Quick Removal Flanges 1-1/2in - 4pk.

The Quick Removal Flanges 1-1/2in - 4pk by Chassis Engineering are purpose-built disconnect points for high-performance automotive builds where modularity and serviceability matter. Whether you're fabricating a custom frame, building a tube chassis, or engineering a race car with detachable components, these four-bolt flanges provide a reliable, repeatable connection system that mechanics and fabricators trust. The 1-1/2-inch hole diameter accommodates standard fasteners while the compact 4-bolt pattern delivers strength without adding bulk to tight engine bay or frame configurations.

Each flange in this 4-pack features a 1/4-inch thick steel construction that resists flexing under load, critical when components experience vibration or thermal cycling. The natural steel finish provides a clean baseline for painting, powder coating, or protective treatment to match your build aesthetic. The 4-bolt configuration ensures even load distribution across the connection face, preventing stress concentration that can lead to premature fatigue or failure. All necessary hardware is included, eliminating the need to source fasteners separately and ensuring compatibility straight from the box.

Fabricators, engine builders, and chassis shops rely on these flanges for applications ranging from custom exhaust manifold adapters and turbo mounting solutions to frame junction plates and suspension component interfaces. The four-piece set accommodates multiple attachment points on a single project or supplies spares for ongoing shop use. Installation is straightforward—drill or match holes, bolt down with appropriate fasteners, and secure with lock washers to prevent loosening from vibration. These flanges work equally well in street performance builds, track cars, and off-road platforms where modular design simplifies maintenance and future modifications.
