RPM A-arms for the 4×4 3S BLX versions of the Granite, Senton & Big Rock offer more adjustability, better durability, and lighter weight.

Adjustability: A second shock mount has been added to both front and rear A-arms to the outside of the stock shock mount, adding adjustability and improving trackability. RPM's 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 RPM's trademark blend of indestructible, engineering grade nylons. The shape of the A-arms has been redesigned while retaining stock suspension geometry to help improve survivability for those "oops" moments.

Lightweight: With RPM's stronger materials and improved designs, unnecessary weight has been cut out while still offering suspension components that are unparalleled in performance and durability.

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 Front A-arms replace ARRMA #AR330443.
