Default Gen IV Stock Rod Dimensions

Are gen IV stock rods 6.098 with .945 wrist pin?

Rebuilding the bottom end of my LQ4 and I know stock gen IV rods will be sufficient enough for the power levels I'm after but just need to make sure on the wrist pin size so I get the correct pistons.

Yes. They also have a floating wrist pin, not press fit like older Gen III's.

Yes sir. That's all I knew about them at first. Just needed to know the wrist pin size to make sure I get the right size pistons for the gen IV rods. Thanks!

A Gen IV bottom end will do exactly what you want...

That too. If I could come across an entire gen IV rod/piston assembly that would be cheaper and work just as good. Except it would need to be LQ9 pistons.

Funny, I'm looking at the same pistons.

What heads are you using? I'm using 243s.

Gen. 4 full floating rods use a .9431 pin. You can hone the Gen. 4 bushed rod for use with the .945 (.9449) pin.
