Product Description

The BMR KM013H tubular K-member replaces your heavy factory subframe with a lightweight, rigid alternative built from DOM steel. Designed for 1998-2002 F-Body Camaros and Firebirds, this turbo/LS1 version includes weld-in motor mount bosses for LS or turbo LS swaps and maintains compatibility with OE or aftermarket steering racks.

By removing stock cast-iron subframe stands and switching to integrated tubular design, it sheds approximately 42 lb when used with BMR A-arms while increasing chassis stiffness. Powder-coated in durable black hammertone, the KM013H is a bolt-in upgrade that improves performance, clearance, and sound foundation for performance builds.
