The Hughes Performance 2000 Stall Series Ford C4 torque converter (MPN 41-20) gives street rod builders a measured step up from a stock factory unit without pushing stall too high for daily driving. Hughes Performance built this converter for the enthusiast who wants slightly quicker launch and better engine matching on a 1970-81 Ford C4 transmission. The 2000 stall point keeps the converter civil at idle and around town while letting the engine reach a stronger spot on the torque curve before the converter couples. It's a sensible upgrade for mild small-block builds running the classic C4 automatic.
This converter measures 11 inches in diameter with a 10.5-inch bolt pattern and a 26-spline input, matching the 1970-81 Ford C4 transmission spline count and flexplate layout. Hughes Performance uses silicon brazing on the internals for added strength under load, needle bearings in place of stock thrust washers for better durability, and stator modifications that increase torque multiplication off the line. Those stator changes are what let a converter raise effective launch performance without simply running a looser stall. The 26-spline input shaft engagement is specific to the C4 family, so verify your transmission generation before ordering. Pair it with a matching C4 transmission dipstick and the right Ford flexplate for a clean install.
A 2000 stall converter suits a Ford running a mild cam, a stock or slightly built short-block, and a rear gear in the street range. It wakes up off-idle response without the loud, slipping feel of a high-stall race converter, so it stays comfortable for cruising and highway driving. Builders refreshing a 1970-81 C4 during a rebuild commonly drop in a fresh converter at the same time to reset wear surfaces. Browse the rest of our drivetrain parts for the C4-specific hardware, gaskets, and shift components you'll need to finish the job.
It lets the engine spin to roughly 2000 before the converter fully couples and transfers power. That puts the engine in a stronger part of its torque curve at launch, improving off-the-line response. At 2000 stall it stays mild enough for daily street driving without the loose, slipping feel of a high-stall race converter.
This converter is built for 1970-81 Ford C4 transmissions, with a 26-spline input shaft engagement and a 10.5-inch bolt pattern. Confirm your C4 falls within that generation range and uses the matching spline count before ordering, since earlier C4 units can differ.
The body measures 11 inches in diameter with a 10.5-inch bolt circle for the flexplate. Match these dimensions against your flexplate and bellhousing clearance before installation.
Hughes Performance uses silicon brazing on the internals for strength, needle bearings instead of stock thrust washers for longer life, and modified stator vanes that increase torque multiplication. Together these upgrades hold up better under repeated launches than an unmodified factory converter.
