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 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 Rear A-arms replace ARRMA #AR330516.
