The difference between ARP studs and the L19 studs is quite evident when you install them. With the ARPs there is a little give (stretch) going to the final torque. With the L19 studs it is just a solid stop.

Just an FYI, you can get ARP studs or L19 studs from A-1 Technologies.

^ how do you go about ordering a set of L19s from A1?

 

I just simply called them and bought them.

 

That's easy - thought we had to provide specifics of stud dimensions, pitch, length, etc.

How much were they?

 

They had all the measurements beings they make them for FBM and for MCP. This was about 2 years ago, but I believe they were a bit over 220ish.

I bought mine through redboost10 on here. When he put in the order, we ordered 3 sets total. From what I remember, they tend to like to make them in batches.
