About this part

The RPM Arrma 4x4 Front Suspension Arm Set offers increased adjustability and improved durability in a lightweight package. 

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. This 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, 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 are able to cut out unnecessary weight while still offering suspension components that are unparalleled in performance and durability.

Features:

  • Fits 3s BLX 4×4 versions of the Big Rock, Granite & Senton
  • Exclusive 2nd shock mount hole for added adjustability
  • Replaces stock AR330443

NOTE: 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.

Rpm durability. The stock ones are good Quality but wanted to add durability by using rpm aftermarket spares. Installed the shocks un the normal position.
