2011-2012 GT500 Performance Upgrades & Parts


The 2011-2012 Shelby GT500 is a badass ride as is — but when you add 2012 GT500 performance parts from Lethal Performance to the mix? Let's just say we can make some pretty sweet improvements. The 2011-2012 suspension system can be easily upgraded, but there's a ton of power to be gained from simple bolt-on modifications as well. Throw in a custom tune for an HP increase by up to 40rwhp, plus a set of long tube headers or an offroad X-pipe for another 15-30rwhp on top of that.

But what 2011 GT500 performance upgrades are gonna make the Shelby GT500 really Lethal? A small supercharger pulley and a custom tune will take you up to 90rwhp over stock. And if you want, even more, try out our aftermarket superchargers and turbo upgrades — they'll let you make anywhere from 600rwhp to 1300+rwhp! Our most popular supercharger upgrade is the Whipple 2.9L kit. We're guessing you'll want to try it out.

As they say, with great power comes great responsibility. As you upgrade your Shelby's power with premium 2011 Shelby GT500 performance parts, you'll also need to install supporting mods that can safely handle the power levels you're aiming for. To make your setup work, you'll need a proper fuel system, injectors, throttle body, intake, and exhaust.
