Arp Tool!
 

What is the exact size / type of tool you need to install ARPS? I totally forgot and I don't have them with me. I'd like to pick one up ASAP before I go back to where my engine is.

I think its like a 12 or 14 allen head?

Re: Arp Tool!
 

12 mm 12 point allen sound right?

Re: Arp Tool!
 

I don't remember exactly, but I think its just a 6 point allen.

Re: Arp Tool!
 

I thought it was a 12 point 14mm and about a 8 or 10mm allen wrench.

Re: Arp Tool!
 

I use a 14mm 12pt deep socket.

Crescent wrench

Re: Arp Tool!
 

for 6bolts its a 14mm 12pt deep socket. I believe the allen is a 8mm, might be 6mm though.

Re: Arp Tool!
 

Oh, your talking about the nuts, I was thinking the little allen head in the top of the stud. The nuts are 12pt 14mm.

Re: Arp Tool!
 

The allen is a 5mm and the nuts are 12pt 14mm deep for sure

Re: Arp Tool!
 

positive on both 12pt 14 mil and 5 mm allen ?

Re: Arp Tool!
 

I have my block apart and confirmed them both.
