Underdrive Pulleys 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. Installation consists of simple bolt-on replacement of the stock pulleys.
Fording a stream or climbing a steep grade—especially in hot weather—puts your off-roader's engine to the test. Your rig can handle it just fine, but what if there was an easy way to pull off more horsepower, torque and general engine performance without sacrificing anything? We would all like our 4x4 to rip across a rock garden without losing power and there is no way we are giving up air conditioning, power steering or air pumps. Making use of pulley kits, performance pulleys or similar replacement engine parts can make this dream a reality. At 4 Wheel Parts, we have belts, pulleys and other accessories for any engine type. Free Up Horsepower with Performance Pulleys Most aftermarket performance pulleys can redirect as much as 15 units of horsepower from an engine's accessories. They do this by turning these accessories at a slower rate than stock pulleys. This reduced effort in maintaining things like air conditioning, alternators and power steering frees up engine resources so that they can be involved in raw power. Many experienced off-roaders attest to the boost that this modest enhancement brings to their backcountry adventures. 4 Wheel Parts stocks everything you'll need to enhance your pulley system including accessory drive belts, serpentine belts, generator pulleys and A/C bypass pulleys.
