RPM 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 both our front and rear A-arms to the outside of the 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 Rear A-arms are more than 7 grams lighter per A-arm than their stock counterparts!
Tech Notes: RPM Rear A-arms replace ARRMA #AR330540.
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.
