DSE Mini-Tubs (040402DS) - 1968-1974 Chevrolet Nova / Oldsmobile Omega / Pontiac Ventura
Make room for serious rear tire under your classic GM X-Body with Detroit Speed Mini-Tubs. Designed for 1968-1974 Chevrolet Nova, Oldsmobile Omega, Pontiac Ventura, and related applications, part number 040402DS replaces the factory inner wheel housings with wider stamped-steel tubs that provide the additional clearance needed for performance-oriented wheel and tire combinations. At 2-3/4 inches wider than stock, these Mini-Tubs can accommodate tires up to 315mm wide while retaining a clean, factory-style appearance.
Detroit Speed stamps these Mini-Tubs from 18-gauge steel and engineers them for a precise vehicle-specific fit. Unlike a completely custom wheel tub conversion that requires fabricating the basic tub structure from scratch, the Detroit Speed system provides purpose-built inner wheel housings along with closeout and flange templates to help streamline installation. A narrowed fuel tank is required and available separately. The Mini-Tubs are manufactured in the USA and sold as a pair for a complete left- and right-side conversion.
