Chromoly Radius Weld Tabs

Chromoly Radius Weld Tabs for Race Car Tube Chassis

Pro-Werks Chromoly Radius Tabs combine the tube-conforming geometry of a radius tab with the superior strength of 4130N chromoly steel. Laser cut for dimensional precision, these tabs are engineered for builders who need a full-contact tube weld joint in a high-load or safety-critical application.

Why Chromoly Radius Tabs Over Mild Steel

When a high stength radius tab is needed at a suspension, steering, or structural attachment point, chromoly is the correct material choice. The curved base maximizes weld contact area on the tube, and the 4130 chromoly construction delivers the strength-to-weight ratio required for competitive racing applications. Choose chromoly radius tabs when:

  • Mounting rod end tabs directly to 4130 chromoly cage or chassis tubing
  • Building suspension pickup points where both geometry and strength are critical
  • The chassis is all-chromoly and material consistency is required at every weld joint
  • Weight savings matter — chromoly allows a thinner tab at equivalent strength to mild steel

Laser Cut Accuracy + Adjustable Radius

Laser cutting ensures consistent hole placement and edge quality across every tab. If the radius doesn’t match your tube diameter exactly, it can be quickly modified by grinding. Chromoly can be successfully welded to both mild steel and chromoly using the proper filler rod.
