5.9 cummins cracked block

If you're looking for solutions for your 5.9 Cummins engine's cracked block, you've probably seen the many forums online regarding the issue. You'll find that you're not the only one to experience this cracking problem. As many truck owners report, their Cummins block cracks began after merely standard operational use.

The experts at LOCK-N-STITCH Inc. noticed this issue, as they began to see more and more Cummins 5.9 engines built between 1999-2001 with cracks. Most common are those with a "53" cast on the lower front drivers side of the engine block. After extensive research, LNS's technicians realized that several factors were at work. Among them was a reduction in the iron's thickness at a section of the block below the core plugs, reduced coolant flow below this area of the block, and operation before the engine is fully warmed up. These circumstances often combine to crack a number of these Cummins engine blocks. LOCK-N-STITCH Inc. then set out to find a solution.
