ROCK SOLID FOR OVER 60 YEARS!Hedman Hedders and Trans-Dapt Performance Products have served the automotive performance Aftermarket, and the world's "Gearhead" in general, for more than 60 years. Our founders, Willie Garner and Bob Hedman, were cogs in the machine that launched the Speed Equipment Maarket Association, now known as SEMA (Specialty Equipment Market Association), and we have participated in every SEMA Show dating back to the very first official show back in 1967.

With a history that dates back to the industry's very beginning, The Hedman Performance Group wouldn't let the absence of a live, in-person SEMA Show, keep us from meeting one-on-one (albeit vitually) with speed shops, warehouse distributors and e-tailers, to discuss how our iconic brands can help grow thier business, and offer products that their customer want.

ALWAYS HERE TO HELP OUR DEALERS, SHOPS AND BUILDERS! While the Hedman Performance Group has live, knowledgeable phone personnel to answer dealer and builder questions between 8am-4:30pm M-F, The HP Group SEMA360 microsite has new product information, and content that is not yet available anywhere else on the planet, and additional content to help you find out more about our family owned company and all we have to offer.
