RPM Rear A-arms for Arrma 3S 4x4 Electric Car/Truck

RPM A-arms for the 3S BLX versions of the Granite, Senton, and Big Rock, are the solution to your unasked questions. Looking for more adjustability? We've got you covered. Seeking better durability? We've got that covered too. How about a lighter weight option? No problem!

Adjustability is key, and we've added a second shock mount to both the front and rear A-arms, located on the outside of the stock shock mount. This provides additional adjustability and enhances trackability. The outer shock mount also lowers the ride height, increasing stability on all types of surfaces and allowing for faster corner speeds.

In terms of durability, our A-arms are molded from our trademark blend of indestructible, engineering-grade nylons. We have also redesigned the shape of the A-arms while maintaining the stock suspension geometry to improve survivability during those unexpected mishaps.

When it comes to weight, our materials and designs are stronger, allowing us to eliminate unnecessary weight while still offering suspension components that are unmatched in performance and durability.

TechNOTES: RPM A-arms are compatible with the following ARRMA vehicles; Big Rock 3S (#AR102711), Senton 3S (#AR102668, #AR102667, & #AR102678) & Granite 3S (#AR102665, #AR102666, & #AR102676). RPM Rear A-arms replace ARRMA #AR330516. Version CompatibilityNOTES: Big Rock owners should exercise caution and double-check the stock ARRMA part number of the A-arm being replaced. Some versions of the Big Rock use the Granite 3S A-arms featured here, while others use Typhon 3S A-arms.
