Stifflers, located just outside of Indianapolis, Indiana, the racing capital of the world, was started in 2010 by founder and head engineer, Brian Figg.

Racing and engineering are in his blood! The entire team here at Stifflers is made up of automotive enthusiasts that love what we do and what we are creating. It's not work when it's a passion!

Made in the U.S.A., the creation of all Stiffler's products, starting with design and testing, through the manufacturing process, to packaging and shipping, are completed here at our facility to ensure everything meets and exceeds Stiffler's high standards every step of the way. This is our commitment to our customers.

Because of this, we stand behind our products 100%. When you buy a Stifflers product, you are purchasing a highly engineered product that will fit and work right the first time, every time. Trust and quality are what we stand behind and build into every component we make. Contact us today for more information on our custom auto parts for Mustangs and F150s.
