Coming from Pro-Line and made for the Traxxas X-Maxx are the new Pro-Arms upper and lower arm kit as well as the Pro-Hubs rear uprights. Starting with the arm kit, the US-made kit includes cutting edge race-style black arms with smooth bottoms that are capped off with stone gray stiffening plates resulting in extremely durable and rigid arms. The arm plates are held on by multiple flat head screws and the stone gray colour is the exact same as Pro-Line’s Impulse Pro-Loc wheel rings so they can be dyed or painted to match the truck’s style. The Pro-Arms are direct replacements for the stock X-MAXX arms and are designed from the ground up to be nearly indestructible. Each arm kit includes a set of two upper and lower arms along with the stone gray plates and hardware. The Pro-Arms are cored out from the top to save weight and the arm plates keep dirt, mud and debris out of the arms.
As for the Pro-Hubs, the US-made rear uprights have been designed to be extra beefy and include high quality oversized inner 20x32x7mm ball bearings that can handle more load than the small stock bearings. The outer bearings must be re-used from the stock truck. The hubs are moulded from highly durable black nylon material and stiffness is maintained through deep ribs that are moulded into both the left and the right hubs. The Pro-Hubs are direct replacements for the stock X-Maxx rear hub carriers and pair perfectly with Pro-Line’s Pro-Arms wishbone set.
