If there's one thing certain about a Muscle-era Mopar, it's that the unibody construction allowed the body to flex and "give," which isn't a problem when it comes to daily driving. But you take into account that there isn't a Mopar out there that hasn't done everything except the speed limit and nice, calm, pleasure cruising, that flex just got worse over time. In other words, at one time or another, every Mopar out there has had its muscle status tested.

Now that these cars are pushing a few years past the legal drinking age in most states, the years of flex and "give" have added up, and our car's body-much like many of our own-has begun to soften, so to speak. They (the cars in this case) flex more than they used to, unlike ourselves, and this causes a myriad of other issues for our cars. Add to it that many of these cars have received engine transplants with more power, and it stands to reason that something needs to be done.

Hotchkis Performance has come up with their version of a chassis stiffening device (i.e. sub frame connectors) that can make a real difference in your Mopar. The connectors are designed to be used in conjunction with their complete suspension kit, but just adding the connectors is such a good idea in itself, we'll cover that now and show you how their suspension goes in and works next time.

We'll let you know up front that to properly install these connectors you will either need a welder or at least access to one. Welding the connectors in only took a couple of hours, and it's definitely worth it.

One last thing to keep in mind is that under no circumstances should the connectors be installed with the suspension unloaded (i.e. on a two-post lift). In the following pictures, we used a two-post lift only to mock up the fitment and for ease of taking pictures. Always install connectors like this with the car sitting level on all four wheels.
