The EvoSpec Performance billet idler pulley is a great replacement for the OEM idler pulley. Our pulley is lighter then the OEM pulley, includes a higher quality high load bearing for additional RPM for those spinning their engines well past 8KRPM, and includes a spacer and a titanium bolt and washer mounting hardware.
Also what makes these pulleys far superior over OEM is the life time warranty on the bearing. If for any normal use conditions you have an issue they are 100% covered and serviceable.
