Box-stock, the Blitz is quite a rugged truck but hard-core racers and bashers are managing to find its weaknesses. That's where RPM steps in. RPM A-arms and Bulkheads for the HPI Blitz, Firestorm RTR, E-Firestorm & E-Firestorm Flux are designed to eliminate those minor weaknesses in these otherwise strong competitors. Our goals were simple: Make them strong, make them slop-free and make them look great on the truck. Mission accomplished!
