TEIN has always aimed to stay at the forefront of offering high performance suspension with a strong emphasis on meeting our customers 1demand for affordability. Their latest products reflect their efforts in meeting those needs while maintaining their well-known manufacturing standards for quality. NEW for 2016 - Street Basis Z. The latest generation of TEINs existing Street Basis suspension kit incorporates many of the same technologies that have made them so popular by enthusiasts, but now made even more affordable by TEINs streamlined manufacturing processes and their new fully sealed damper structure. These new manufacturing processes drastically reduce starting prices for the new line for complete kits. 

Never before has TEIN been able to provide such high quality performance into an incredibly affordable package, until now. To date, this has been one of TEINs proudest achievements. Thread-type adjustable, Twin-Tube, Uses OE Mounts, Durable and Reliable, Non-EDFC Compatible. 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). Cold formed with SAE9254 steel (minimum tensile strength 200 kgf/mm2), TEINs springs are outstandingly sag-proof and boast extreme resiliency. Superior rust protection is ensured with a highly durable powder coating that does not peel or flake. TEINs high-quality springs can be used without worries, in any conditions.
