Wiseco’s 4.065 in ring compressor sleeve is a forged, precision tool made in the USA to ease installation of high‑performance piston rings. The hard‑anodized, Teflon‑coated sleeve features a tapered radius to smoothly compress rings into a specific bore size, reduces installation difficulty for oil rings, and is laser‑marked with the bore size for quick identification during engine assembly.
