Add serviceable articulation to a custom suspension link
RockJock RJ-301600-102 combines a forged threaded shank with cushioned, rebuildable internals for custom links that need controlled movement without a metal-on-metal joint. Its exact thread, mounting width, and bolt bore provide the dimensions needed to design compatible surrounding hardware.
Key Features
- Narrow-width 2-inch forged Johnny Joint configuration
- 34 degrees of manufacturer-specified articulation
- Serviceable one-piece urethane bushing internals
- 7/8-inch-14 right-hand threaded forged shank
- Externally greased through an installed 1/4-inch-28 zerk fitting
- Fully assembled and ready for dimension-matched installation
Fitment

FAQ
What is the RJ-301600-102?It is a narrow-width, forged 2-inch Johnny Joint rod end for dimension-based suspension and linkage fabrication.
Does this rod end have vehicle-specific fitment?No. It is a universal fabrication component that must be selected by thread, mounting width, bolt bore, articulation, loads, and clearance.
What thread does the shank use?The forged shank has 7/8-inch-14 right-hand threads, with 2.32 inches of threaded length.
What are the pivot-ball dimensions?The pivot ball measures 2 inches across its mounting width and has a 0.515-inch through-bore.
How much articulation does the joint provide?RockJock specifies 34 degrees of articulation for this narrow-width configuration.
What are the joint-body dimensions?The forged outer barrel is 2 inches in outside diameter and 1.20 inches wide.
How is the joint lubricated?An installed 1/4-inch-28 zerk fitting provides external greasing for the serviceable one-piece bushing internals.
Which grease and grease gun should be used?Use non-synthetic high-moly grease with a hand-pump grease gun; powered grease guns can over-pressurize and damage the joint.
Are a jam nut and weld-in bung included?No. The package contains one assembled forged Johnny Joint; the compatible jam nut, optional weld-in bung, mounting bolt, and grease are separate.
Installation Instructions
- Confirm that the engineered application requires the exact right-hand thread, 2-inch mounting width, 0.515-inch through-bore, and 24-degree articulation range.
- Verify the package label and manufacturer part number RJ-301600-102 before fabrication or installation begins.
- Have a qualified designer establish bracket spacing, link geometry, material grade, wall thickness, fastener specification, joint orientation, clearances, and expected loads.
- Thread the joint into a compatible 7/8-inch-14 right-hand link or bung with sufficient engagement, then fit the appropriate jam nut without forcing or cross-threading the shank.
- Align the pivot ball between dimension-matched brackets and install an application-rated fastener through the 0.515-inch bore.
- Set the link length and joint orientation, tighten the jam nut and mounting hardware to the engineered application specifications, and verify unrestricted movement through the full range.
- Check that hoses, wiring, chassis parts, tires, and other suspension components remain clear at full compression, droop, and steering travel where applicable.
- Lubricate only with non-synthetic high-moly grease and a hand-pump grease gun; stop before excess pressure can damage the joint.
- Reinspect thread engagement, fastener torque, clearance, and joint condition after the initial service interval and during routine maintenance.
