S197 Panhard Bar, Brace & Axle-Centering Parts

OEM service listing verified as 5R3Z-4264-AA for 2005-2014 Mustang stock track/panhard bar. 4R3Z-4264-AA appears as an older/alternate catalog listing and needs final counter cleanup before printing a clean OEM chain. Ford Performance M-4264-A is an upgrade part, not the stock replacement chain.

Gate 1 verified for 2005-2014 S197 solid-axle Mustang panhard/track bar. Trap: lowered cars need adjustable length to recenter the axle; stock bar is non-adjustable. A panhard bar controls side-to-side axle location; a Watts link is a different upgrade page, not the same part.

Checked paths: genuine Ford 5R3Z-4264-AA fixed-length replacement; Ford Performance M-4264-A adjustable bar. The stock bar restores factory lateral location; lowered cars generally need an adjustable bar to recenter the axle. A Watts link is a different system and is excluded.

Fixed OEM-style and adjustable bars solve different needs. Lowering can shift the axle laterally, which is why an adjustable bar is useful. Tighten suspension bushings at the specified ride-height condition and align/recenter carefully. A Watts link is outside this page.
