First off let me say that I do not go out , and decide that today I will give a product a poor quality rating. Being that we do sell many roller rockers in the course of a year. How many ,.. I would say that in a year we sell 150-175 sets. SO we would see more issues with a certain product than the next shops that uses' or sells 15 sets in a year. Some are sold as a rocker kit only and others are in our performance package kits. Most are sold in kits. So I know what lift cams, valve spring seat pressures, etc.
Being that we are a shop and after installing some of these other brands and having to replace them for free. We may have become a bit gun shy, for a very valid reason. The SE units are made by Jim's, we have seen cracking in those, the pushrod socket area being soft came from , ultima, and tp. Now these two products when in hand look like the same style casting, there are small changes in the bushings but casting wise they look like the same place is making them. I have heard both ways yes and no. In the end it does not matter, if the part is failing then it is time to make sure we no longer sell it.
And we are not the only ones that have had issues with other brands. As I made some calls when I had failures, and you get a answer like" yes we have seen that on several sets. TP will replace that bad unit" I have to say again they did take care of a few issues. Now Ultima refused to replace them at all. basic statement used part no warranty. Yea I know, does not make any sense. What can you do. The S&S forged unit is a very nice rocker and in most cases does not require much if any rocker box lid clearancing, so that is a plus.
On a side not any time you are working with the valve train and you have the rocker support plates off. Do a quick end play check on the rocker to plate. Have been seeing a few plates on the new models that are a bit too large. That is a great way to have a ticky valve train. Hope everyone has a great day.
