Idler Arm Bolts

[1993blazerlt]

What size are the bolts that hold the idler arm to the frame. Mine are so rusted that i can not tell the thread size. Are theses bolts grade 8?

I will have to check that for you give me some time to look it up(at work and do not have my books with me...in the garage)

If your replacing the Idler Arm the the kit should come with new bolts. If your just rplacing the bolts or some reason and arn't using factory bolts the do you need the thread size or the head size?

i am talking about the two blts that attach the idler arm to the frame the new arm only came with the bolts to attach to the center link

The bolts to the frame are re-usable.

not when you live in the midwest with a 11 year old rust bucket

Gotcha!

Well, the hex size is 18mm so that would make the bolt diameter 12mm. Pitch is probably 1.75mm.

About 2-1/2"
