NCY Adjustable Shock; Genuine, 139QMB, GY6

NCY Nitrogen gas charged and multi-adjustable rear shock for Genuine Buddy 50-170cc scooters and most 139QMB 50cc and 125/150 GY6 models.  This performance shock will allow you to adjust ride height and compression/rebound dampening with a 25-point adjuster.  

Features:

1. Billet Machined Aluminum Performance Shock with Black Anodized finish
2. Adjustable Spring Pre-load Preload is used to compress or decompress the shock spring to the desired range of operation within the suspension's travel.  More preload will raise the bike upwards, keeping you near the top range of suspension travel. Less preload will lower the bike closer to the bottom range of suspension travel.
3. 25-point Shock Dampening Adjuster Turning the adjustment knob clockwise makes the shock dampening stiffer while turning it counterclockwise makes shock dampening more compliant.
4. Nitrogen gas charged - Nitrogen gas charge in the shock body resists heat build-up and prevents expansion, unlike oxygen resulting in more consistent shock performance under high demand.
