ISX Cummins Cylinder Stiffener Plate - All ISX models

Reinforce Your Cummins ISX Engine with this Cylinder Block Stiffener Plate. When Cummins transitioned from a dual-cam to a single-cam system in the ISX engine, they also lightened the cylinder block. Unfortunately, this design change has led to recurring issues with liner instability and blown head gaskets, costly problems that impact reliability and performance.

Cylinder Block stiffeners are a proven solution in many engines by adding structural reinforcement to minimize flex and improve engine reliability and longevity.

✔ Reduces Cylinder Block Flex – Helps maintain liner stability and prevents premature wear.
✔ Prevents Head Gasket Failures – Keeps components aligned under high loads and extreme conditions.
✔ Proven Performance – Engineered, tested, and verified to work

Stop dealing with premature failures. This Cylinder Block Stiffener Plate is the upgrade your engine needs to handle heavy loads, high mileage, and extreme conditions.
