Tein 90-93 Acura Integra Flex Z Coilovers

Tein Street Advance Z coilovers utilize the vehicle's original upper mounts. The design features a narrowed shell pipe top end, with oil and gas injected and sealed by crimping the metal, streamlining the production process and reducing cost. Ride height is adjustable by moving the lower spring seat. The twin-tube system offers longer stroke with smaller repulsive force compared to mono-tube systems, resulting in high ride comfort. A durable dust boot protects the piston rod from damage and keeps foreign material out of the shock absorber (some vehicles may use OE dust boots). Tein's unique ZT Coating surface treatment on the ride height adjustment thread provides abrasion resistance against gravel/debris and enhanced corrosion resistance. Tein claims zero stuck parts due to rust in 500,000 shock absorbers, ensuring rustproof performance even in harsh environments.
