RockNut Kits
The RockNut Kits category features RockJock’s patented locking-nut solution designed to replace traditional jam nuts, delivering superior security, precision, and reliability in suspension and steering systems. Using a tapered, collet-style locking mechanism, RockNuts clamp joints with significantly greater force than standard nuts—making them ideal for high-stress off-road, rock-crawling, and heavy-duty 4×4 builds where vibration and articulation are constant.For detailed installation procedures and torque specifications, be sure to check our Instruction Manuals.
