JET underdrive pulley sets reclaim lost horsepower and mileage by reducing the drag placed on the engine to drive the accessories, such as the air conditioning, power steering, and water pump. The pulleys slow down these accessories to allow the engine to turn with less effort without any adverse effect on the operation of A/C, power steering, charging, or cooling systems. Installation consists of simple bolt-on replacement of the stock pulleys. Kits include pulleys, hardware, complete instructions, and part number for new serpentine belt as most kits will require use of smaller size belt. Belt is not included with kit. The number and type of pulleys will vary per application.

March Performance Chevy big block serpentine conversion kits simply bolt onto the front of any big block Chevy heads. Depending on the kit you choose, the alternator, A/C, and optional power steering will be either outward or mid-mounted. These pulleys are precision CNC-machined from solid billet 6061 T-6 aluminum to fit perfectly and handle high-torque and vibration. They are then clear powdercoated to eliminate polishing in those hard-to-reach places. These pulleys will not fracture like common cast pulleys, since they have high-tensile strength for much longer wear. The street rod ratio increases water flow and fan speed, which helps during critical low-speed driving. The kits are available with performance pulleys for increased horsepower, high water flow ratios for increased cooling, or mid-performance ratios for a combination of both.
