Hey guys just hoping someone can give me the bolt size, thread, pitch etc of the exhaust manifold bolts. Away from my truck at the moment and just getting parts together for the weekend.

Thanks, eric

 

10mm, but I'm not sure of the thread pitch

fine thread?

 

m10 1.25

 

Can't say I understand bolt terminology that great. Just to confirm, if I visit a bolt shop and ask for M10 1.25 nuts they will know what I am talking about.

 

yuppers.
Well, really you should say something like "Metric size 10 with 1.25 thread pitch"

 

You should get those at the stealership. Exhaust hardware is made of special alloys that deal with high temps in the right way, esp. expanding at the right rate so they don't come loose.

 

Just ordered these myself from trdparts4u

Qty 8 exhaust stud nuts (90179-10052)
Qty 4 Upper studs (90116-10067)
Qty 4 lower studs (90116-10064)

The upper and lower are different lengths, and the nuts have apparently been superseded by 90179-10175.
