Common questions
How many gaskets do I need for my V-twin engine?
You'll need one gasket per rocker box base. Most V-twin engines have two rocker boxes (one per cylinder head), so you will typically need two gaskets for a complete job.
Is this a direct OEM replacement part?
Yes — Harddrive manufactures this to OEM specifications as a direct replacement for stock rocker box base gaskets, ensuring proper fit and function.
Do I need any special tools to install this gasket?
Basic hand tools and a gasket scraper are generally sufficient for installation. Always refer to your engine's service manual for specific torque specifications and procedures.
