BMR TH400 Transmission Conversion Crossmember Red (TCC001R) - 1998-2002 F-Body LS1
Swapping a heavy-duty Turbo 400 automatic transmission into your LS1-powered Fourth Gen muscle car is a straightforward upgrade with a Transmission Conversion Crossmember from BMR Suspension. Factory stamped-steel crossmembers lack the durability required for modified high-horsepower builds and cannot accommodate high-performance racing transmission conversions without extensive, risky modifications. BMR’s high-strength tubular conversion crossmember replaces the weak stock component, providing a rock-solid structural foundation that sets the correct mounting height and drivetrain angle for your upgraded gearbox configuration.
Engineered to handle intense structural loads in high-performance street, heavy-duty drag racing, and demanding handling applications, this red powdercoated crossmember is manufactured right here in the U.S.A. It is crafted from premium 1.25-inch DOM steel tubing with laser-cut, CNC-formed 3/16-inch steel plate to offer uncompromised strength and stability. This heavy-duty design completely eliminates stock transmission crossmember deflection under extreme acceleration, keeping your drivetrain properly aligned for predictable, repeatable chassis reactions. It is a direct-fit upgrade that bolts straight into the factory frame mounting locations to completely eliminate custom fabrication guesswork. Installation takes approximately 1 to 2 hours.
NOTE: Unlike torque arm relocation styles, the BMR TCC001 crossmember is engineered strictly as a high-strength, direct structural transmission support mount for TH400 automatic gearboxes paired with LS1 engine combinations.
