HKS lists this part number only for factory 4WD manual transmission WGNC34 Stagea, so automatic and two wheel drive cars are outside the application. Upright monotube dampers are used at both ends with 30 steps of damping force adjustment, sprung at 10.0 kgf/mm front and 9.0 kgf/mm rear with helper springs at all four corners to carry the extra wagon mass. Full-length shock body adjustment gives 12 mm to 75 mm of front drop and 18 mm to 53 mm of rear drop against stock ride height. The WGNC34 Stagea is a Japanese domestic market chassis and was never sold new in the United States.
