82-92 Fbody Spohn Performance Tubular K-Member – LSx Engine Swap w/Pinto Manual Rack Mounts


Model Number: 703-LSX-MRM
Spohn Performance

This tubular k-member comes equipped with Pinto manual rack mounts welded in place. It must be used with a Pinto manual rack as the rack mounts will interfere with stock style steering linkage. Front brace mounts are not an option on this k-member because they interfere with the steering shaft.

Spohn Performance’s tubular k-member for the 1982-1992 F-Body Camaro and Firebird sets a new, higher standard of performance and quality. When they designed this k-member, they 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. Their 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! This tubular k-member is designed to be used with Spohn’s Pinto manual rack kit.

Spohn’s tubular k-member features boxed a-arm mounts for maximum rigidity and side load support. Spohns k-members are gusseted in critical areas to ensure that a weld never breaks. They decrease overall weight, and provide much more room for large tube headers, turbo systems, etc.

Spohn’s k-member will accept stock a-arms, or for additional weight loss and performance enhancement we also offer tubular a-arms (click here). K-members are available set up for stock style coil springs or in a coil over version that eliminates the upper spring perch for additional weight savings. Their 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 brake line mounts (there’s no “zip tying” of the brake lines with this k-member).
