TL-ONE Thunder Lane Track Performance Single Adjustable Coilover for C5 & C6 Chevrolet Corvette

The TL-ONE coilover system for the Chevrolet Corvette C5 and C6 is designed for drivers who want real performance gains without compromise. Built around maximizing usable suspension travel and delivering predictable damping control, TL-ONE is ideal for high-performance street driving, track days, autocross, and Time Trial use.

Unlike generic off-the-shelf Corvette coilovers, TL-ONE is built to order and tuned specifically to your car. Spring rates, damper valving, shock length, and travel are selected based on how the car is actually used—resulting in better grip, improved compliance, and confidence at the limit.

Built to Order — Tuned to Your Corvette

Every TL-ONE kit is built from the ground up for your specific C5 or C6. Before production begins, we contact you directly to discuss your goals and vehicle configuration. Setup decisions are informed by:

• Tire type and size
• Total vehicle weight
• Desired ride height
• Sway bar configuration
• Corner weights (when available)
• Driving discipline (street, autocross, track days, Time Trials)

This approach allows us to preserve suspension travel—even at lowered ride heights—while delivering a damping profile that supports the chassis without unnecessary stiffness.

Damping Philosophy & Check Valve Design

TL-ONE uses a carefully tuned internal piston, shim stack, and check valve system to control how damping forces are distributed between compression and rebound. The check valve allows low-speed damping behavior to be tailored without compromising high-speed compliance, improving grip, stability, and ride quality over bumps, curbing, and surface irregularities.

This design is a key reason TL-ONE can deliver strong platform control without the harshness commonly associated with stiffer Corvette setups. Learn more about how the check valve works and why it matters.

1-Way Adjustable Damping

TL-ONE kits are offered with 20-click adjustable damping, configured as either:

• Rebound adjustment – controlling how the suspension returns after compression
• Symmetrical rebound/compression adjustment – depending on application and build goals

This adjustment range allows meaningful tuning changes for tire grip, balance, and surface conditions, without overcomplicating setup.

What’s Included

• 46mm monotube dampers
• Fixed-length shock bodies (no sleeves or excess dead space)
• 20-click adjustable damping
• CNC-machined top hats and mounts
• Pillowball / spherical bearing top hats
• Electroplated shock bodies and collars
• Helper springs
• Custom spring rates selected for your setup
• Shock body and spring length matched to desired ride height
• Application-specific valving with integrated check valve system

All TL-ONE kits are fully rebuildable, serviceable, and re-valvable, allowing the suspension to evolve as tires, alignment, or vehicle use change over time.

Upgradeable as Your Build Progresses

TL-ONE is designed as a foundation. As your Corvette build becomes more aggressive, the system can be upgraded to remote reservoir 3-way adjustable damping, adding independent low-speed and high-speed compression control for advanced tuning and thermal capacity.

Designed for Performance Driving

TL-ONE for Corvette C5 and C6 is ideal for drivers who prioritize grip, consistency, and usable travel over unnecessarily stiff setups. Whether the car is street-driven, track-focused, or used in competitive events, TL-ONE delivers clear feedback and predictable behavior lap after lap.
