4065 are non roller. Can't find 1065.

It may be possible that "1065" was a number for a 1 indivual rocker arm. The lifters are numbered similaraly. You used to be able to buy 1 as needed. Now they are only sold in sets of 4. same lifter just changed the part # number. Call S&S tech they'll hook you up

Thanks guys and thanks Lee for the link to the catalog. I am in the process of gathering parts to do a swap over to the S&S rocker boxes.

Just a little free advice, you may want to pull your heads and have the valve guides checked. The TP rockers in some cases have caused some unusual valve train wear and since your going to all the trouble of replacing the rockers and rocker boxes the heads are the next item down. Both of my heads we're replaced by BDM under warranty for that very reason.....
Good Luck & Peace Out

Hey RRRuff I have an 05 and I recently changed my rocker boxes. I already had roller rocker arms and I didn't change them - just something worth pointing out because they are expensive. Some will probably say change them and others will think there's no point. Just something for you to think about.

Got the new S&S rocker arms today. The guy I bought them from had sent me an email saying they were part number 90-1065 but actually they are 90-4065 which is what they should be. So I have just about gathered the parts I need to change over to the S&S.
