The ER Type coilover system features large external reservoirs front and rear, separate rebound and compression adjustment and a twin-piston design. The external reservoir holds more oil than conventional coilovers allowing the damper to operate longer before overheating. Additionally, the external reservoirs also house the secondary piston, which allows for adjustment of compression. This is the perfect coilover system for the person who wants to fine-tune their setup for serious track competition.
Dual piston design (1 in reservoir, 1 in shock)
Fully height adjustable shock body
