GM's 2nd gen F-bodies suffer from torsional twist due to their half frame design and from engine torque as well as from suspension loads.

PTFB's G-braces triangulate the frame to the rest of the chassis, these easy to bolt in braces have proven indispensable in any performance application.
The enspiration for these braces come from a renoun GM engineer, PTFB modernised and improved upon the design to fit 70-81 F-bodies.

  • Fit with stock A/C (on some early cars may need a valve relocated)
  • ​​​​​​​Fit Pontiac engines with tall valve covers.
  • Fit Small block Chevy.
  • Fit most LS applications depending on coil pack location and covers.
  • Will NOT fit BBC.

NOTE: solid body bushings are required.
