Custom AMC front A arms
Im looking to get custom tubular control arms for my Hornet
Since its a strut rod design im thinking the better route would be a 1 piece lower like how ridetech did the mustang arms vs separate strut rod and lower
Now my question is whats better for the lowers bushing type
UMI Rotojoint
Or
QaI Endura XM chromoly heim joints/rods ends
They both have the similar material race to help isolate wear and vibration
Delrin vs teflon/nylon

Do you plan on making them yourself ?
I corresponded with ridetech about 8yrs. ago regarding arms for AMC's but I think they were too busy and the AMC market is too small. Maybe now they will?
I stuck with the stock lower and used a modified johnny joint for the arm and a ball joint for the strut rod. I have seen quite a few rod ends used. I also built a custom upper using delrin bushings. This was all 7-8 yrs. ago before freakride.
Honestly if I had to do it again I would just call Freakride and be done with it. They get rid of the strut rod. If you stick with the strut rod and use a bushing on the lower arm and try to crank up the caster it will just tear up the bushing (delrin or urethane). Total Control lower mustang arms fix this issue. I duplicated what they did. I think ridetech mustang arms relocate the ball joints to increase caster. I also did this with the upper arm on my design.
Long story short, unless you are willing to re-engineer both arms you won't be able to dial in much caster. At this point Freakeride starts looking pretty good. Better spindle w/ more brake options etc. I'm not sold on the r&p they use but maybe you can still use the saginaw box.

Freakride is overpriced for what their m2 kit is..
For same price id rather get a full weld in front clip from AME
And for their modified stock, they dont seem to lffer an el carte
Theirs a guy in theamcforum who made a custom upper but he didnt bother tontake advantage of using say a howl tall ball joint or Chrysler screw in nor built in negative camber
But he did make it adjustable via threaded hiem joints.72 buick skylark

Yeah trying to source out the work
Id rather stick with the GM box and get rebuilt by lee or ats
Btw
Sweet arms
So you used a Johnny joint
Just on lower arms?
Both pivot points? Or just the strut rod side?72 buick skylark

I just wandered over to freakride and yes it is kinda spendy. I thought it was less but that was years ago last time I looked. AME front clip puts you into the "cant bring it back" category. Not that AMX's are appreciating much but this one was just too solid to cut.
The lower bushing is a jj ball and urethane bushing cut to fit a custom outer shell welded in the arm. The jj application is the jeep track bar. The camber adjuster bolt is 9/16.
The strut rod is a chrysler small ball joint in place of the bushing. I machined an adjuster and threaded the old strut rod.
