These GPM C-hubs are CNC machined aluminum components engineered to replace the stock plastic units on HPI Savage models including Savage X, XL and K4.6. The design focuses on improved dimensional accuracy and long term durability to deliver tighter steering geometry under load.
Produced with CNC machining to tight tolerances, the aluminium hubs reduce play in the steering assembly and offer a stiffer mounting point for knuckles and links. The result is improved steering feedback and consistent handling during aggressive driving or competition use.
