The 2011 to 2014 Mustang GTs are not lightweights. They're big, heavy muscle cars, which becomes a problem if you want to maximize your Pony's handling abilities. That's where our selection of Mustang K-members come in. These awesome chassis upgrades replace your Mustang's big, heavy OEM stamped steel K-member with tubular chromoly alloy designs which are much lighter than stock while being more rigid. The end result is better weight distribution between your Pony's front and rear end as well as reduced chassis flex in your Mustang's front end, both of which provide a huge improvement in handling. Some of these K-members even have lowered motor mounts to allow you to drop large supercharger systems or custom turbo kits onto your Mustang GT's 5.0L Coyote V8 without needing to worry about clearance issues. After you're through with our Mustang K-members, take a look at our Mustang suspension packages, Mustang control arms, or our Mustang wheels and tires.
