The Boss Hog 25113 Street Bandit Series Torque Converter is built for Ford C4 transmissions with a 26-spline input shaft and small bellhousing configuration. With a stall speed of 2800–3200 RPM, this lightweight unit is designed for high-response street performance, especially in vehicles with choppy cams and lightweight builds.
Precision-engineered with a 9.6" core, 10.5" bolt circle, and CNC-machined components, this converter delivers fast engagement, reduced rotational mass, and reliable power transfer. It's digitally balanced, leak-tested, and made in the USA for quality you can trust.
Upgrade Tip: For power adder setups (nitrous, supercharger, turbo, trans brake), choose the Outlaw Racing Series converter.
