Fel-Pro Engine Cylinder Head Gasket for Ram 1500 (2011–2024) — MLS, NextGen Coating

Fel‑Pro 26423 PT is a multi‑layer steel cylinder head gasket engineered to restore a durable combustion seal for compatible 2011–2024 Ram 1500 and other FCA vehicles.

This head gasket is built for professional repair environments where surface imperfections, higher operating temperatures, and cylinder head movement are common. Fel‑Pro uses layered stainless steel, a LaserWeld stopper layer, and a NextGen coating to maintain sealing stress and resist blowout, helping you refinish an engine with a factory‑grade fit. The gasket’s embossed sealing beads and tailored materials focus on eliminating leak paths while accommodating rougher sealing surfaces typically encountered during rebuilds.

Will this Fel‑Pro gasket fit my Ram 1500?

It fits a wide range of Ram 1500 model years and many related Chrysler, Dodge and Jeep applications listed by Fel‑Pro. Before ordering, verify year, make, model, engine and trim with the seller’s fitment tool to confirm compatibility and review any qualifier notes.

• Compatible with 2011–2024 Ram 1500 and several Ram 1500 Classic years
• Also fits select 2009–2023 Chrysler, Dodge and Jeep models as specified
• Use the online "Confirmed Fit" or vehicle selector to confirm fit

How does the gasket handle higher engine temperatures and rough surfaces?

Fel‑Pro applies proprietary NextGen coating in measured amounts to tolerate elevated temperatures and seal against surfaces up to 80 Ra roughness. The coating plus multi‑layer steel construction work together to preserve sealing clamping and reduce the risk of leaks under thermal stress.

• NextGen coating resists heat while promoting conformity
• Multiple stainless steel layers absorb head lift and retain clamp
• Embossed beads concentrate sealing at critical paths to prevent leaks

What prevents gasket blowout and improves combustion sealing?

The gasket uses an exclusive LaserWeld stopper layer that reinforces critical areas and limits damage from blowout. Combined with precise embossed sealing beads, this construction increases the gasket’s resistance to combustion pressure and helps maintain a consistent seal over time.

• LaserWeld stopper layer reduces risk of combustion blowout
• Embossed beads create focused sealing zones around cylinders and coolant passages
• Design aimed at withstanding repair‑level surface conditions

What should I check before installing this head gasket?

Confirm vehicle compatibility and any fitment notes, inspect cylinder head and block sealing surfaces, and verify torque specs and head flatness before installation. Proper prep and following manufacturer torque sequences help ensure the gasket performs as intended.

• Use the seller’s fitment check for year/make/model/engine/trim match
• Clean and inspect sealing surfaces; measure surface finish and flatness
• Follow engine manufacturer torque sequence and re‑torque recommendations

Who is this for: The Fel‑Pro 26423 PT head gasket is aimed at professional mechanics, experienced DIYers and rebuild shops working on late‑model Ram 1500 trucks and related Chrysler/Dodge/Jeep engines that require a reliable, repair‑grade replacement. It’s a suitable choice when you need a multi‑layer steel gasket designed to tolerate imperfect sealing surfaces, higher temperatures and engine movement while restoring combustion sealing performance.
