What is the main benefit of installing subframe connectors?

Subframe connectors tie the front and rear subframes of your vehicle together, creating a more rigid chassis. This added stiffness helps to reduce body flex, which can improve handling, reduce rattles, and make the entire car feel more solid.

Do I need to cut my floorboards to install these connectors?

No, these Hotchkis subframe connectors are designed to install without requiring any cutting or modification to your Challenger's floorboards, simplifying the installation process.

What material are these subframe connectors made from?

They are fabricated from strong rectangular steel tubing measuring 1.5 inches by 2.5 inches, with a substantial .120 inch wall thickness for added rigidity.

About this part

Product Details

If you're restoring a 1970-1974 Dodge Challenger, especially one that's seen a few decades or is getting a more powerful engine, you'll want to address chassis flex. These subframe connectors from Hotchkis are designed to tie the front and rear subframes together, creating a much more rigid unibody structure. This added stiffness not only improves how the car handles during spirited driving but also helps to reduce those annoying body rattles that can develop over time.

Hotchkis builds these connectors from strong, 1.5-inch by 2.5-inch rectangular steel tubing with a wall thickness of .120 inches. They're MIG welded for solid joints and then finished with a gloss black powder coat to resist corrosion and look good. A key benefit is that they install without needing to cut or modify your floorboards, making the process much simpler for your restoration project. This is a popular addition for E-Body Mopar enthusiasts looking to firm up their classic Mopar.

This kit includes both the driver and passenger side connectors. They are a direct bolt-on addition that makes a noticeable difference in the overall feel and stability of your Challenger. If you're looking to get the most out of your suspension upgrades or just want a tighter, more solid classic car, these subframe connectors are a solid choice.
