Class 10.9 (grade 8 equivilent) Exhaust manifold bolt/washer kit. Stronger than OEM!

[yudkib]

Ive got a big pile of these bolts and have no use for them. Dont be fooled by people saying you can buy grade 8 bolts at lowes or ACE, you cant. you can buy class 8 but thats metric grade 5 equivalent. these are the real deal - class 10.9.

one "kit" will include 8 bolts and 8 matching lockwashers.
some notes: these are flanged bolts, OEM is cap head only. thus they are wider at the base of the head. they are also 13mm heads instead of 12. when i installed my aftermarket mani, i had to re-use one of the OEM bolts since i didnt have a 13mm wrench that would fit. your mileage may vary.

and when installing these, for the love of god, use copper anti-seize, and follow the torquing pattern.

$8 shipped per "kit"
PM or post if interested. Tracking is not included and is an extra dollar if interested.

quick comparison -
OEM (class 8.8) - 120 ksi ultimate strength
this kit (class 10.9) - 150 ksi ultimate strength
ARP - 170 ksi ultimate strength

this is your chance to get bolts that are 11% weaker than ARP, and 90% cheaper. thats quite a swing.

Are these same length as stock?

 

[yudkib]

ill grab a comparison shot - theyre within about 1-2mm if i recall... extremely close.

 

[yudkib]

ok so the OEM bolts are about 1mm longer at most, but due to the nose on the bolts, the thread length on these is actually longer.

 

[KrayzieFox]

Are they still 12mm?

 

[yudkib]

the heads? no... as specified in the OP
theyre 13mm, so you might have trouble squeezing a wrench into some of those hard-to-reach places. i know i reused just one of my OEM bolts when i did my wagner mani install.

hmm, I think I may try and fit them with the hiboost mani, it's quite solid (aka heavy)

any chance of sets for intake mani too?

 

[slavrenz]

Good luck with the sale, man. You may not be able to buy class 10.9 bolts at Lowe's or ACE, but any auto parts store carries them.

 

[yudkib]

they may have them in the back, but individual bolts from them are generally crazy expensive. if i remember, i asked about these and they said they were $2.29 each. NPT fittings from them are like $3 each... its absurd.
