DSE Mini-Tub Kit - 3in Drop (041227DS) - 1970-1981 Pontiac Firebird
Give your second-generation Firebird the room it needs for a wider rear wheel and tire package with the Detroit Speed Mini-Tub Kit. Designed specifically for the 1970-1981 Pontiac Firebird, this complete rear Mini-Tub package combines 2.5-inch-wide Mini-Tubs with 3-inch-drop leaf springs and the supporting suspension and mounting components needed for the conversion. The result is additional rear tire clearance, a lower stance, and a clean installation engineered to retain a factory-style appearance.
Detroit Speed engineers the Mini-Tubs for a precise fit and stamps them from durable 18-gauge steel in the USA. The included 175 lbs/in leaf springs provide the specified 3-inch drop, while offset shackles, Mini-Tub shocks, shock mounts, U-bolts, and related mounting hardware bring the major pieces of the conversion together in one matched package. For builders who want serious rear tire room without piecing together a Mini-Tub system component by component, 041227DS provides a purpose-built solution for the second-generation Firebird.
