GeeZ Posted May 19, 2016 Share Posted May 19, 2016 Northern Auto Parts is selling new rockers for $9.89 each. MSA $400 for 12. Quote Link to comment Share on other sites More sharing options...
ryant67 Posted May 19, 2016 Share Posted May 19, 2016 (edited) There is a reason for the price difference. MSA is selling OEM Nissan rocker arms, whereas Northern is selling ITM brand. The Nissan ones are likely superior in terms of metallurgy, and they are also NLA, so they command a premium when it comes to price. Good heads up though, could save some folks who are on a budget some money! (Edited to retract a misleading statement...)

Leon Posted May 19, 2016 Share Posted May 19, 2016 There is a reason for the price difference. MSA is selling OEM Nissan rocker arms, whereas Northern is selling ITM brand. The Nissan ones are FAR superior in terms of metallurgy, and they are also NLA, so they command a premium when it comes to price. Cheaper rocker arms will wear quicker and potentially cause damage to the camshaft in the process. Good heads up though, could save some folks who are on a budget some money! I'm curious, do you have any examples of this? Quote Link to comment Share on other sites More sharing options...
ryant67 Posted May 19, 2016 Share Posted May 19, 2016 Suspected I would get called on that statement. I'm 95% sure I read it in a couple of threads on here, from reliable posters - but just to make sure I'm not talking out of my ass, I'll see if I can dig them up. If not, I'll gladly retract, but there are reasons the OEM rockers are more desirable, no? Quote Link to comment Share on other sites More sharing options...
ryant67 Posted May 19, 2016 Share Posted May 19, 2016 Didn't come up with much. Post #6 here (http://forums.hybridz.org/topic/119576-rocker-arms-state-of-the-situation/) touches on someone with not-so-great experiences with aftermarket rocker arms, but I couldn't see much else. I suspect I was confusing the rockers arms situation with the cwc camshaft issue. My mistake. Quote Link to comment Share on other sites More sharing options...
Leon Posted May 19, 2016 Share Posted May 19, 2016 I'm currently running a mix of Sealed Power and Nissan rockers in my motor and frankly I can't say that one is much better quality than the other. Time will tell I suppose. I don't have any experience with the ITM parts but I suspect they'll be fine given care is taken in setup and break-in.

GeeZ Posted June 7, 2016 Author Share Posted June 7, 2016 Can someone post the part number for the Nissan rockers so I can prove to myself that they are NLA. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
