C.T.I. 31-099-01 Piston Rings For 2011-2020 Ford 6.7L Diesel Turbo Power Stroke V8

Brand: C.T.I. | Part Number: 31-099-01 | Bore: 99mm (STD)

Restore the compression, efficiency, and reliability of your Ford Power Stroke with this premium Piston Ring Set. Engineered specifically for the heavy-duty demands of the 2011-2020 Ford 6.7L Diesel Turbo engine, this set is built to withstand extreme thermal and mechanical loads.  

The top ring utilizes a double keystone design—a wedge-shaped, trapezoidal compression ring engineered specifically for high-load diesel applications. Both the top and bottom faces are tapered, which actively prevents the ring from sticking in the piston groove under intense heat and pressure, keeping your engine running smoothly under heavy towing and commercial use.
