Upgrade the front end of your Thunder Tiger K-ROCK MT4 with GPM front cupped seat ball collars. Crafted from POM Polyoxymethylene, these collars are built to reduce slop in the steering system and improve turn accuracy. Expect reduced friction and better dimensional stability so steering inputs feel cleaner and less prone to sudden kicks.
