Description

Interstate-McBee M-3283335 Head Gasket – 89–98 5.9L Cummins 12-Valve (Standard Thickness)

OEM-style standard thickness head gasket engineered for the 1989–1998 Dodge Ram 2500/3500 5.9L Cummins 12-valve (6BT). Built to factory dimensions for reliable sealing and long service life on stock or mildly upgraded engines.

  • Direct replacement: Matches Cummins 3283335 (standard thickness) specifications.
  • Precision construction: Robust fire-ring and coolant/oil passage geometry for consistent clamp load.
  • Aftermarket value: Interstate-McBee quality at a lower cost than OEM boxed parts.
  • Right application: Designed for 12-valve (1989–1998) — not for 1998.5–2002 24-valve ISB.

Vehicle Fitment

Always confirm by engine serial number (ESN) for best results.

  • Dodge Ram 2500/3500, 5.9L Cummins 12-valve

Installation Tips

  • Use new head bolts or quality studs; follow the Cummins torque and angle sequence exactly.
  • Re-torque/heat-cycle only if specified by your fastener manufacturer.

FAQ

Is this the correct gasket for my 1996 5.9L 12-valve?
Yes. M-3283335 (STD) fits 1989–1998 12-valve 5.9L Cummins applications when standard thickness is specified.
What if my head/block was milled?
If material has been removed, consider oversize thickness options (e.g., 3283337 +0.25 mm or 3283339 +0.50 mm). Measure piston protrusion and follow Cummins guidance.
Will this work on a 24-valve (1998.5–2002)?
No. This SKU is for 12-valve 6BT (’89–’98). Use the proper 24V ISB head gasket for 1998.5–2002 applications.
Do I need new head bolts/studs?
Highly recommended. Stock torque-to-yield bolts should not be reused. Studs improve clamp consistency, especially on tuned engines.
