CATERPILLAR 3406E STAGE 1 Long Block Engine




We have taken our years of vast knowledge of High horsepower light duty diesel truck engines and applied them to the caterpillar heavy duty engines for a long lasting reliable Power Combination. Our Stage 1 Caterpillar  3406E 1 Long Blocks are built to last! High Quality Machining is one of the most crucial aspects of building long lasting Diesel Engine. Our Motto here is, ” If it’s Worth Doing it’s Worth Doing Right” .


This Caterpillar 3406E engine long block assembly contains a re-manufactured block assembled with all high quality top shelf new components.
All Cylinder blocks are Re machined to the utmost quality, Thermal cleaned, wet magna-fluxed and pressure tested. We do not counter bore blocks. New steel inserts are installed and machined in the upper and lower bores of the cylinder block for the correct fitment of the cylinder liners. The cylinder block deck surface is  then milled to a very fine RA Finnish for superior head gasket sealing. Main bores are checked and line bored with new Main bolts to correct any out of roundness in the main tunnel. Unlike most reman engines our engines are built to last and perform!!
