New Severe Duty 

High Performance Diesel Ring Sets

Top and 2nd rings are crafted from Martenstic Ductile Iron, the highest strength iron available, specially heat treated and coated with CrN (Chromium Nitride is a chemical compound of chromium and nitrogen with the formula CrN. It is very hard, and is extremely resistant to corrosion) for lasting durability and reduced wear.

Oil Ring – Two different oil ring configurations, Nitride Steel with chrome face, or Iron with chrome face, depending on the specific application and use are provided. Both are longer lasting, provide better sealing, maximum performance, lowers oil temperature, and maintains cleaner, longer lasting oil.

While supplies last, select application Diamond Finish rings are on sale for a low price of just $39.95 per ring. Now you can gain horsepower, for less, and still benefit from the Improved sealing between piston and piston ring that Diamond Finish provides. You will have to utilize custom pistons for these applications. Please choose carefully as there are no returns or refunds on these purchases.
