Features & DetailsHigh Performance, Less Effort: The efficient gear ratio enables the torque multiplier to deliver up to 6800 Nm (for BD-64D-A and BD-78D-C) or 4800 Nm (for BD-58D-C and BD-58D-A) of output torque. This allows you to easily loosen even the most stubborn nuts quickly without the need for any additional power tools.Built to Last and Secure: Made of robust alloy steel, ensuring wear resistance and durability in various environments. The lever design generates powerful force and reduces the risk of breakage, even when used on heavy equipment.Portable and Practical: Lightweight and compact tool case with a durable plastic shell, making the torque wrench multiplier easy to store and transport. Whether you're working in a garage or outdoors, it's convenient to carry and use.Multiple Sizes: The heavy-duty torque multiplier wrench set includes a 1" drive torque wrench and various sockets. The BD-64D-A and BD-58D-A models come with eight sockets: 21# square, 24mm, 27mm, 30mm, 32mm, 33mm, 38mm, and a 1" adapter. The BD-78D-C and BD-58D-C models come with four sockets: 21# square, 33mm, 38mm, and 41mm. These versatile sets meet various dismantling needs and are suitable for removing stubborn lug nuts on commercial or agricultural vehicles' wheels, including trucks, buses, RVs, semi-trucks, and more.Anti-slip Textured Handle: Provides additional friction when gripping, preventing the handle from slipping out of your hand, especially in wet or sweaty conditions. The unique textured pattern increases friction upon touch, enhancing grip stability for safety during use.SpecificationsModel: BD-64D-AItem Model Number: BD-64D-AMaterial: High-Quality Alloy SteelSurface Treatment: Spray CoatingTorque Input End Square Head Size: 1"/25.4x25.4mmTorque Output End Square Head Size: 1"/25.4x25.4mmMaximum Output Torque: 6800 N.mTorque Multiplier Ratio: 1:64Case Sizes: 15.75 x 3.74 x 12.40 in / 400 x 95 x 315 mmNet Weight: 25.35 lbs / 11.5 kgModel: BD-78D-CItem Model Number: BD-78D-CMaterial: High-Quality Alloy SteelSurface Treatment: Spray CoatingTorque Input End Square Head Size: 1"/25.4x25.4mmTorque Output End Square Head Size: 1"/25.4x25.4mmMaximum Output Torque: 6800 N.mTorque Multiplier Ratio: 1:64Case Sizes: 15.94 x 4.53 x 8.66 in / 405 x 115 x 220 mmNet Weight: 23.81 lbs / 10.8 kgModel: BD-58D-CItem Model Number: BD-58D-CMaterial: High-Quality Alloy SteelSurface Treatment: Spray CoatingTorque Input End Square Head Size: 1"/25.4x25.4mmTorque Output End Square Head Size: 1"/25.4x25.4mmMaximum Output Torque: 4800 N.mTorque Multiplier Ratio: 1:58Case Sizes: 14.96 x 3.74 x 8.46 in / 380 x 95 x 215 mmNet Weight: 19.84 lbs / 9 kgModel: BD-58D-AItem Model Number: BD-58D-AMaterial: High-Quality Alloy SteelSurface Treatment: Spray CoatingTorque Input End Square Head Size: 1"/25.4x25.4mmTorque Output End Square Head Size: 1"/25.4x25.4mmMaximum Output Torque: 4800 N.mTorque Multiplier Ratio: 1:58Case Sizes: 15.75 x 3.74 x 12.40 in / 400 x 95 x 315 mmNet Weight: 25.35 lbs / 11.5 kgPackage ContentModel: BD-64D-A1 x User ManualSockets (21# Square, 24mm, 27mm, 30mm, 32mm, 33mm, 38mm, 1" Adapter, 1 x Extension Socket)1 x Torque Multiplier1 x Extension Bar1 x Rocking Handle Bar1 x Plastic Storage CaseModel: BD-78D-C1 x User ManualSockets (21# Square, 33mm, 38mm, 41mm)1 x Torque Multiplier1 x Extension Bar1 x Rocking Handle Bar1 x Plastic Storage CaseModel: BD-58D-C1 x User ManualSockets (21# Square, 33mm, 38mm, 41mm)1 x Torque Multiplier1 x Extension Bar1 x Rocking Handle Bar1 x Plastic Storage CaseModel: BD-58D-A1 x User ManualSockets (21# Square, 24mm, 27mm, 30mm, 32mm, 33mm, 38mm, 1" Adapter, 1 x Extension Socket)1 x Torque Multiplier1 x Extension Bar1 x Rocking Handle Bar1 x Plastic Storage Case
