RPM Front A-arms for the Typhon 4×4 3S BLX are everything you’re looking for in a set of replacement A-arms. Our versions are more adjustable, more durable and lighter than stock.

Adjustability: We’ve added a second shock mount to the outside of the original stock shock mount, adding adjustability and improving trackability. Our 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! We’ve also redesigned the shape of the A-arms while retaining stock suspension geometry to help improve survivability for those “oops” moments.

Lightweight: With our stronger materials and improved designs, we’re able to cut out unnecessary weight while still offering suspension components that are unparalleled in performance and durability. RPM Front A-arms are more than 5 grams lighter per A-arm than their stock counterparts!

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 Typhon 3s a-arms shown here while others use Granite 4×4 arms.
