Level 1 Chassis Stiffening Pack 70-74 Plymouth Cuda E Body

This Level 1 chassis stiffening pack fits 70-74 Plymouth Barracuda and Cuda E-bodies. Your Mopar has no full-length frame. Instead, the front frame rails and the rear rails stop short, so the floor pan has to carry the load between them. As a result, the body twists under hard launches and cornering. Frame connectors bridge that gap, while torque boxes reinforce the points where the suspension feeds force into the unibody. In fact, the factory added torque boxes to some of its highest-performance cars for exactly this reason.

What’s in this Level 1 chassis stiffening pack for the 70-74 Barracuda and Cuda

• Pair of CNC-cut frame connectors (set of 2)
• Front and rear torque boxes (set of 4)

The frame connectors are CNC-cut and engineered for strength, so they add stiffness without heavy, thick plate. Meanwhile, the four torque boxes spread the force at the front and rear suspension mounting points. Some pieces fit the factory locations, while others reinforce known weak spots.

A stiffer chassis lets the suspension do its job. Springs, sway bars and shocks all work better when the body stays square. So the car launches straighter, turns in sharper and feels more solid on the road. Also, buying the Level 1 chassis stiffening pack for the 70-74 Barracuda and Cuda saves you money over purchasing each piece separately.

Fitment

It fits 1970 through 1974 Plymouth Barracuda and Cuda E-bodies. The Challenger rides on a longer wheelbase, so it needs its own frame connectors and kit. Not sure which pack your car needs? Call us before you order and we will help you pick the right one.

Early 1970 cars: please call before you order if your car is an early-built 1970. We have had reports of fitment issues around the torque box area on some of the earliest cars.

Installation

These parts weld in. We recommend an experienced shop, with the car supported at ride height so the chassis is not twisted while welding. Before welding, remove undercoating and seam sealer at each weld area.
