12 ValveBillet Side Tappet Cover fits Cummins

Item #: 120510-2 | Tappet Side Covers

Fits 1989 to 2002 12 Valve and 24 Valve 5.9L Cummins engines. 24 Valve engines have to be converted to a p-pump to use this cover. Will not fit VP44 equipped engine, but we now have one that will fit VP44 equipped engines. Billet side cover includes o-ring to seal against block and stainless hardware. Starts out as 3/4" thick material then fully CNC machined in house. Will not fit common rail engines. Now comes with baffling built in. Breather ports use -12AN male o-ring boss fittings. Also has clearance machined in for roller lifter clearance for engine utilizing roller lifters. Because of the variety of roller lifter systems being used customer needs to verify clearance on his engine. This fits the most of the roller lifters being used.
