RPM A-arms for the 4x4 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 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 a trademark blend of indestructible, engineering grade nylons, you can't get much tougher! They've also redesigned the shape of the A-arms while retaining stock suspension geometry to help improve survivability for those "oops" moments
Lightweight: With stronger materials and improved designs, there is less unnecessary weight while still offering suspension components that are unparalleled in performance and durability
