The ER series coilovers feature large external front and rear fluid reservoirs with separate adjustments for rebound and compressions. An advanced twin piston shock design separates the ER series from rest of the pack, with pistons in both the shock body and the external reservoir for pinpoint accuracy. The external reservoir system holds dampening fluid separate for the main assembly, allowing more precise and repeatable shock feedback without overheating. The large external reservoirs allows for a higher oil capacity that translates to faster heat dissipation during extended course use. The external resevoirs house the secondary piston, which allows for the independent adjustable of compression, separate from rebound adjustment.
