Fel-Pro MLS Cylinder Head Gasket for Ram 1500 2011-2024 — 26423 PT, NextGen coating & LaserWeld stopper

The FEL-PRO 26423 PT is a multi-layer steel cylinder head gasket engineered to restore and maintain a durable combustion seal for 2011–2024 Ram 1500 engines.

Fel-Pro designs vehicle-specific gaskets using materials and coatings chosen to match repair conditions and modern engine demands. The 26423 PT combines a NextGen coating, LaserWeld stopper layer, and embossed sealing beads to tolerate uneven sealing surfaces and higher temperatures common in repair environments.

How does this gasket resist blowout and combustion leaks?

The 26423 PT uses a LaserWeld stopper layer and precise embossed beads that concentrate sealing force where combustion pressures are highest. Together with multi-layer stainless steel construction, these features reduce the chance of burn-through and maintain compression under thermal cycling.

• LaserWeld stopper layer to reduce gasket damage from combustion pressure
• Embossed sealing beads at critical ports to close potential leak paths
• Multi-layer steel (MLS) construction to sustain sealing stress and head lift

Will this part fit my Ram 1500 or related vehicles?

This gasket is listed for a broad range of Chrysler, Dodge, Jeep and Ram applications, including 2011–2024 Ram 1500 and many related model years. Always verify fit using your vehicle year, make, model, engine and trim and check any qualifier notes shown in the vendor fitment tool.

• Compatible with select Ram 1500, Ram 2500/3500, Jeep Grand Cherokee, Dodge Charger/Challenger and others
• Check the seller’s Confirmed Fit tool and hover over any information icons for notes
• Verify engine code and trim to avoid ordering the wrong gasket

What materials and coating features improve durability?

Fel-Pro applied a proprietary NextGen coating in precise amounts to handle higher operating temperatures and rough cylinder head finishes up to 80 Ra. The combination of coating, layered stainless steel, and embossed beads creates a robust barrier against fluid and gas leaks even on imperfect mating surfaces.

• NextGen coating designed for higher temperature durability
• Stainless steel multi-layer construction resists fatigue and head lift
• Engineered for repair environments with imperfect sealing surfaces

How should I confirm and install the gasket for best results?

Confirm fitment with your vehicle details and any seller notes before purchase. For installation, prepare the head and block surfaces per manufacturer specs, torque to the engine maker’s sequence and values, and replace any related components as recommended to ensure a reliable seal.

• Verify fitment with vehicle year, engine, and trim using the vendor tool
• Clean and inspect head/block surfaces; follow OEM torque sequence
• Replace head bolts/studs and associated seals as required for a proper repair

Who is this product for? The FEL-PRO 26423 PT is aimed at professional mechanics, weekend DIYers, and repair shops tackling head gasket replacement on Ram 1500 engines and compatible Chrysler, Dodge, and Jeep models. It suits anyone needing a purpose-built, repair-grade MLS gasket with coating and stopper-layer technology to handle imperfect surfaces, higher temperatures, and the demands of repeated thermal cycles.
