Hellwig Frame FX Kit for ’68-’72 Chevelle

One of the most effective ways to improve the stiffness and handling of a Chevelle is to box the factory chassis. This process could take considerable time with measuring, cutting and fitting steel panels, however Hellwig Products is making the task easy and even more effective with their new custom fit Frame FX kit.

Most Chevelles have an open C-channel chassis that is
only 3” wide at the top and bottom. This design is
inherently weak in handling torsion and marginal in
bending. Hellwig’s Frame FX kit doubles the width of the tension side of the frame rail and closes the area for dramatic increases in torsional and bending stiffness.

The new Frame FX kit is made up 14 pre-cut 10-gauge steel panels that match the thickness of the factory frame and fit into the weak points of the factory chassis. Hellwig also engineered another panel that adds an extra mount to tie the floor to the chassis to add even more strength to the entire car. In addition, brackets are provided to mount the transmission crossmember with enough adjustment to accommodate nearly any drivetrain configuration.

The increased strength that the Frame FX kit provides results in handling and ride quality improvements while retaining the factory chassis and mounting points. If you’re adding a high powered drivetrain and bigger tires, the Frame FX Kit should be in your Chevelle’s future.
