Quick Tech: Box Your Arms

So you want the strength of boxed and reinforced suspension parts but don't have the reinforced wallet to make it happen with trick new parts? Or maybe your particular ride does not have an aftermarket beefed-up control arm available. Here's the solution: Box up your stock control arms! Here, we sourced a pair of original GM lower control arms from our '65 Chevelle project. That car got new stuff, so we grabbed the extras, which happen to fit our 1968 Buick Riviera project. Which, by the way, is one of those cars that has very little in the aftermarket as far as parts are concerned, so we were happy to find that we could make Chevelle parts fit. Follow along as we media blast, then weld up our control arms for extra-strength. And although we didn't show it, they'll get new bushings someday as well.

Bill,

We will replace the bushings at some point. The Riv's suspension design is not a triangulated 4-link, it's a 3 link with 2 lowers, and upper arm, and a panhard bar, so we could replace the rubber bushings with a different substance without worry of binding.
