Engine Parts

Competition Engine Parts for the 5.9L Cummins Diesel including girdles, lifters/tappets, high performance pistons, billet adjustable cam gears, high performance connecting rods, billet front timing covers, billet tappet covers, one piece billet valve covers, loaded cylinder heads, Waterman fuel pumps, competition cams, harmonic dampers, roller rockers and much more!

Please keep in mind when ordering parts:
All engine blocks 1997.5 & newer have "Encore" blocks. (these have 2 turbo oil return holes on the passenger side of the block)
They have 12mm main studs and must be drilled & tapped to 14mm x 2.00 to allow use of 14mm head studs.
89-97.0 Engine blocks have 14mm main bolts, so no modification is needed to use 14mm main studs.
All Cummins 5.9L engines 89-07 have 12mm head studs from the factory and require drilling & tapping to accept 14mm head studs.
