RPM A-arms for the 4×4 3S BLX versions of the Granite, Senton & Big Rock are the answer to the questions you didn’t know you had. Are you looking for more adjustability? Check! How about better durability? Got that covered too. How about lightweight? Yup, no problem!
Adjustability: RPM added a second shock mount to both the front and rear A-arms to the outside of the stock shock mount, adding adjustability and improving trackability. RPM outer shock mount lowers the ride height, increasing stability on all surface types. A lower ride height also means faster corner speeds.
Durability: Molded from our trademark blend of indestructible, engineering grade nylons, you can’t get much tougher! RPM also redesigned the shape of the A-arms while retaining stock suspension geometry to help improve survivability for those “oops” moments.
Lightweight: With RPM's stronger materials and improved designs, they were able to cut out unnecessary weight while still offering suspension components that are unparalleled in performance and durability.
Tech Notes: RPM A-arms fit the following ARRMA vehicles; Big Rock 4×4 (#AR102711), Senton 4×4 (#AR102668, #AR102667 & #AR102678) & Granite 4×4 (#AR102665, #AR102666 & #AR102676). RPM Rear A-arms replace ARRMA #AR330516.
