Description

The Summit Racing SUM-770322 transmission crossmember is engineered from durable steel with a black powdercoated finish for longevity and a clean aesthetic. Its patented double-hump design is a key feature, ensuring that ground clearance is not compromised by exhaust system routing, making it an ideal solution for those running dual exhaust systems. This crossmember is designed to fit a variety of popular GM transmissions, including the TH350, TH400, MUNCIE, POWERGLIDE, T-10, 200-4R, SUPER T-10, SAGINAW, and TH200. Fitment notes indicate that while this crossmember is generally compatible with GM A-Body vehicles from 1973-1977, specific considerations apply. For instance, some 1972 Monte Carlos with a narrower frame may accept this crossmember for TH350 or TH400 transmissions, but offset mounts will not fit. It has also been confirmed to fit a 1975 Cutlass with a TH350. Installation may require enlarging frame holes in some applications, as noted in user feedback for 1973-1974 442 models.
