When you drive your car to the limit the chassis flexes and twists causing sloppy unpredictable handling characteristics. One of the simplest ways to make your car handle better is to add reinforcement to the chassis. GMC Sierra Subframe Braces do just this. They connect crucial stress points in the chassis, such as suspension pick-up points, to the rest of the under carriage to add strength, spread the load and reduce unwanted flexing. The result is crisp predictable handling, better corner speed and improved overall performance. Whether on a twisty road or on the race track, subframe braces are one of the best single modifications you can make to improve your cars handling.

If you are running a high-horsepower engine, the power alone can cause the chassis to flex and twist. Over time too much chassis flex will cause metal fatigue and eventually total failure. You do not want this to happen as it is extremely dangerous! GMC Sierra Subframe braces are a great way to combat the torsional flex caused by a powerful motor. Many different styles of subframe braces are available but our general rule of thumb at Andy's is the stiffer the better. While you can buy just a front or rear subframe brace, adding both to your car will make the handling much more predictable and give the car a lot more added strength.

Q: What are subframe braces? Why buy them?
A: A subframe brace is a structural device that links the lower portion of your vehicle’s suspension to provide increased rigidity and reduced deflection to improve handling, vehicle control, and safety. Most modern rides rely on subframes to attach the suspension components to the chassis. These subframes can twist and deflect under harsh driving conditions causing sloppy and unpredictable handling characteristics. On the track this can mean valuable seconds, but on the street it can be a safety hazard as well. By firmly connecting and reinforcing your suspension components with a subframe brace you will have more predictable handling which will improve your confidence and help keep your vehicle both safe and fast as you drive down the road. In addition the added strength of a subframe brace can improve the lifespan of suspension components and the overall reliability of your ride.
