• Description:

  Rear Gear Housing. Inner Cover To Cylinder Block.

  This Genuine Mopar Timing Case Cover Gasket (68700302AA) is the high-integrity hydraulic barrier designed to maintain the absolute "zero-leak" performance of your engine’s timing assembly. While "universal" gaskets or budget-tier silicone "make-a-gaskets" often suffer from extrusion or chemical degradation—leading to unsightly oil weeping and dangerous pressure loss—this authentic OEM seal is engineered with proprietary elastomers built to survive the high-vibration environment of your front engine drive.

  The Advantage That Sets You Apart

  • Precision-Molded "Compression-Stop" Geometry: Unlike generic gaskets that can be "over-crushed" during installation—causing the seal to split—this Mopar gasket features integrated torque-limiters. This ensures 100% even clamping force across the entire timing cover flange, eliminating the "uneven-seal" leaks common with non-genuine alternatives.
  • Chemical-Grade Polymer Integrity: Formulated from a high-spec synthetic rubber that is chemically stabilized to resist the aggressive additives and pH shifts found in modern full-synthetic engine oils. It maintains its structural "memory" and sealing tension through thousands of miles of high-heat operation.
  • Thermal Fatigue Resilience: Engineered by the original manufacturer to handle massive temperature swings—from sub-zero winter starts to blistering operating heat. It resists the internal "honeycombing" and dry-rotting that causes unbranded rubber to become brittle and fail prematurely.
  • Hermetic "Dry-Seal" Surface Technology: Designed to provide a 100% airtight and oil-tight interface between your engine block and the timing case. This eliminates the "microscopic weeping" that leads to grime buildup and ensures your timing chain or gears stay perfectly lubricated.
  • High-Vibration "Stay-Flat" Architecture: Forged to match the exact topography of your vehicle's factory-stamped or cast timing cover. It maintains its rigid, functional shape during installation, preventing the "gasket-slip" or bunching that occurs with floppy, ill-fitting aftermarket seals.
  • Mopar Certified Protection: Backed by a Mopar Factory Warranty, offering a level of drivetrain-critical accountability and nationwide dealership support that online-only "white-label" gaskets simply cannot match.
