Transform your scooter's handling with the Forsa Performance Racing Shock Set. Engineered for high-performance GY6 150cc scooters, these 335mm (13.25") shocks feature a sophisticated nitrogen-charged internal dampening system. Unlike standard oil-only shocks that can foam and lose effectiveness under heat, the nitrogen charge ensures consistent, fade-free suspension performance — whether you're carving city corners or carrying a heavy load.
Key Features
- Nitrogen-Charged Dampening: Prevents hydraulic oil from aerating for a smooth, responsive ride over harsh road imperfections — no fade, no sponge.
- Step-Style Preload Adjustability: Threaded collar lets you fine-tune spring tension to match your riding weight and cargo load.
- Sport Aesthetic: Finished with a deep orange-red "Race Coil" for a high-performance custom look. Note: color appears more orange-red than true red.
- Taiwan Precision Manufacturing: Built by Forsa to exacting tolerances — superior seal life and durability vs. generic budget shocks.
