This is the extended J-bolt only for the SuperTrapp 3S Series Resonator, Part No. ST-3S-5500. The resonator includes this long bolt, but replacements are available if yours gets damaged or goes missing. Sold individually; includes washer and nut.
This bolt is only used when the muffler has the resonator installed. We also offer the SuperTrapp Standard J-Bolt for 3S Series (Part No. ST-3S-7363), for use without the resonator. New mufflers include the standard bolt.
