Pretty simple part..Kinda hard to mess up ya know...Any name brand RAS will pretty much all be the same...Just go with Greddy,Tomei,P2M,Nismo,HKS...There all the same..P2M,And Greddy are the best priced though..

Dont think you really need them. Im starting to think RAS is just a gimic part. If the rocker is gonna come off, its because the lifter fails or shim comes off. The stoppers arent really gonna save anything. With good valve springs, you wont have a problem revving to 8krpm. I wouldnt push anything higher than that unless you run Solid lifters.

do not put a set of RAS on your engine. It is the worst idea possible..if the rocker pad comes off then it comes off. Just take off the valve cover find it and put it back on. I say this because RAS are hypocrites (sp) they really do not stop the rocker pads from coming off..not only do the rocker pads still come off with RAS but they break into many many pieces all throughout your head..RAS shatter rocker pads...now you have to buy a new rocker pad and find all of the pieces that broke off and hope that you got them all and some arent still laying somewhere in your head.

RASes will stop you from floating rockers, but they will not stop your rockers from breaking when they fall off of the lifters.

SR rocker breaking occurs when HLAs collapse, allowing the rocker to migrate and break in the fast moving valvetrain components.
