Main Bearing Gasket Set 04-21 Hemi 5.7L

The Main Bearing Gasket Set 04-21 Hemi 5.7L by MAHLE ORIGINAL/CLEVITE is a critical engine sealing component engineered for Dodge, Jeep, and Chrysler vehicles equipped with the legendary Hemi 5.7-liter V8. This gasket set addresses one of the most common maintenance intervals in high-mileage Hemi engines, preventing oil leakage at the main bearing saddle interface where crankshaft journals meet the block. Whether you're rebuilding a engine, addressing seepage after 100,000+ miles, or performing preventive maintenance on a newer platform, this OEM-spec gasket set is essential for restoring complete engine block sealing integrity.

Manufactured by CLEVITE, a Mahle subsidiary with decades of OEM gasket engineering, this set uses precision-molded elastomer and composites designed to withstand the Hemi's high compression pressures and thermal cycling. The main bearing gasket set specifically seals the critical interfaces between the crankcase and bearing caps, preventing pressurized oil migration into the pan and combustion areas. Each gasket maintains dimensional stability under continuous operation, resisting oil degradation and thermal stress that would compromise aftermarket alternatives. The JV1720 specification ensures exact fitment across 2004–2021 5.7L Hemi platforms, with gasket thicknesses and material compounds validated for both naturally aspirated and supercharged applications.

Professional mechanics and Hemi enthusiasts performing full engine rebuilds, main bearing replacement, or block resurfacing rely on this gasket set to ensure leak-free operation post-assembly. Installation requires proper bearing cap torque sequencing and gasket bed preparation, making it ideal for DIY rebuilds or professional shop work. This set is fully compatible with all 04-21 5.7L Hemi variants across Ram trucks, Dodge Chargers, Challengers, and Jeep Wranglers. At 1.325 lbs and compact dimensions, the gasket set integrates seamlessly into any engine assembly workflow, delivering OEM reliability without premium pricing.
