Strut Arms have been installed and tested...success!

Built a second prototype of the dual link lower control arms or Strut Arms.  These units fit 65-66 Mustang and 62-65 Falcon/Comet.  Ended up going with spherical bearings instead of urethane bushings for the inside LCA mount.  The spherical bearing cup threaded shaft is offset below the cup center to provide necessary frame clearance as the Strut Arms travel up and the suspension compresses.  Added steering bumps too.  Ball joints are Moog K772 screw in units torqued to 125 ft-lbs with threadlocker.  Ball joints are replaceable.  Strut rods are the same hardware as used on our adjustable strut rods (SR-1001) except a shorter adjusting tube is used. 

We plan to design and build Strut Arms for 67 and later cars after these are in production.

Took off the old hardware (LCAs and strut rods) as one unit, measured their length and then pre-adjusted the Strut Arms to match. 

Installation of the Strut Arms was simple.  Fitment and clearance was excellent.  One issue arose which was that the edge of the plate was too close to the sway bar so it was notched to provide more clearance...lesson learned for production units. 

Here is a pic of one side installed before notching the plate for the sway bar.  They look and fit great.

Test drive was a success.  Steering and suspension felt great.  The alignment required no adjustment...I got it that close when I pre-adjusted them based on the measurements from the old hardware.  Plan to perform more rigorous tests before i declare complete success.  I hope to have these in production soon.  Planned price is $499 for the pair.  Compared to a competitor that has something similar for over $700 and that aftermarket adjustable lower control arms and adjustable strut rods bought separately would cost much more, these will be a very cost effective alternative providing excellent performance.

    The last details are being worked out. Plan to debut them at the end of January or early February. Yes, they work with Boss 302 style lower cross members

    One minor tweak…the front strut rod mount bracket at the frame (where clevis mounts) will use an elongated hole to allow the strut rod angle to change as the length of the strut rod is changed. Once it’s adjusted, then the clevis bolt is torqued down to lock it in place. Have to get some new brackets made and then production will begin. Shooting for later this month (October) to have units ready for sale.

    The Strut Arm is essentially the melding of the adjustable LCAs and adjustable strut rods into one consolidated part. Screw in ball joint is the biggest difference which is easier to replace, but ball joints are still Moog and your ball joints should last for years. They still have the same basic function and they both use teflon lined rod ends for smooth operation.

    Looks like I bought my lower control arms and strut rods too soon. What is the advantage to this set up over the traditional control arms and strut rods?
