Front spring hanger Reinforcing Plate

Installing a set of SS springs using the required front spring hangers on an E-body. I see there are reinforcing plates available. I don't need them for spacing purpose. However, is it recommended to use them on the backside of the front hanger for added reinforcement or are they not necessary?

I made my own? Thinking it adds strength?

The factory put them on the higher powered cars. Seems prudent to reinforce that area since there is so much stress there.

that being said, how does it help? its not load bearing, so unless your concerned with spring hangers pulling out, i don't understand what they do.

sometimes i just like overkill, one less thing to worry about

Silly me, I thought they were spacers to align the rear.

They are reproductions of the original stiffening plates but you can use them as shims to adjust the rear thrust angle if necessary. Works for either application.

I could see them as a benefit to drag cars with sticky tracks and gripping slicks that are trying to pull the hanger out of its mounting pocket. Not unlike a roll bar reinforcing plate that spreads load over a wider area.

I thought the load was more compression, especially for drag situations?

That is where we connect our subframe connectors, with a similar plate. Transfers the load and really adds to the chassis rigidity and control.

Its more of a sheer load on the front hanger, although it may be slightly compressive for the top two hanger studs and slightly expansive on the bottom two studs.

If you look at housing rotation on a launch, this pulls the front spring segment up, which pulls the spring eye up, which pulls the mounting bracket up, and because the mopar hanger is not symetrical, it pulls on the bottom studs and pushes on the top studs.

If you use a Cal-trac type device, it resists compressive loading, but this is due to the housing rotation around the axle that would compress anything mounted under the axle centerline.

The reinforcing plates are not a bad addition if you want them.
