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 A-arms fit the ARRMA Typhon 4×4 3S BLX exclusively (#AR102696). RPM Rear A-arms replace ARRMA #AR330540.
