FAQ

Will this gasket fit my 1989–1998 5.9L 12-Valve RAM? Yes — this is the OEM head gasket for 1989–1998 Dodge Ram 2500/3500 with the 5.9L 12-Valve Cummins. Always verify by VIN/ESN before ordering.

Is this the standard-thickness gasket? Yes — 3283335 is the standard-thickness (stock deck height / piston protrusion) gasket. Do not use if your engine is decked or modified — in that case, check oversize options.

Should I use head studs or new bolts when reinstalling the head? For stock or lightly modified engines, new OE bolts are acceptable. For higher boost or increased horsepower builds, many builders prefer high-strength head studs for more consistent clamp load.

Can I reuse my old head gasket? No — head gaskets are single-use. Always install a new gasket whenever the head is removed.

What else should I replace when doing a head-gasket job? It’s wise to install a full upper-engine gasket set, inspect or replace head bolts/studs, check head/block surface flatness and surface finish (RA), and replace any worn or questionable components (valves, seals, coolant, oil, etc.).
