now you are going to make me drag *** out to look at the car to see if its moved at all. I do recall the single lock collar. I recall tightening with a metal punch to get it just right.
