PROX Cylinder Sleeves Engine rebuilders find they can rely on the quality of PROX motorcycle sleeves. Cylinder sleeves are manufactured from centrifugally-spun Moly 2000 iron alloy castings, which insure ease of installation and trouble free boring. This boreable chrome-moly alloy contains alloys found in todays plated cylinders, but will never peel or flake. PROX’s Moly 2000 cylinder sleeves feature superior tensile strength, transfer heat quickly and efficiently, insuring a dependable long life engine.
