Machined from Wiseco sleeve forgings to offer the same toughness as Wiseco’s forged pistons. Designed for quick and easy installation of pistons without damaging the rings. These compressor sleeves are hard anodized and Teflon coated for low friction and prolonged wear resistance. These sleeves have a smooth radius that tapers down to the specific bore size to make installation of any piston a breeze. You will find that these sleeves compress the piston rings smoothly and evenly, greatly reducing the difficulty with installing thin high-performance oil rings. If you’ve ever broken or bent a ring, these high quality sleeves will be a lifesaver for your shop and come in a large range of sizes. Choose the size that corresponds to the finished bore size of the engine.   other sizes are available. if you need a size not listed get in touch and we can check availability and then add it to the website.
