Hellwig 78-87 GM G-Body 2dr (Excl. El Camino) Frame FX Kit

What you get with this Hellwig Frame FX kit are 14 pre-formed steel panels designed to reinforce the weak spots in your GM A/G Body's factory frame rails. This kit is a smart way to box your chassis, a process that significantly improves the vehicle's overall stiffness and handling characteristics without the guesswork of cutting and fitting raw steel yourself. It's a substantial upgrade for cars like the Chevrolet Monte Carlo, Buick Regal, or Oldsmobile Cutlass Supreme from 1978 through 1987.

Boxing the frame adds considerable strength, which translates directly into a more stable ride and better control, especially when you're pushing the car a bit. The panels are shaped to fit precisely into the factory frame, making installation more straightforward. Beyond just stiffening the chassis, this kit also adds an extra body mount point. This helps to better secure the floor pan to the chassis, contributing to overall stability. The design also incorporates a transmission crossmember mount that offers flexibility for different drivetrain setups, making it a well-rounded solution for performance-minded G-Body owners.

This is a serious upgrade for anyone looking to get the most out of their classic GM coupe. While it requires some mechanical aptitude and potentially welding to install properly, the result is a much more solid and responsive vehicle. If you're rebuilding the chassis or just want to improve the handling of your G-Body, this kit offers a comprehensive way to reinforce the frame.
