Level 2 Chassis Stiffening Kit 70-74 E Body Dodge Challenger

This Level 2 stiffening kit fits the 70-74 E body Dodge Challenger. Level 2 starts with frame connectors and four torque boxes, the same parts as a Level 1 kit. Then it adds inner fender braces and a front lower core support brace. As a result, the front of the car stops flexing too. Because the whole structure works together, the car moves as one piece instead of twisting.

What’s in this Level 2 chassis stiffening kit for the 70-74 E body Dodge Challenger

• Pair of CNC-cut frame connectors (set of 2)
• Front and rear torque boxes (set of 4)
• Inner fender braces for the front (set of 2)
• Front lower core support frame brace

The CNC-cut frame connectors tie the front and rear rails together. Meanwhile, the four torque boxes spread force at the suspension mounts. Up front, the inner fender braces firm up the fender structure, while the core support brace ties the front rails together. Some pieces fit factory locations; 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 2 chassis stiffening kit for the 70-74 E body Dodge Challenger saves you money over purchasing each piece separately.

Fitment

It fits the 1970 through 1974 Dodge Challenger. The Plymouth Barracuda and Cuda use a shorter wheelbase, so they need different frame connectors and their own kit. Not sure which kit 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.
