Crower Rocker part number.
 

What is the part number for the Crower roller rocker for a 525??

Thanks

73605-16

So what is the difference between the Comp Pro Magnum and the Crower Enduro SS rockers?? Other than about a hundred bucks...

When you change rockers on a 525, you MUST reuse the polylocks from the OEM rockers as they are the only ones that are short enough to clear the valve covers. The comp pro magnum rockers have a narrower area around the fulcrum which requires the use of their polylocks which are a smaller diameter so the OEM polylocks will not fit. The Crowers are more expensive, but they are very solid pieces..

Also, it looks to me that the down angle on the roller tip of the comps is sharper than the crower which may cause an issue with clearance over the retainer.

You can't go wrong with the Crowers.. They're more expensive, but they will last a long time and hold up to the stress of the 525 valve train..
