Product Details

The Cometic C4323-051 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Nissan RB30 engines. This precision-manufactured gasket features an 87mm bore diameter and 0.051-inch thickness, designed to provide exceptional sealing performance under extreme conditions.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior durability and heat resistance
  • 87mm bore diameter optimized for RB30 engine applications
  • 0.051-inch (1.3mm) compressed thickness for precise compression ratio tuning
  • Advanced embossment technology ensures optimal sealing at combustion chamber, coolant, and oil passages
  • Resists blowout and maintains seal integrity under high boost and extreme cylinder pressures
  • Eliminates the need for additional sealants when properly installed

Cometic MLS head gaskets are the preferred choice for performance and racing applications where reliability is critical. The multiple layers of stainless steel with an elastomeric coating conform to minor surface imperfections while maintaining excellent recovery properties. Ideal for turbocharged, supercharged, and high-compression naturally aspirated RB30 builds.

Part found, hopefully ships quickly, thanks

Had problems with the paypal checkout. It kept adding more quantity of the item i was ordering. The product did not fit and had to be modified to fit the new slave cylinder,the end was a few thousands to big. Other than that the product was complete with all the pieces to install it and now works great.

super easy order & pay

Just order the 1108 turn over ball for 2010 Super Duty and received it within (5) days. Just can't wait to put it on and start pulling the trailer with my new diessel.

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere
