The ride height can be adjusted by moving the lower spring seat up or down. The characteristics of this system are its simple structure and ease of use. Compared to the regular mono-tube system, twin-tube attains longer stroke with a smaller repulsive force, resulting in high ride comfort. Thanks to its smooth compression and high durability, the dust boot guards the piston rod from damage, and keeps foreign material out of the shock absorber. (Some vehicles use their OE dust boots). Tein's unique ZT Coating surface treatment on the ride height adjustment thread is abrasion resistant against gravel/debris, and further enhances its corrosion resistance. With zero claims for stuck parts due to rust in 500,000 shock absorbers, TEIN shock absorbers are amazingly rustproof.
STREET ADVANCE Z and STREET BASIS Z use the vehicle's original upper mounts (not included in our product kit)
