WOD Chromoly Four-Link Rod End Kit – 7/8"-14 Shank, 3/4" Bore
FL7834
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 heavy-duty 7/8"-14 chromoly rod ends with 3/4" bores, this kit is built for heavier vehicles, higher horsepower, large tires, and aggressive off-road suspension applications.
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 secure the final adjustment, while the included 3/4" stainless steel misalignment spacers provide proper mounting width and smooth articulation.
These are the same style of chromoly rod ends Wide Open Design relies on for trail rigs, rock crawlers, buggies, race vehicles, and custom chassis builds where suspension strength and serviceability are critical.
Includes:
- (8) 7/8"-14 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 link 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
- Rock crawlers and rock bouncers
- Trail rigs
- Ultra4 and off-road race vehicles
- Custom tube chassis buggies
- Heavy-duty linked suspension builds
- 7075 aluminum suspension links
- Heavy-wall steel suspension links
Fitment Notes:
- Designed for suspension links using 7/8"-14 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 left-hand and right-hand threaded rod ends 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 joint 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 the 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.
Why choose a 7/8" shank rod end?
A 7/8" shank provides more material and greater radial static load capacity than a comparable 3/4" rod end. This makes it a strong middle-ground option for heavier vehicles and aggressive suspension systems without moving to the size and weight of a 1-1/4" joint.
What do heim joint spacers do?
Heim joint spacers position the rod end correctly between the suspension tabs and provide clearance for the joint to articulate. The included stainless steel spacers are designed for a 3/4" mounting bolt and help reduce binding throughout suspension travel.
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 running the shank near the end of the threads. Exact requirements depend on the joint, material, and application, so the link system should be designed by a qualified fabricator.
Why are jam nuts important?
Jam nuts lock the rod end adjustment against the threaded bung or link. A loose jam nut allows the joint to move 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 7/8"-14 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.
