4130 Moly Chassis Tab - Flat - 3/8 Hole (4pk)

The 4130 Moly Chassis Tab - Flat - 3/8 Hole (4pk) by MEZIERE is a precision-engineered welding tab designed for custom chassis fabrication and frame modifications on performance vehicles. These tabs serve as critical attachment points when constructing or reinforcing chassis structures, engine mounts, or suspension components. Whether you're building a competition car, hot rod, or extensively modified street vehicle, having quality mounting tabs on hand ensures you can execute frame joints and structural reinforcements without compromise.

Manufactured from 4130 chromoly steel with molybdenum content, these tabs offer superior weldability and strength compared to mild steel alternatives. The 4130 composition provides excellent fatigue resistance—critical for high-vibration environments like engine bays and suspension attachment points. Each tab in this 4-pack features a flat profile with a 3/8-inch mounting hole, measuring 1.85 x 0.75 x 4.05 inches, allowing for versatile positioning and secure fastening. The chromoly material bonds cleanly under both MIG and TIG welding processes, reducing distortion and producing stronger, more reliable joints than standard steel tabs.

Fabricators, race car builders, and restoration specialists consistently choose MEZIERE tabs for chassis work where structural integrity is non-negotiable. The 4pk quantity makes this set ideal for multi-point attachment systems or keeping spares for future projects. Installation is straightforward—position the tab, drill or match the 3/8-inch hole to your frame, then secure via bolt or weld as your design requires. For any automotive enthusiast serious about custom fabrication, these chromoly tabs deliver the material quality and precision needed to build frames that last.
