82-92 Fbody Spohn Performance Tubular K-Member – SBC / BBC / LT1 / 3.8L V-6 with Pinto Manual Rack Mounts


Model Number: 703-MRM
Spohn Performance

Tech Notes: 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 sets a new, higher standard of performance and quality. When they designed the 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 the drag race customers, but it also provides the strength, rigidity, and durability for the road race, autox, and daily driver customers as well….. all in one package! This tubular k-member is designed to be used with the Pinto manual rack kit.

Spohn’s tubular k-member features boxed a-arm mounts for maximum rigidity and side load support. These 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 they also offer tubular a-arms. These 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. The 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 these k-members).

Spring Type: K-members are available set up for a stock style coil spring, or in a coil-over version that eliminates the upper spring perch.

Motor Mount Pads: K-members are available with no motor mount pads for those who will be using a motor plate, or with mounting pads that will accept standard small block, big block, LT1 or 3.8L V-6 motor mounts. Note: If you will be using any block mounted motor mounts then you must get the motor mount pads installed on the k-member. The motor mount pads are what the block mounted motor mounts bolt fast to on the k-member.
