J-Bar Body Aluminum 4in Body #3 15-1/2in Long

The J-Bar Body Aluminum 4in Body #3 15-1/2in Long from WEHRS MACHINE is a precision-engineered Panhard bar component designed for serious chassis tuning and suspension geometry control. Built for fabricators, racers, and suspension specialists who demand repeatability and accuracy, this aluminum body serves as the central mounting point in J-style Panhard bar assemblies. Whether you're dialing in a circle-track car, drag racer, or road-course platform, controlling lateral chassis movement with a properly tuned Panhard bar is non-negotiable for consistent handling and weight transfer management.

Manufactured from aluminum and finished in black anodize, the 4-inch body designation indicates the effective rod-end spacing, while the 15½-inch overall length provides the geometry needed for mid-width platforms common to circle-track and hot rod applications. The aluminum construction minimizes unsprung mass compared to steel alternatives, reducing rotational inertia and improving suspension responsiveness during direction changes. This design accepts standard rod ends (sold separately) at both ends, allowing custom length configurations and geometry tuning based on your specific frame width, desired anti-roll characteristics, and lateral stiffness requirements—critical variables in chassis setup that directly affect lateral weight transfer and tire loading during cornering.

This component is ideal for fabricators building custom suspension systems, race teams optimizing car balance, and restoration shops installing modern geometry control in vintage platforms. The universal J-style design works across multiple chassis types—from oval-track race cars and bracket racers to street rods and independent rear-suspension conversions—provided your frame geometry accommodates this bar length and mounting angle. Installation requires welding the body to a frame mounting point and installing appropriate rod ends for your application; detailed installation guidance and geometry specifications are essential before fabrication. Verify your specific rod-end thread size and overall bar length requirements before ordering, as final geometry setup is application-dependent.
