Fit the GPM MAKS021 aluminium front knuckle arms to an ARRMA KRATON 4X4 4S BLX to increase front-end rigidity and achieve more predictable steering. Manufactured from 6061 T6 aluminium, the arms are designed for lasting resistance to impact and wear. Fitted POM collars control internal clearance so bearings sit firmly, cutting steering play. Three selectable mounting holes allow quick tie rod position changes to fine tune steering characteristics for different tyre choices.
