SG / HMS Series
Tapered High-MisalignmentTapered sleeves that seat inside the ball bore, reducing the bolt diameter while extending the neck outward. Essential for off-road link travel.
Misalignment & Mounting Spacers for Rod Ends and Bearings
Rod End Spacers
Rod end spacers locate a rod end or spherical bearing in its mount and, in high-misalignment form, extend the angle the joint can travel before binding. SYZ supplies three families — high-misalignment spacers (SG stainless / HMS carbon steel), cone spacers (SCNS/CNS) and mounting spacers (SCW/CW) — in stainless and carbon steel, bore 1/4″–3/4″.

Mounting Hardware
What Are Rod End Spacers?
Rod end spacers sit between the rod end spherical ball bore and your mounting brackets.
They serve two primary functions: (1) locate and center the bearing inside a bracket to keep it running straight, and (2) in high-misalignment form, increase the tilt angle before the rod housing binds against the brackets. This is critical for active suspension travels.
Prevent Binding Failures: Under extreme articulation (droop or compression), standard mounting hardware can let the housing body bind against mounting brackets, bending the threaded shank or cracking the head. High-misalignment spacers resolve this by moving the pivot plane outward.
Product Selection
Choose Your Spacer Family
We manufacture three distinct designs in stainless steel (maximum corrosion resistance) and carbon steel.
SCNS / CNS Series
Cone LocatorsCone-shaped locating spacers engineered to center the rod end body inside brackets while retaining solid support faces.
SCW / CW Series
Straight SpacersStraight, uniform wall spacers used for general mounting setups, centering the rod end, or filling up gaps inside bracket brackets.
Sizing Guidelines & Stack Width
High-misalignment spacers are used in pairs (one on each side of the rod end ball). When sizing, verify that your bolt size matches the inner bore of the spacer, and that the combined stack width (spacer + rod end ball + spacer) matches your mounting bracket opening width exactly.
How High-Misalignment Spacers Work
Standard rod ends pivot until the housing contacts the mounting tabs. High-misalignment spacers (SG/HMS) solve this limits by inserting a tapered neck directly into the ball bore. This pushes the bolt contact face further outward, allowing the housing body to swing significantly further before binding.
For maximum articulation angles (e.g., severe off-road suspension setups), pair these spacers with a high-misalignment ball (HMBL) or step up to a specialized high-misalignment rod end series (HJMX).

Applications
Where Rod End Spacers Excel
Ensuring binding-free linkages across steering and suspension mounts.
Off-Road 4-Links
Required on crawlers and pre-runners to allow suspension trailing arms and panhard links to cycle through maximum travel arcs without binding.
Race Car Steering
Centers tie-rod assemblies inside mounting brackets. Eliminates steering bind under fast rack movements.
Industrial Machinery
Sets precise mounting gaps and preloads for actutator links inside brackets, ensuring clean, straight movement lines.
FAQ
Common Questions
What does a rod end spacer do?
It locates the rod end or bearing in its mount and sets preload; high-misalignment versions add angular clearance so the joint tilts further before binding.
What is a high-misalignment spacer?
A tapered spacer (SG stainless or HMS carbon steel) that lets a rod end articulate to a greater angle than standard mounting allows, common in off-road suspension.
Stainless or carbon steel rod end spacers?
Stainless (SG, SCNS, SCW) for corrosive, outdoor or marine use; carbon steel (HMS, CNS, CW) for general use at lower cost.
How do I size rod end spacers?
Match the bore to your mounting bolt, confirm the spacer stack fits your tab gap, and verify the resulting angle is within the rod end limit. Dimensions are on the spec pages.
Do spacers increase load capacity?
No. Spacers locate the bearing and set angle. Load capacity is determined by the rod end or bearing itself.
