Description
A mass damper that pivots on a ball-link joint rather than a rigid mount, intended for courses with heavy elevation changes where a swinging weight helps settle the chassis on landing. The 6x6x32mm mass unit weighs 8.3g and mounts low on the chassis for a lower center of gravity. This Japan Cup 2025 edition uses a mint-green carbon plate printed with commemorative logos and graphics, plus a glass-fiber-reinforced resin adjuster in red that resists popping loose on hard landings. It bolts straight onto MA or AR chassis without modification.
- Contents: one 6x6x32mm mass damper (8.3g), adjuster, carbon plate, pivot ball, and mounting hardware
- Direct fit: MA, AR chassis
- Also fits (via GP.430): MS, FM-A, VS, VZ, Super II/X/XX/TZ-X chassis — some bodies require trimming
