Features & Benefits:
* Sold as a Pack (8).
Tech Tips:
* In November of 2014, S&S switched to powder metal valve guides.
(They take a larger seal = SS900-0737).
* The old style cast iron guides use this smaller seal set.
* The best way to get the correct guides & seals would be using the serial number on the head, It is stamped into the head near the exhaust port or if the customer takes a look at the valve guide.
* This SS90-2158 guide seal is for u se with S&S cast iron valve guides
* Use SS900-0737 guide seals if your head utilises Powder Metal Guides
* View spec sheet attached for further details.
