Jam Nuts
The Jam Nuts category contains locking nuts designed for adjustable rod ends, control arm ends, and other threaded components in performance suspension systems. Available in a wide range of thread sizes and right- or left-hand configurations, these jam nuts are essential for locking suspension geometry and preventing loosening under vibration, articulation, and heavy loads. To ensure you are following the correct torque specifications and assembly procedures, please consult our Instruction Manuals.
Features
- Threaded jam nuts ranging from smaller sizes (e.g. ¾-16) to larger sizes (e.g. 1¼-12 or 1-14), matched to common rod-end and suspension-joint threads.
- Right-hand (RH) and left-hand (LH) thread options to suit different joint orientations and adjustable suspension designs.
- High-strength steel construction with corrosion-resistant zinc plating, built to handle vibration, load, and harsh off-road environments.
Why Jam Nuts Matter
- Locking suspension adjustments
Jam nuts secure adjustable links, rod ends, and control arms once proper length and alignment are set, preventing movement or backing out during use.
- Resistance to vibration and load
In lifted or off-road vehicles where components see constant motion and stress, jam nuts act as a simple but effective locking solution.
- Compatibility with adjustable joints
Designed to work with threaded rod ends and heim joints, jam nuts allow easy tuning, re-adjustment, and service without specialized hardware.
Typical Use Cases
- Securing adjustable control arm or steering component rod ends after alignment or geometry tuning.
- Locking rod ends or heim joints in place to prevent loosening from off-road vibration and articulation.
- Use with adjustable link rods where threaded components must remain fixed.
- Custom suspension fabrication, repairs, or upgrades that require adjustable yet secure joint connections.You can find our full range of jam nuts and authorized installation services through our Dealer Locator.
