5203 Lower Boxed, OE Length, 77-96 GM B-Body

Looking to give your 1977-1996 GM B-body, like your Chevy Caprice, Buick Roadmaster, or Oldsmobile Custom Cruiser, a little extra edge? QA1's Boxed Trailing Arms (Rear Control Arms) are just what you need. These trailing arms eliminate the flex and bind of stamped steel arms while delivering serious performance enhancements to your ride.

BUILT TO LAST

Our trailing arms are made from larger rectangular tubing, giving them the strength to handle whatever you throw at them. Plus, they come with fully capped radius ends, keeping dirt and debris out so you can keep cruising without worries. The black powder coat finish not only adds durability but also gives that clean, factory appearance that every classic car enthusiast loves.

IMPROVED HANDLING FOR EVERY DRIVE

Whether you're hitting the strip, cruising the streets, or carving corners, these trailing arms are designed to reduce suspension deflection. That means you’ll get a sharper, more responsive ride with less wheel hop. Plus, with reinforced sway bar mounting holes, you can easily keep your factory-style sway bar in place, making these arms stronger than those old stamped steel ones that tend to flex.

A QUIET, COMFORTABLE RIDE

We know that you want performance without sacrificing comfort. That’s why our boxed control arms come assembled with greaseable polyurethane bushings. These bushings are designed to reduce noise and vibration, giving you a smooth, quiet ride every time you hit the road.
