HEAVY DUTY CONTROL ARM MOUNT PAIRDesigned to replace and upgrade the weak OE front lower control arm mounts. These heavy-duty weld-on brackets provide a secure mount when driving off road. Greater wall thickness combined with a welded reinforcement plate provide extra support to the axle. Vehicles without eccentric cam bolts, or without stock lower control arm bolts with the big washers will need to purchase a set of eccentric cam bolts to use these.
