RACE ENGINEERING RING SETS.....
We stock premium file-fit rings, popular 1/16" and super low friction Metric series. Our metrics are available in 1.2 x 1.5 x 3mm and the new Pro-Series with 1.0 x 1.5 x 2mm, the thinnest you can get.
2-Ring sets are available from Wiseco (click back button and see Wiseco listing).
TECH: 1mm = .039", 1.2mm = .047", 1.5mm = .059", 2mm = .079", 3mm = .118". Normally, pistons for these engine are 1/16" (.062") top & 2nd. with 3/16" oils (.188"), so you can see how much thinner our metrics are. Their reduced radial dimension creates less friction and allows the face of the ring to better conform to the cylinder wall for enhanced ring seal.
Race Engineering rings are listed by diameter: 3.815 = +.030", 3.825 = +.040".
