Trans Dapt Performance: Six Decades of Hot Rod Engineering

Few names carry as much weight in the American performance aftermarket as Trans Dapt Performance. Founded over 50 years ago, the brand got its start the old-fashioned way — with founder Willie Garner building and selling transmission adapters out of his garage. Word spread quickly about the quality of his work, and demand grew so fast that within just a few years, that humble garage operation had expanded into a sprawling 40,000-square-foot facility dedicated to manufacturing and fulfillment.

Today, Trans Dapt is part of the Hedman Performance Group, operating out of a 100,000-square-foot facility equipped with state-of-the-art CNC machining and CAD design capabilities. That kind of modern infrastructure, combined with decades of hands-on hot rod heritage, gives Trans Dapt a unique position in the industry: a brand that genuinely understands both the old-school builder and the modern performance enthusiast.

A Product Line Built for Builders

Trans Dapt earned its reputation as the go-to source whenever hot rodders needed a transmission, carburetor, or oil filter adapter. That reputation has only grown over the decades, and today the catalog spans a remarkably wide range of components for GM, Ford, and Mopar platforms. Engine swap hardware, throttle body spacers, motor mounts, oil pans, differential covers, chrome dress-up accessories, valve covers, and wire looms are all part of a lineup designed to help builders run stronger and look sharper.

One area where Trans Dapt particularly shines is drivetrain support hardware. Their transmission crossmembers are engineered to take the guesswork and fabrication out of custom builds and engine swaps. Whether you're dropping an LS engine into a classic GM A-body, swapping a Ford C-4 or C-6 into an early pickup, or doing a universal custom build, Trans Dapt offers both vehicle-specific and universal-fit crossmember kits designed to support standard and automatic transmissions across a wide range of frame rail widths.

Why Builders Trust Trans Dapt

What sets Trans Dapt apart isn't just product breadth — it's the philosophy behind the parts. From day one, the brand has been committed to offering a wide selection of quality components at a fair price. That means builders at every level, from weekend garage warriors to seasoned drag racers, can find the parts they need without compromise. Every component reflects decades of real-world performance knowledge, backed by modern manufacturing precision.
