About the ER Coilover


*ER Series Coilovers now come digressively valved similar to the DS series as standard. If you would like linear valving, please get in touch to make a custom order.

Fine tune your vehicle with absolute adjustability using our ER Type system. It features large external reserviors front and rear, separate rebound and compression adjustment, and a twin-piston design. The external reservoirs hold much more oil than conventional coilovers allowing the unit to operate for much longer before overheating. Additionally, the external reservoirs house the secondary piston which allows for adjustment of compression. This is the perfect coilover for the person who wants to fine-tune their setup using the separate 30-way rebound and compression tuning dials.

  • 30 levels of separate rebound and compression adjustment
  • Dual Piston Design (1 in res., 1 in shock)
  • Custom spring rates available
  • 1 year manufacturer warranty
