WOD Chromoly Four-Link Rod End Kit – 3/4"-16 Shank, 3/4" Bore
FL3434
The WOD Chromoly Four-Link Rod End Kit provides the joints, jam nuts, and stainless steel spacers needed to build one complete front or rear four-link suspension system. Designed around 3/4"-16 chromoly rod ends with 3/4" bores, this kit is a strong, serviceable option for trail rigs, rock crawlers, lightweight buggies, race vehicles, and custom chassis builds.
Each kit includes four left-hand-thread and four right-hand-thread rod ends, allowing suspension links to be adjusted without removing them from the vehicle. Matching jam nuts lock the final adjustment in place, while the included 3/4" stainless steel misalignment spacers provide proper mounting width and increased articulation at each suspension connection.
These are the same style of chromoly rod ends Wide Open Design trusts in real off-road suspension systems where strength, adjustability, and reliable joint movement matter.
Includes:
- (8) 3/4"-16 Chromoly Rod Ends with 3/4" Bore
- (4) Left-Hand-Thread Rod Ends
- (4) Right-Hand-Thread Rod Ends
- (8) Matching Jam Nuts
- (16) 3/4" Stainless Steel Misalignment Spacers
Note: This kit provides the rod ends and spacers required for eight suspension mounting points. Suspension links, threaded bungs, mounting tabs, bolts, and chassis brackets are sold separately.

Load ratings describe the stated radial static capacity of the rod end and do not represent the safe working load of the complete suspension system. Final capacity depends on link material, thread engagement, brackets, hardware, welding, suspension geometry, and vehicle use.
Fitment
Universal Fitment
Common Applications:
- Front four-link suspension systems
- Rear four-link suspension systems
- Trail rigs
- Rock crawlers
- Lightweight buggies
- Off-road race vehicles
- Custom tube chassis builds
- 7075 aluminum suspension links
- Heavy-wall steel suspension links
Fitment Notes:
- Designed for suspension links using 3/4"-16 threaded bungs or compatible threaded link material.
- Rod ends use a 3/4" bore and included spacers intended for 3/4" mounting bolts.
- Verify bracket width, spacer width, bolt diameter, and available articulation before installation.
- Use one left-hand and one right-hand rod end on opposite ends of each suspension link to allow adjustment without removing the link.
- Maintain sufficient thread engagement inside each link or threaded bung.
- Jam nuts must be tightened after final suspension alignment.
- Cycle the suspension through full compression, droop, and articulation to check for binding.
- Mounting tabs, bolts, threaded bungs, and suspension links are not included.
FAQ
What is included in a complete four-link rod end kit?
A complete four-link suspension uses four links with a joint at each end, requiring eight rod ends total. This kit includes eight rod ends, eight jam nuts, and sixteen spacers to service all eight mounting points on one front or rear four-link system.
Why use both left-hand and right-hand threads?
Installing a left-hand rod end at one end of a suspension link and a right-hand rod end at the other allows link length to be adjusted by rotating the link body. This makes it easier to set wheelbase, axle position, pinion angle, caster, and suspension alignment without removing the link.
When is a 3/4" rod end a good choice?
A 3/4" rod end is a strong option for lightweight to moderate-weight trail rigs, recreational crawlers, buggies, and custom suspension systems where reduced size and weight are beneficial. Heavier vehicles, larger tires, or severe competition use may require a 7/8" or 1-1/4" rod end system.
What do heim joint spacers do?
Heim joint spacers position the rod end correctly between the suspension tabs and provide additional clearance for articulation. The included stainless steel spacers are designed for a 3/4" mounting bolt and help reduce binding as the suspension cycles.
What is radial static load?
Radial static load is the amount of load applied perpendicular to the rod end bore that the joint is rated to withstand under a static test condition. It should not be treated as the safe working capacity of the complete suspension, especially under impact, fatigue, bending, or side-loading conditions.
How much thread engagement should a rod end have?
The rod end should maintain substantial thread engagement inside the suspension link or threaded bung at the final adjustment length. Avoid operating the joint near the end of its threads. Exact requirements depend on the joint, link material, and application.
Why are jam nuts important?
Jam nuts lock the rod end adjustment against the threaded bung or link. A loose jam nut allows movement in the threads, which can damage the shank, bung, or link and alter suspension alignment.
Can these rod ends be used with aluminum links?
Yes. This kit can be used with properly designed 7075 aluminum suspension links or heavy-wall steel links equipped with compatible 3/4"-16 threads or threaded bungs.
How do I prevent rod end binding?
Mock up the complete suspension and cycle it through full compression, droop, and side-to-side articulation. The joint must retain adequate angular movement at every position without contacting the mounting tabs or placing the shank in bending.
