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


I was wondering if these would fit on a 07 Accord. I know a lot of TL parts are interchangeable with the CM6 chassis and I was wondering if this was the case with these. Thanks!


This Tein TL kit is shared with a 7th generation Accord fairly, yes.

Q:What is the spring rate with the Flex Z set? I'm more into comfort now I've had stiff BC coilovers and K sports which I hated so I wanted to look at teins but was torn between street advance and flex Z set mainly because of included top hats also concerned about spring rate as well so which are better?

The spring rate on this kit should be 12 front and 6 rear. These are good "medium" rates. They will be compliant but sporting. The main plus with the Street Flex Z is the full-length adjustment which means that you can have more height options. If you are not looking to go more than about 2" down, the Street Advance is perfectly awesome! Although the springs are a bit softer with the SA/SAZ the ride will be more compliant. You aren't going to give up tons of performance either, so if you aren't tracking the car it should be a viable option. We're happy to give more direct consultation over the phone as well. 949-295-1668

Q:Do these come with top mounts as shown in the picture?

Yes, the Tein Street FLEX Z comes complete with upper mounts installed.

Q:Do these come with camber adjustments ?
A:No, your car will need adjustable control arms to adjust camber. We recommend kits from Skunk2, SPC, and Hardrace.

    I received my order which had to go through customs en route to Canada still arrived within a week! Great customer service and great coilovers. It's great that this kit comes complete no reusing of tophats which simplifies installation. Surprisingly supple ride and I have mine set pretty low. I didn't touch the spring preload and set the dampers according to their recommendation. I couldn't be happier highly recommend!

    Got these in and the wait was WELL worth it. Marcus helped pick out which ones would be best for what I was looking for. Got it shipped and it was fast! Installed them how they came from the factory(didn't mess with dampening or anything). Gave it a nice drop and rides SO great too. Can't wait to get the EDFC to try out the different dampening settings on this set up. If you're looking at getting the Street Basis or Advance Zs, get these instead. Quicker install time. Well worth it! Wanted this set up since I got into cars when I was 17. Glad I have it now.

    I've had a lot of cars and a lot of coilovers..bc, megan, vmaxx, etc but I have to say the hype about Teins is far best bang for your buck..everything about the flex is awesome..once dialed in the ride is amazing..firm but forgiving..and Marcus is straight forward, helpful and all around a great guy and awesome company.
