With advances in automobile technology, higher quality and dramatically higher performance is required for most automobile components. Probe gas-nitrided steel piston rings have proven to be a high quality product, based on innovative product, material and coatings.

Traditionally, pre-gapped replacement ring-sets are “sized” for the nominal bore size of the engine, usually with generous end gap clearances to minimize the potential of butting the end gaps. These are perfect of the novice engine builder or for a lower performance build where ring end gaps are not critical. more info
