Application: 1982-1992 GM F-Body: Camaro & Firebird with LSx Engine Swap


Spohn Performance's tubular k-member for the 1982-1992 F-Body Camaro and Firebird with LSx engine swap 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!

This tubular k-member is designed to be used with the stock style steering set-up, if you would like a tubular k-member set-up for Pinto manual rack and pinion steering click here.

Spohn's tubular k-member features boxed a-arm mounts for maximum rigidity and side load support. Our 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.

Our 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. 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 brake line mounts (there's no "zip tying" of the brake lines with our k-member) and optional front k-member brace mounts.

Build Specifications and Features:

  • 1.50" x .120" wall DOM tubing - one piece formed front hoop
  • 1.25" x .120" wall DOM tubing a-arm mount tubes 
  • CNC laser cut and formed 3/16" steel mounts and gussets
  • OEM style button head locating pins
  • 98-02 F-Body LS1 A/C compressor clears k-member with no modifications
  • Motor mounts are designed to clear all 98-02 F-Body LS1 A/C lines 
  • Welded in a special built rotary jig to insure an exact fit and precision welds entirely in the flat position 
  • Includes (6) new 12mm Grade 10.9 k-member mounting bolts and heavy flat washers 
  • Includes all four brake line mounts and new brake line mounting tab bolts and nuts
  • Durable and brilliant powder coated finish in your choice of the above colors  

Options - Select your options in the drop down boxes above:

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: This k-member is for those who are swapping in any LSx based engine (LS1, LS2, LS3, LS6, LS7, etc.), this version will also require our Part #971 LSx swap bolt on motor mount bushing adapter stands (
click here).

Front Brace Mounts: We provide the option of having front k-member brace mounts installed. All 1986-1992 cars were factory equipped with a triangular brace on each side of the front of the k-member to reinforce the front subframe at the steering box mount. These braces reduce flex and cracking of the front subframe and are a recommended addition for any street driven car. If you own a 1982-1985 car that was not factory equipped with the k-member braces, we also offer new triangular braces, make your choice. Note: K-member front braces will not clear the 98-02 F-Body LS1 A/C compressor or alternator. Only order the brace mounts/braces if you will be converting to the thirdgen style alternator set-up or using an aftermarket accessory set-up that mounts the alternator at a lower location.

4130N Upgrade: The ultimate in bullet-proof lightweight strength, 4130N chrome moly tubing construction! Same as above, but constructed from 1.50" x .083" and 1.25" x .095" 4130N chrome moly tubing.

Shipping Notice: Due to the variety of options we offer, k-members are built to order - Please allow 1-10 Business Days for shipment.
