Description
RPM Rear A-Arms For Arrma Typhon 3S / Big Rock V3, part number RPM80842, are replacement suspension arms designed around the stock suspension geometry. The listing identifies these arms for ARRMA Typhon 3S and Big Rock V3 models, while the manufacturer notes that Big Rock versions should be checked carefully before fitting because some use Granite 4x4 arms instead.
Design and Adjustment
These A-arms add a second shock mounting position outside the original stock mount. This provides an additional setup option and allows the ride height to be lowered, which the manufacturer states can improve stability across different surfaces and support faster cornering. The arm shape has also been redesigned while retaining the stock suspension geometry.
RPM moulds the arms from its engineering-grade nylon blend. The design removes unnecessary material while retaining the revised arm structure, making each arm more than 5 grams lighter than its stock counterpart. This combination of revised geometry, added shock adjustment and reduced weight provides a direct suspension component replacement for suitable applications.
Suggested Compatibility
Suggested compatibility includes the ARRMA Typhon 4x4 3S BLX and selected Big Rock V3 versions. The manufacturer lists these arms as replacing ARRMA part number AR330543, but Big Rock owners should compare the part number on the original arm before fitting. Different Big Rock versions may use Granite 4x4 suspension arms rather than the Typhon 3S type.

Specifications
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!
Tech Notes:
RPM Front A-arms replace ARRMA #AR330543.
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.
