Fel-Pro Cylinder Head Gasket for Ram 1500 2011–2024 (26423 PT) — MLS with NEXTGEN Coating

Fel‑Pro 26423 PT is a multi‑layer steel cylinder head gasket engineered to restore a reliable combustion seal for compatible Chrysler, Dodge, Jeep and Ram engines from 2009–2024.

This Fel‑Pro cylinder head gasket is built for professional repair environments where sealing surfaces may be imperfect and engine temperatures are high. Its multi‑layer steel (MLS) construction, LaserWeld stopper layer and NEXTGEN coating work together to resist head lift, reduce blowout risk and provide consistent sealing across the combustion chamber and coolant/oil passages.

How does this gasket stand up to higher engine temperatures and surface wear?

The 26423 PT uses Fel‑Pro’s NEXTGEN coating that is applied in precise amounts to tolerate elevated cylinder head temperatures and mating surface finishes up to 80 Ra. This coating helps maintain adhesion under thermal cycling and reduces the chance of leaks over time.

• NEXTGEN coating optimized for high‑temperature durability
• Coating tolerates rough surfaces up to 80 Ra
• Consistent application prevents uneven sealing

What features reduce the risk of combustion blowout?

The gasket incorporates an exclusive LaserWeld stopper layer that reinforces critical combustion areas to resist deformation and blowout. In combination with embossed sealing beads and the MLS construction, it preserves a robust combustion seal even under elevated cylinder pressures.

• LaserWeld stopper layer protects vital combustion zones
• Embossed sealing beads eliminate common leak paths
• Multi‑layer stainless steel maintains sealing stress during head lift

Will this gasket fit my vehicle and what should I check before buying?

The 26423 PT fits a wide range of Chrysler, Dodge, Jeep and Ram model years listed by Fel‑Pro, including Ram 1500 through 2024. Always confirm fitment by entering year, make, model, engine and trim into the vehicle compatibility tool and review any qualifier notes before purchase.

• Compatibility includes many 2009–2024 Chrysler/Dodge/Jeep/Ram models
• Use the vehicle fitment tool and read any blue “i” qualifier notes
• Verify engine code and trim to avoid returns

How does the design handle imperfect sealing surfaces during repair?

Fel‑Pro designed this gasket specifically for the repair environment where heads and blocks may not be factory‑flat. The combination of MLS layers, embossed beads and NEXTGEN coating helps bridge minor surface irregularities and maintain a long‑lasting seal.

• Engineered for repair‑grade surface conditions
• Embossed beads concentrate sealing where needed
• MLS construction compensates for head lift and surface variance
