Version Compatibility Notes: Big Rock owners, please use caution and double check the stock ARRMA part number of the a-arm you are replacing. Some Big Rock versions use the Granite 4×4 a-arms shown here while others use Typhon 3S a-arms.
The RPM Arrma 4x4 Rear Or Front Suspension Arm Set is compatible with 4×4 3S BLX versions of the Granite, Senton & Big Rock. These optional arms offer increased adjustability, improved durability and reduced weight.
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.
