Pioneered by California Pony Cars, our Mustang T5 transmission crossmember bar design is the original tubular steel solution trusted by classic Mustang enthusiasts for over 40 years. Many competitors have copied this design, but our crossmember stands apart thanks to superior heavy-gauge materials, expert fixture welding, and an industry-leading powder coat finish that resists corrosion and wear. We use only the highest quality materials — avoid cheaper copies made with thin steel, poor welds, and inferior coatings.
Engineered specifically for World Class and Tremec T5 5-speed manual conversions, this crossmember bar is built to OEM specifications and designed without a parking brake bracket, just like the original factory design. It accommodates the OEM-style rubber/steel transmission insulator (C4DZ-6068-A / TRA-650-521), ensuring a direct fit with no vehicle cutting or drilling required.
