NW Sleeve

It's more important than you think and Northwest Sleeve has always used custom formulations that address the specific need of motorcycles, ATV's, snowmobiles and individual watercraft. It simply isn't enough to buy whatever the metals market has to provide at any given time. We take great care in working with our foundries to be confident that all standards are met so that we can be assured of the properties our sleeves will demonstrate: lubricity, hardness, oil retention, strength.
