I have a Pure Performance track bar and itís 1-3/8 solid Steel with a heim joint on same end that mounts to the frame or drop down bracket necc for lift. Itís really a tough one but mounting bolt was sloppy. The eye in heim is .030 larger ID then the bolt holding it to the frame by design.
I purchased a bushing for my OEM track bar it too was .030 larger then the grade 8 bolt.
I have no doubts after going to Friend in Ford parts and measured the ID on every one he had all were .030 larger bore then its bolt.
My gut feeling is to give track bar ability to continue to move when the suspension has to articulate in different directions at the same time.
SLOP BY FORD DESIGN.
But I wasnít liking the clearances for my truck. So I bought 4 Grade 8: 7/8Ē x 8Ē bolts and put in the machine lathe and took skin cuts on bolt until it was larger by .005 on the bolt
Cut the rest to put 3/4 NFT threads on the bolt. in the pipe threader and I clamped in bolt and ran threads down as needed.
No damage done over 5-1/2 years in my truck and thereís only .005 bolt clearance to hold down bolt clearance where track bar gets mounted to my frame.
So again the upper mount bushing or sleeve comes worn on day 1. .025-.030 pretty consistently
Good info, thank you.
Excellent, I think they'll probably have what I need. I'll reach out.
