The Tein Flex Z is a product line that is evolved from the STREET FLEX SF damper kit system. Historically, FLEX kits from Tein are sets which are readily adapted to many uses, from street to track driving. For the STREET FLEX SF variant, Tein softed the damping levels and extended stroke range to make the damper kits more tractable for daily use. For many years, Tein product carried the banner of performance value by making damper tubes that could be torn down, overhauled, and re-valved.

As the market evolves with emerging entrants and an increasing need for value, Tein re-designed their popular STREET FLEX SF line and renamed it the FLEX Z. The "Z-line" moniker has been added to the Street Advance Z and Street Basis Z, and represents a damper tube with similar internal construction as the outgoing overhaul-available "non-Z" product, but a new outer tube which is sealed. Rather than rebuilding worn dampers, users now will simply purchase replacements.

Newer manufacturing techniques, as well as revised springs that do not need spring seat adapters, allow the new Z-line to come in at a lower MSRP. Tein has literally reset the typical value proposition for assembled full-length damper kit with the FLEX Z. Many users are surprised at the pricing that Flex Z dampers can be had at assuming they are a compromise in quality, or that they are now made in China rather than in Japan. Neither is correct as these parts are still made from scratch in-house by Tein Japan with much of the same internal components that have made Tein products reliable and refined solutions for street-sport applications.

Tein Flex Z offers many features highly valued by users including:

  • Twin-Tube System for Comfortable Ride on Streets
  • Full-Length System for Ride Height Adjustment w/ Minimal Change in Ride
  • Damping Force Adjustable to Change Ride to Desired Settings
  • Compatible with EDFC Series to enable In-Car Damping Force Adjustment
  • Upper Mounts Included for Easy Installation
  • Highly Durable & Reliable
  • Thoroughgoing Rust-Proofing
  • Smooth Ride Height Adjustment & One-of-A-Kind Adjusting Wrench
  • No-Sag Springs
  • High-Spec Damper Oil

Customer Questions

Q:Does the street advance Flex Z coilovers come with the top mounts ready to swap in as pictured? I'm asking because I know TEINS usually don't come with the Top hats

The picture provided is the ACTUAL kit you will receive for your 9th gen Accord. Yes, the FLEX Z comes with upper mounts installed already. Many Tein systems come with upper mounts. But the Street Advance/Street Basis kits you are used to seeing do not. The FLEX Z is a newer line for the 9th generation Accord and they do come with upper mounts and are camber-adjustable in the front.

Q:What are the potential ride height adjustments, and what is the minimum recommended drop with these? I'm looking for a better-handling suspension for my 2016 Accord V6 Coupe with minimal ride height decrease.

The FLEX Z is an awesome kit for overall street performance, and a lot of height range adjustment. However for more moderate lowering along with a comfortable street ride, we might also recommend the Tein SAZ damper kit.

Q:As far as the ride height and comfort, how is this compared to the saz?

The Flex Z is in general valved with the same goal as the SAZ, with great general street comfort and upgraded performance over stock. The FLEX Z will offer more in the way of street performance though, and more lowering.

Q:How low can these go compared to the street advance z? Im debating between these or the flex z? my decision was more toward the street advance z since it uses factory top hats so that would reduce any risk of noise later on.

The FLEX Z is usually able to lower around 3" at maximum. The Tein upper mounts are not usually prone to noise but we agree that the factory upper mounts have a better NVH profile for everyday use. The SAZ will lower around 2.25" at the maximum, able to eliminate wheel gap.

Q:What is EDFC? Does it come with this system or is it an additional accessory? I have a 2013 Accord Coupe. I'm interested in upgrading to significantly improve handling and overall driving performance/enjoyment. The stock suspension is way too soft and has a TON of body roll.

The EDFC is a "remote controller" for adjustsable Tein suspensions like the Street Advance and Flex models. Learn all about the optional (not included) EDFC here: Tein's EDFC: What Is It, Why Get It, & How To Order

Q:Will a suspension upgrade (e.g. a coilover system like Tein Flex/ Tein Street advance) provide a stiffer feel in the steering wheel?

Not usually, no.
