Mini-Tub Leaf Spring Suspension System


Technical Data Sheet
Installation Guide


The mini-tub leaf-spring suspension from Total Control Products allows substantially greater clearance for extremely large tire and wheel combinations. Relocated shocks and springs combined with the additional mini-tub clearance allow 2-3/4” more tire clearance on each side of the vehicle. Systems include all mounts, offset frame rail inserts, leaf springs, spring plates and shock absorbers. A panhard bar version of the suspension is also offered for sharper and more predictable handling. Optional components include a narrow-width, adjustable-rate anti-roll bar and fabricated Ford 9” housing (FAB9™). Currently available for all styles of 1964-70 Mustangs.

NOTE: '65-66 GT rear valance is not compatible with suspension.

Offset Frame Rails and Mini-Tub Option

Some vehicles may already have mini-tubs installed. For this reason we offer our mini-tub set and offset frame rails as options for the g-Link Suspension. Our fully-boxed rails provide 2-3/4" additional clearance and a significant increase in strength over modified factory rail channels.
