COMETIC Replacement MLX Head Gasket — 4.125", 0.91 mm, Pair – 99-17 Dyna, 99-18 Touring, 00-17 CVO, 99-17 Softail

Upgrade sealing performance with the Replacement MLX Head Gasket. 🔧 Manufactured from premium fuel-resistant materials, this gasket resists creep, cracking and brittleness to maintain a reliable combustion seal under extreme conditions.

The folded center layer simulates an O-ringed head to concentrate torque at the combustion seal where it matters most. Proprietary high-temperature coatings and embossments create a micro seal against head and block surfaces to control fluid leakage. Ideal for Twin Cam applications using a turbo, high compression, nitrous or other power adders. Requires no special machining and installs like a regular MLS head gasket. Made in the USA. 🇺🇸

• High-temp coatings and embossments form a fluid micro seal at head and block interfaces.
