Cometic Gasket Chrysler 6.2L Hellcat Gen-3 Hemi .071in DST Cyl. Head Gasket - 4.150in Bore - LHS Fits 2015-2019 Dodge Challenger SRT Hellcat Models and Charger SRT Hellcat

This Cometic cylinder head gasket delivers precise sealing for the left-hand side of Chrysler 6.2L Hellcat Gen-3 Hemi engines with 4.150in bores. It fits 2015-2019 Dodge Challenger SRT Hellcat, Demon, Redeye, Widebody variants, and Charger SRT Hellcat models. The .071in thick MLS design handles extreme boost and compression in performance builds while maintaining stock-like fitment.

Key Features

  • Multi-Layer Steel (MLS) Construction: Provides robust sealing against high cylinder pressures and temperatures common in supercharged Hellcat engines
  • Direct Seal Technology (DST): Pressure-bonded layers eliminate need for sealants, ensuring clean installation and consistent performance
  • 4.150in Bore Sizing: Matches stock and stroker Hellcat bores for optimal combustion chamber alignment and fire ring placement
  • .071in Compressed Thickness: Maintains desired compression ratios in high-performance setups without milling heads excessively
  • LHS Design: Specific to left cylinder head, sold individually for targeted replacements or engine builds

Product Notes

  • Inspect cylinder heads and block surfaces for flatness before installation. MLS gaskets demand mirror-like finishes
  • No additional gasket sealant or spray required due to DST bonding
  • Packaged flat in protective envelope. store horizontally to avoid bending

Installation Notes

  • Professional installation recommended.
  • Torque head bolts to OEM specifications in sequence. re-torque after initial heat cycles
  • Compatible with stock Hellcat heads and ARP head studs. no modifications needed
