Description

The Classic Performance Products (CPP) Transmission Crossmember, part number CP90171, is engineered for a direct fit on 1973-1987 Chevrolet and GMC C10, C20, and C30 trucks. Engine compatibility includes Small Block (SB), Big Block (BB), and LS engines. It also works with numerous automatic transmissions such as the 2004R, TH350, TH400, 4L60, 4L60E, 700R, and 4L80E. The design allows for straightforward, bolt-in installation onto the lower frame rail, matching up with all specified engine and transmission combinations. This crossmember is noted for its suitability for custom builds, restorations, or upgrades, and it can accommodate large diameter exhaust systems, making it ideal for lowered or 'slammed' trucks. It is manufactured to vehicle specifications for a precise fit.
