TL-ONE is Thunder Lane US’s single-adjustable coilover platform built for drivers who want real track-capable damping without unnecessary complexity. Whether you’re chasing lap times in Time Attack, Autocross, HPDE, or building a weekend canyon car that still needs to behave on imperfect pavement, TL-ONE delivers the balance that matters: control, compliance, and consistency.

Every TL-ONE set is hand-assembled to order in Poland and valved around your vehicle and goals. That means the suspension isn’t “one-size-fits-all” — it’s configured to match the way you drive, the grip you run, and the response you want from the chassis.

Rebound-Adjustable Damping, With True Separation

TL-ONE uses a rebound adjuster designed for meaningful changes you can feel on track—adding support and control when you need sharper response, or backing it off for increased compliance on rougher surfaces. Unlike designs where a single adjuster can unintentionally influence both directions, TL-ONE’s internal check valves help prevent compression “crosstalk”, keeping rebound tuning focused and predictable. Learn what the check valve does and why it matters .

High-End Hardware & Monotube Performance

  • 46mm monotube dampers for consistent performance and heat management
  • Advanced piston technology for stable damping across a wide operating range
  • Check valve architecture to support chassis control while maintaining bump compliance
  • Electroplated damper bodies for durability and long-term corrosion resistance
  • Spherical bearing top hats for precise steering feel and repeatable alignment under load
  • Camber plates included where the application supports them

Built for Motorsports — Validated by Results

Thunder Lane dampers have a track record on competitive cars across Time Attack, Hill Climb, and circuit racing. TL-ONE brings that same engineering approach to a streamlined, single-adjustable package — ideal for drivers who want a serious suspension foundation with straightforward tuning.

Dyno-Tested, With Graphs Included

Every TL-ONE order includes dyno graphs (CVP and PVP) so you can verify damping behavior and document your setup. It’s the kind of transparency and quality control that matters when you’re tuning a car for real performance. How to Read Shock Dyno Sheets (and what they tell you about real world grip)
