Wiseco Sport compact kits include the high quality NPR XX rings, which are the best quality steel nitrided top rings and napier style 2nd rings.  It's become common practice to pair these rings with the Supertech pistons for a better quality seat that is known to reduce blowby and oil consumption. 


These are compatible with our NC Duratec and Wiseco Rings
