Yes I've installed them on a 3L over a year ago. the main thing to reference is if they are made for the 2.5 spec then they will be very slightly shorter which only means that there will be a small error in calculating the compression ratio. However if you have a 3L spec rod length and use it in the 2.5 then you have just decreased the piston to valve clearance which is very minimal anyways. What does Pauter say the center to center measurement of their rod is?
