Product Description
Genuine CUMMINS 5260648 OEM turbo to manifold gasket (T4i) for 2007.5–2012 Ram 6.7L Cummins. This multilayer steel turbocharger gasket seals the HE351VE/HE300VG turbo to the exhaust manifold so you don’t lose drive pressure, spool, or boost through a leaking flange. Ideal for stock turbo replacements, manifold swaps, or performance turbo upgrades that retain the factory T4i footprint.
Key Features
- OE Cummins 5260648 T4i turbo-to-manifold gasket for 6.7L ISB applications.
- Correct T4i flange pattern for HE351VE & HE300VG variable-geometry turbos.
- Designed as a single-use gasket – replace any time the turbo is removed.
- Helps maintain drive pressure, turbo efficiency, and exhaust system integrity.
- Compatible with stock or performance manifolds that retain the factory T4i footprint.

- Clean the turbo and manifold flanges until they are free of carbon, rust, and gasket residue.
- Inspect both sealing surfaces for warpage or damage before reassembly.
- Use the correct torque sequence and specifications for the turbo mounting hardware.
- After initial heat cycle, inspect for any signs of exhaust leakage around the flange.
FAQ
WILL THIS FIT MY 2007.5–2012 6.7L CUMMINS RAM?Yes. Cummins 5260648 is the OE turbo-to-exhaust manifold gasket for most 2007.5–2012 Ram 2500/3500 6.7L and 2008–2012 Ram 3500/4500/5500 Cab & Chassis trucks with the HE351VE/HE300VG turbocharger. Always confirm by VIN/ESN and turbo flange pattern before ordering.
IS THIS THE CORRECT T4I GASKET FOR HE351VE/HE300VG?
Yes. This gasket uses the factory T4i flange pattern used on HE351VE and HE300VG variable-geometry turbos found on 6.7L ISB Ram applications and many related ISB/QSB industrial engines.
CAN I REUSE THE OLD TURBO GASKET?
No. The turbo-to-manifold gasket is considered a single-use sealing component. Reusing an old gasket can lead to exhaust leaks, poor turbo response, and soot tracking at the flange. Always install a fresh Cummins 5260648 during turbo or manifold service.
WHAT HARDWARE SHOULD I REPLACE WITH THIS GASKET?
For best results, replace the turbo mounting studs with CUMMINS 4931642 OEM TURBOCHARGER MOUNTING STUDS and new turbo mounting nuts. Inspect the exhaust manifold and turbo flange for flatness at the same time.
IS THIS A GENUINE CUMMINS PART OR AFTERMARKET?
This listing is for a genuine Cummins 5260648 gasket sourced through CPP Diesel, not an aftermarket copy. Genuine Cummins gaskets are built to the correct thickness, material, and flange profile for long-term sealing performance.
