A-3802375-AI Gasket Set; Lower W/ Seals

One New Aftermarket Replacement Lower Engine Gasket Set with Seals for Cummins B-Series Engines

This lower engine gasket set covers the bottom-end sealing needs of the Cummins 4B, 4BT, and 4BTA 3.9L four-cylinder diesel engine. The kit includes oil pan gasket, timing cover and front cover seals, water pump interface gaskets, crankshaft seals, and other lower-end seals. It is a direct aftermarket replacement for OEM part number 3802375 and is used during engine rebuilds and overhauls to restore proper sealing across the lower engine assembly. Note: kit contents may vary by engine serial number (ESN) -- always verify your ESN before ordering. This kit supersedes earlier Cummins lower gasket sets 3802019 and 3802266 in many applications.
