As always, thanks to all who have commented.
I will use the UCAs, as they are paid for already. I will keep a close eye on the joint.
May night the bullet on the Adjustable struts, now just need to figure out from which manufacturer.

Suggestions?

I have run poly lCA bushings for years...no issues, but I suspect my LCAs are binding...just a harsh ride overall.

My plan is to try Firm Feel adjustable strutrods this winter to see if it helps at all. 

Never hear a bad thing about FFs products, so I figure its worth a try!

I have no personal experience with any of these, but I know a couple people with the PST pieces that like them. I think I will be buying the QA1 rods this winter. See what black Friday brings......

Those PST ones look good...but I guess you get into the discussion around heim joints and durability then.  :pokeeye:

LOL, yes you do.. :drinkingbud:

But they don't seem to wear out quickly there like in the control arms.   Any body with bad feedback on heims in the strut rods?

I like Firm Feel's stuff too, but...

I have reservations about the FF strut rod design. It's not really their strut rods or their adjustability, but on the poly strut rod bushings.  Normally having a stiffer bushing is a good thing, but at the strut rod it's a little different. Having the strut rod bushing be stiffer is good when it's resisting forward/aft plunge, which holds the LCA steady and keeps the caster from changing. But when it's resisting the strut rod pivoting up and down with the suspension travel of the LCA it's not good. When it does that it's acting a lot more like binding. The rubber bushings weren't good in the forward/aft plunge movement, but they allowed for easier up down movement.

That's just my take on it. Coupled with not having had any issues with the longevity of the heims at the strut rod I think the heim jointed strut rods are the better way to go.

I haven't had any issues with the rod ends I used making my strut rods.

When I put my car together I used an adjustable strut rod with a rubber bushing.  That bushing was destroyed in the first 1K miles.  So I said forget that, and bought the Hotchkis heim jointed strut rods.  It bolts directly to the k-frame with no bushing to fail.  I have had no issues with mine in the last 3K miles.  I think my car feels a bit more solid now than when it had the rubber bushing.

Take Brad's design above and use a bolt in ball joint in the strut bushing area. plenty durable, large range of motion possible.

That's what they used in Nascar and the Chrysler kit cars. :bradsthumb:  There are a few modern twists on that now

I was going to see if Howe would make a threaded pin instead of a tapered one for there rebuildable screw in ball joints as they move so nice as compared to a stock ball joint.

Picture is from Australian Jim Richards Javelin...... not sure why I took such a keen interest in the suspension on that car?  :lurking:
