RPM Rear A-Arms (ARRMA 3S BLX 4x4 Big Rock, Senton, Granite)

By:rpm rc products
Quantity: Only 1 left in stock.




RPM A-arms for the 4×4 3S BLX versions of the Granite, Senton & Big Rock are the answer to the questions you didn’t know you had. Are you looking for more adjustability? Check! How about better durability? Got that covered too. How about lightweight? Yup, no problem!


Adjustability: RPM has added a second shock mount to both RPM's front and rear A-arms to the outside of the stock shock mount, adding adjustability and improving trackability. RPM's 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 RPM's trademark blend of indestructible, engineering grade nylons, you can’t get much tougher! RPM has also redesigned the shape of the A-arms while retaining stock suspension geometry to help improve survivability for those “oops” moments.

Lightweight: With RPM's stronger materials and improved designs, RPM was able to cut out unnecessary weight while still offering suspension components that are unparalleled in performance and durability.
