Stock locking torque converters stand no chance in high-performance diesel applications. Get rid of this potential point of failure by switching to the BD Diesel Hi5 Torque Converters! Increasing torque holding capacity means having multiple friction surfaces and being equipped with heavy-duty parts.

When you hold on too long to your stock torque converters and wait for failure, the turnaround time for non-rebuildable torque converters is fairly long, not to mention being expensive. Dodge these bullets with the rebuildable BD Diesel Hi5 Torque Converters, which solves the problem by increasing the surface friction surface count to five and adding six additional flexplate bolts to reach a total of twelve.

This large diameter frictional design reduces clutch slippage while heavy-duty springs absorb NVH. Moreover, it has self-centering teeth that decrease wear and chatter, while added durability comes in the form of the fully-machined pistons, billet cover, steel roller thrust bearings, new sprag components, and the furnace-brazed turbine/impeller fins. Benefit from convenient servicing and impressive ruggedness with the BD Diesel Hi5 Torque Converters!

What sets BD Diesel Performance from other brands is that it is dedicated to providing regular and enthusiast diesel vehicle owners with competitive performance parts in both quality and price. The brand started in 1972 when Valley Fuel Injection Ltd. started offering services to the public.

Nowadays, Valley Fuel and BD Diesel Performance operate as one and direct over eight specialty divisions that serve specific vehicle applications: Fuel Injection Calibration Department, Exhaust Brake Manufacturing, Electronic Circuit Design and Assembly, Transmission and Torque Converter Design and Remanufacturing, Turbocharger Design, Installation, and Research and Development. All of these departments are housed in a 65,000 square foot high-tech facility manned by specialists and highly-trained individuals to ensure the manufacturing process is a seamless one.

Once BD Diesel Performance got its big break in the market after releasing the first exhaust brake for the then-flourishing pickup truck craze, the brand rode the wave of momentum and released a barrage of turbo, fuel, transmission, exhaust, and electronic solutions to give customers a wide range of options to choose from.
