The GPM aluminium rear knuckle arm set is made for the ARRMA KRATON 6S BLX Monster Truck to deliver improved durability and steadier rear tracking. The parts are engineered to support the universal joint and bearing for consistent performance in demanding conditions.
Produced from high grade aluminium with POM plastic components, these knuckle arms reduce play between the bearings and steering cup to achieve a snug, accurate fit. That construction increases rigidity and helps avoid distortion or disassembly during intensive running.
Each arm includes four distinct mounting holes on the upper section, allowing you to vary the tierod angle to match driving preference or surface type, giving better control over rear steering response.
