1998-2002 LS1 F-Body Tubular K-Members

BMR Tubular K-members are designed to provide a lightweight alternative to the factory K-member as well as provide additional clearance for aftermarket headers and turbo systems. Our unique design on our V8 models feature integrated frame stands that replace the factory cast iron frame stands. This additional weight reduction allows us to use larger diameter tubing and thicker mounting plates for additional strength over the competition. This means that you can use the K-member for street use, road race, autocross, or drag strip use. BMR K-members are built exclusively using larger diameter 1-5/8" x .120" and 1-1/4" x .095" tubing yet still remain up to 7.5 lbs. lighter than the competitions due to our integrated mount design. Using our tubular K-member and upper/lower a-arm set, expect a minimum weight reduction of 42 lbs. Combine this with a coil-over style spring/shock combo and a lightweight front brake setup and lose over 100 lbs. off the front end! Available in Black Hammertone or red powdercoat.

BMR also answers your requests with specialized versions of our K-members. We make K-members for manual rack conversions, high clearance variations for turbo downpipes, conversion K-members for traditional small and big block motor transplants, etc.

Extra Features

• Larger diameter tubing than most competitors to increase durability. Equally at home on the street, road course or drag strip
• Lighter than other competitors K-members due to integrated motor mount design
• Additional 1/4" of A-arm adjustability provides up to 4 degrees of additional camber adjustment
• Works with stock A-arms or any aftermarket A-arms

Looking to lighten up the front end of your late model Camaro or Firebird? Performance Automotive's Tubular K-Member can drop up to 60 lbs off the nose of your car! K-Members utilize factory hardware and are designed for a precise "OEM style" fit. All of PA Racing's parts are 100% made in the USA, using only the highest quality materials and accurate jigs. Choose from red or black powdercoated finish. PA K-Members can be used with either stock or aftermarket A-arms. See our suspension section for a complete listing of upper & lower A-arms (control arms.)

Spohn Performance's tubular k-member sets a new, higher standard of performance and quality. When we designed our k-member, we had several goals in mind. One was to provide the performance capabilities needed for the toughest race tracks, another was to provide the strength and durability required for the demands of a daily driven vehicle. Our k-member provides substantial weight savings and frees up a lot of room in the engine bay for our drag race customers, but it also provides the strength, rigidity, and durability for our road race, autox, and daily driver customers as well..... all in one package! Spohn's tubular k-member features gusseted a-arm mounts for maximum rigidity and side load support. Our k-members are gusseted in critical areas (over 20 locations!) to ensure that a weld never breaks. They decrease overall weight, and provide much more room for large tube headers, turbo systems, etc.

Our k-member will accept stock a-arms, or for additional weight loss and performance enhancement tubular a-arms can be added. Our jig was built around the factory k-member providing for an exact fit and factory exact dimensions. Every detail of the factory k-member was incorporated, including all five brake line mounts. There's no "zip tying" of the brake lines with our k-member.
