DSE Mini Tub Spring Kit - 3in Drop (041236DS) - 1970-1981 Pontiac Firebird
Give your second-generation Firebird a lower stance and the rear tire clearance needed for a serious street or Pro-Touring build with the Detroit Speed Mini Tub Spring Kit. Designed for 1970-1981 Pontiac Firebird applications, 041236DS combines 175 lbs/in leaf springs with the supporting suspension components needed for a Mini-Tub setup. The springs lower the Firebird 3 inches from factory ride height while delivering performance-oriented handling without sacrificing ride quality. When paired with available Detroit Speed Mini-Tubs, the system can accommodate rear tires up to 335mm wide.
Detroit Speed engineers these leaf springs with a tapered-leaf design and anti-friction pads between each leaf to help provide smooth suspension movement and a controlled ride. The package includes leaf springs, offset shackles, U-bolts, shocks, shock mounts, and mounting hardware, making it an ideal solution for Firebirds that already have Detroit Speed Mini-Tubs installed or builds where the Mini-Tubs will be purchased separately. A narrowed fuel tank is required for the Mini-Tub conversion.

Fitment Notes
A narrowed fuel tank is required with this Mini Tub Spring Kit. For 1970-1973 Camaro/Firebird applications, Detroit Speed lists 080181DS for applications requiring a Holley pump, 080113DS for carbureted engines, 080135DS Super Tank 1000, and 080172DS Super Tank LT1/4. For 1974-1975 Firebird applications, Detroit Speed lists 080182DS for applications requiring a Holley pump, 080115DS for carbureted engines, 080137DS Super Tank 1000, and 080173DS Super Tank LT1/4. Detroit Speed's current 041236DS product data does not identify the listed 1978-1981 narrowed tanks as Firebird applications, so fuel tank compatibility for 1976-1981 Firebirds should be verified before ordering.
