Our works high flow linear shock pistons are on another level compared to the stock and aftermarket units that are available. machined from 7075 alloy, symmetrical tri orifice facing with large port area vastly improves response and sensitivity. Sharp edge cnc port machining allows precise flow and consistent, repeatable performance. Flat precicsion faces allow for zero preload on the shims but allows the use of ring shims. Exclusive fcr works piston band is vastly superior to stock and aftermarket. Allowing ultra slippery, very low friction, perfect oil retention, solid piston to shock body seal for zero blow by and very reliable. Comes with a high performance piston band oring for the perfect amount of preload.
