The GPM aluminium rear knuckle arm set is engineered for the ARRMA KRATON 6S BLX Monster Truck to deliver improved structural integrity and reliable bearing alignment. These components stabilise the universal joint and bearing under load to maintain predictable rear drive behaviour.
Constructed from aluminium paired with POM plastic parts, the knuckle arms are designed to minimise bearing-to-steering cup clearance for a precise fit. The material pairing increases torsional rigidity and reduces the risk of deformation or unexpected loosening during heavy use.
Four upper mounting holes provide selectable tierod angles so you can tune rear steering geometry for specific terrain or driving style, enabling more precise handling adjustments.
