HPI Racing is proud to announce a new 17mm Hex Hub Conversion Set for the Savage. Bolting on this easy upgrade allows Savage truck owners to use 17mm hex hub wheels like our new Nubz wheels and tires. 17mm hex hubs decrease the stress on the wheels, helping to prevent stripped wheels when using high horsepower engines. Strong steel axles are used for durability, machined lightweight aluminum hubs and wheel nuts are used for quick acceleration and anodized purple for a custom look. One set comes complete with everything needed to upgrade a Savage truck, including four axles/nuts, a wrench, thread lock and grease.
