DESCRIPTION

ZETA Aluminum Free Piston – Replacement Kit for KYB AOS Twin Chamber Forks

Upgrade ride quality and durability with the ZETA Aluminum Free Piston, engineered as a direct replacement for KYB AOS Twin Chamber fork pistons. Designed to outlast the fragile OE plastic piston, this kit delivers consistent performance and improved fork feel.

Durable aluminum construction: Lightweight yet robust aluminum resists cracking and wear that commonly affects OEM plastic pistons.
Direct fit for KYB AOS: Precision-machined to match OEM dimensions for easy installation and reliable compatibility.
Two spring options:
- STD piston – preserves the original suspension character for stock-like response.
- Plush piston – provides a softer, smoother feel throughout the stroke for enhanced comfort and traction.
Improved consistency: Stable damping behavior across varying temperatures and conditions for better control.

Perfect for riders seeking a simple, effective upgrade to extend fork life and refine suspension behavior. Replace your OE piston with ZETA Aluminum for dependable performance ride after ride.
