Fanmao Adjustable Weld-On Shock Tabs for 3" Axle — 4-Pack, 1/2" Hole, 1/4" Thick

These weld-on shock tabs are made from low carbon steel with a plain finish and sized to fit 3" diameter axle tubing. Each tab features a 1/2" diameter bolt hole and 1/4" plate thickness, with hole centers spaced 1" apart to accommodate typical shock mounting hardware. Sold as a pack of four, the tabs arrive ready for welding (bolts not included), making them a practical choice for trailer, off-road, and custom axle projects where reliable shock attachment is required.

How do these tabs mount to a 3" axle and stay aligned?

These tabs are designed to be welded directly to 3" diameter axle tubing so the mounting face sits flush after tack-welding and full weld. The center-to-center hole spacing and flat backing give welders a predictable reference for alignment during installation.

• Fits 3" axle tubing diameter for direct weld-on installation
• Flat mating surface for consistent weld penetration
• 1" hole spacing keeps bolt alignment repeatable across mounts
• Pack of four lets you outfit both sides of an axle or keep spares

Will the 1/4" thickness and low carbon steel hold up under load?

The 1/4" plate thickness offers substantial shear and bearing area for common shock bolts while low carbon steel provides good weldability and toughness. For heavier vehicle or racing applications, users often reinforce welds or choose thicker tabs, but these tabs meet typical aftermarket and utility trailer demands.

• 1/4" thick plate for balanced strength and weldability
• Low carbon steel simplifies welding with common methods
• 1/2" bolt hole accommodates standard shock fasteners
• Plain finish allows post-weld painting or galvanizing for corrosion protection

What hardware and preparation do I need before welding these tabs?

Prepare the axle section by cleaning paint and rust to expose bare metal for a strong weld. Use a 1/2" bolt and matching nut or fine-thread fastener for the 1/2" hole; lock washers or threadlocker can help prevent loosening in vibration-prone applications.

• Clean welding area: remove paint, rust, and contaminants
• Recommended bolt: 1/2" diameter (bolt and nut not included)
• Welding: tack-weld then complete circumferential or fillet welds
• Protective finish: paint or galvanize after welding to prevent rust

How can I confirm these tabs fit my suspension layout?

Measure your axle outside diameter to confirm a 3" tube match and check the required shock eyelet spacing against the tab's 1" center spacing and 1/2" hole diameter. The relatively compact footprint of these tabs makes it easy to place them where needed for clearance and geometry considerations.

• Verify axle outer diameter is 3" before purchase
• Confirm shock eyelet diameter matches 1/2" hole size
• Plan tab placement to maintain shock angle and travel
• Use templates or mock-ups to test clearance before welding

Who is this for? These Fanmao weld-on shock tabs are ideal for DIY mechanics, trailer builders, and fabricators who need a reliable, weld-ready mounting solution for shocks on 3" axles. They suit light- to medium-duty utility trailers, custom off-road builds, and restoration projects where ease of welding, standard bolt compatibility, and a compact mounting footprint are priorities. If you need heavier-duty or pre-finished components, consider thicker tabs or coated alternatives.
