Trac-Bar / Panhard bar Torque Specs

[RdoubleU]

I'm torquing my rear suspension to spec and I have an adjustable rear trac-bar like seen from Porterbuilt or No Limit

Does anyone know the correct torque specs for the bolts/studs that go thru the trac bar ends (heim joints) ??

I'm a notorious over tightener and the assembly manual seems high at 135 ft/lbs if I am reading it right.

Don't want to bind anything or limit travel

Typically the torque spec will be directly related to the bolt size and grade. Do you know what size the bolt is, and what grade it is?

Nate - I'm going off memory from last night but I believe this is correct

Upper Bolt: Grade 5 - 1 1/8"
Lower Bolt: Grade 8 - 15/16"

You will go off the actual diameter of the bolt... not the size of the wrench you use on the head. Google torque specs on the size and grade bolt you have (after confirming when you get home). There may be a slight variance in the spec sheets you find, but you will notice that they will typically all be within 5 lbs or so from eachother.

Thanks Nate - Always learning

Looks like 100+ft/lbs might not be that far out of line

Nate - just out of curiosity and completely understanding your information will not apply to my specific application

What would you recommend to someone torquing the bolts holding the trac-bar in your kit to?

Just want to see if I am in the ball-park and not way out of line when i cross-reference my diameter later
