Rear A-arms for the HPI Blitz, Firestorm 10T & E-Firestorm
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 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!
Strength is always a number one priority when we design aftermarket
parts for any vehicle. By increasing the thickness of the material
around both the inner and outer hinge pins, splitting A-arms at the
hinge pins will be a thing of the past. We also focused on the hinge pin
retaining system used on the stock A-arms. Using a small screw hole so
close to the hinge pin like the stock arms do weakens the A-arms at that
point. We moved the hinge pin retaining screws in-line with the hinge
pins, significantly strengthening our A-arms in the process.
Our next objective – eliminate the slop – was a simple matter of
using closely controlled materials processing and tight mold tolerances
to allow a free moving suspension system without unnecessary free play.
We tightened the sizes around the hinge pins and eliminated fore and aft
movement at the inner and outer hinge pins. The end result is a
suspension system that will hold camber and toe settings nearly perfect,
even under the toughest of conditions.
Our final objective – to create a great looking set of suspension
arms – came from our standard practice of beveling the leading and
trailing edges of the A-arms. The 30-degree angles create a slim
profile, which not only looks great but also cuts through the dirt and
air to help reduce overall drag. Form and function, all rolled into one!
