External Reservoirs for Increased Capacity
The clear-anodized aluminum bodies dissipate heat faster than conventional steel shock bodies. External reservoirs increase oil and nitrogen capacity, while race-developed high-flow pistons and application-specific valving help provide controlled, predictable damping.
The bolt-on package includes black-anodized reservoir mounting clamps and other components CNC-machined from 6061-T6 aluminum. Hard-chrome-plated, heat-treated alloy steel shafts, a redundant sealing system, and quiet nitrile rubber bushings support durability and suspension articulation.
