Frequently Asked Questions

What does MLS mean?

MLS stands for multi-layer steel — a construction that resists blowout and provides consistent sealing across repeated heat cycles.

Why is this sold in a 2-pack?

The 2-pack quantity is useful for shops and riders who service multiple bikes or want a spare gasket on hand.

Will this fit my Harley or Indian?

If your engine has a 4.000" bore, this gasket will fit. Verify your specific engine size before ordering — incorrect bore size will not seal.

Do I need new cylinder studs when I install this?

Reuse existing studs if they are in good condition. Always check stud condition and torque specs in your service manual before reassembly.
