The 2.5 Performance Elite adds an external reservoir to separate shock oil from nitrogen, a larger 7\/8-inch shaft, a 2.5-inch body for increased oil capacity, and the DSC Dual Speed Compression Adjuster for terrain- and load-specific tuning. If the build sees varied terrain, load changes, or high-speed off-road use, the DSC adjuster earns its price.
