Frequently Asked Questions
Will this fit my Twin Cam Harley?
No — this bushing is for EVO-era engines only (1984–1999). Twin Cam models require a different part number.
What is SAE 660 bearing bronze?
A high-load bearing material that resists deformation and friction under high RPM, engineered for rocker arm durability.
Do I need to replace both rocker bushings at once?
It's recommended to replace both left and right bushings during a valve train service to maintain consistent rocker arm function.
Is installation difficult?
The tapered lead on each end eases installation into the rocker arm bore. Use the appropriate bushing press or bearing driver tool for best results.
