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

Fanmao 4-pack adjustable weld-on shock tabs are steel mounting brackets designed to weld onto 3" axle tubing and provide a secure 1/2" bolt attachment point for suspension shocks or accessories.

These weld-on tabs offer a straightforward way to add or relocate shock mounting points on trailers, utility equipment, or custom axle builds. Machined from low-carbon steel with a plain finish and 1/4" thickness, each tab is sized for 3" outer-diameter axle tubing and includes a 1/2" bolt hole. Sold in a set of four, they streamline installation when modifying suspension layouts or repairing existing mounts.

How do these tabs fit a 3" axle and what are the mounting details?

The tabs are curved to match the circumference of 3" diameter axle tubing and have hole spacing and thickness chosen for common shock hardware. They weld directly to the axle and accept a 1/2" bolt through the mounting hole. The tabs’ center-to-center hole spacing and plate thickness support a stable connection for many aftermarket and replacement shock configurations.

• Designed for 3" outer-diameter axle tubing
• 1/2" diameter bolt hole to fit standard shock bolts
• Hole centers spaced 1" on center for predictable alignment
• 1/4" plate thickness for durable weld joints

What materials and finish should I expect, and how do they affect welding?

Each tab is stamped from low‑carbon steel and shipped with a plain (uncoated) surface. Low-carbon steel is familiar to most welders and brazers and generally accepts MIG, TIG, and stick welding without special pre-treatment. The plain finish means you can paint or coat the welded area after installation to protect against corrosion.

• Low-carbon steel for easy welding with common methods
• Plain finish allows for custom painting or undercoating post-weld
• Solid plate thickness yields reliable weld penetration without excessive heat distortion

Can these tabs be adjusted or aligned during installation?

While the tabs themselves are fixed plates, their curved profile and multiple holes allow installers to position and tack-weld, verify alignment, then finish-weld for a precise fit. Because each tab is sold in a pack of four, you can trial-fit and adjust placement on both axles before completing welds. They work well for both factory-style and custom suspension geometries when mounted carefully.

• Curved shape eases temporary tack welding and alignment
• Pack of four makes matching left/right placements simple
• Use tack welds to verify shock angles then complete full welds

What hardware is required and is any bolt included?

The tabs accept 1/2" diameter bolts, but the package does not include bolts, nuts, or washers. Choose grade and length appropriate for your shock eye or bracket and the specific loading conditions. Use locking hardware or thread-locking compounds to prevent loosening in high-vibration applications.

• Bolt size: 1/2" diameter (not included)
• Recommended: high-strength grade bolts for suspension use
• Include lock washers or nuts with locking features for safety

Who is this for: These adjustable weld-on shock tabs suit DIY mechanics, trailer fabricators, and vehicle modifiers who need a straightforward welded mounting solution for 3" axles. If you’re retrofitting shocks, repairing damaged mounts, or building a custom axle setup and you have basic welding skills, this 4-pack gives repeatable mounting points that can be aligned and finished to match your suspension requirements.
