Is there a way to check and see if I have 1.5 roller rockers vs 1.6? I can't remember what I bought years ago.

Most aftermarket ones have the ratio stamped on the body of the rocker

What rocker do you have? Post a pic if you can.

They are Pro Form RR (I know there are better RR dont need opinions on others) in the pictures the ones I ordered about 8 yrs ago are on the left (1.5 is what I ordered then) the RR on the right is one I ordered the other day (1.6) just wondering how I can tell them apart I see no physical difference in them at all. Im wondering if I got 1.6 RR by mistake 8yrs ago.

Only way to really tell, I guess, is to measure center fulcrum to center roller and post it on here. Then maybe someone with a known ratio, can mesure theirs and respond back.

The ratio is changed by moving the pushrod cup closer to the rocker arm fulcrum on 1.6 rr. In your last pic you can see the difference, Left 1.5, right 1.6

I have a 1.6 proform rocker lying around that I can measure for you to compare with when I get home tonight.

So Guppymech these look correct to you? left being 1.5 and right being 1.6 I'm not sure what it is to look for. Thanks Puck that would be great.

measure the fulcrum, the the hole in the middle (the stud the rocker sits on)... to the end where the pushrod cup is... I am fairly certain you will have different numbers.

Looking at the pictures all I can say for sure is the rocker arm on the right has a higher ratio than the one on the left. You say you're not sure what to look for, the rocker arm with the higher ratio has the pushrod cup closer to the pivot of the rocker arm.

If what they are saying is true then yes.

Center of the fulcrum to the center of the pushrod cup, not the end of the body.

The body on the right is shorter, from the table up to the fulcrum, than the one on the left so you have to measure to the pushrod cup..

I'm new here and scanning all the posts here. I wasn't thinking to see how old this one was before responding.
