Ring Set, Piston (std) for 90~95 ZR-1 LT5.  Sold as a COMPLETE engine set of standard bore size of 3.900" piston rings, with OE pistons.  

 Manufactured for Jerrys Gaskets by Total Seal.  This ring set is uniquely applicable to the ZR-1 DOHC 32Valve LT5 engine. Designed to be compatible with the nikasil liners.  

 NOTE: These rings are "file to fit" and require end gap adjustment, which is the customer's responsibility.  Rings should be fitted to each cylinder and the end gap adjusted as required for customers intended use. Rings were manufactured for minimal filing/grinding to attain the desired end gap for the stock bore size.
