Product Description

RB billet underdrive pulleys:
Underdrive pulleys reduce the speed at which engine accessories, like the alternator, water pump and power steering, are driven. By slowing these pumps down, less power is drawn from the engine, freeing up horsepower for better performance and efficiency. This results in quicker throttle response, improved fuel efficiency, and lower engine load, making them an ideal upgrade for enthusiasts looking to optimize power without sacrificing reliability.
Results will vary between 1-5hp.
For motorsports enthusiasts, slowing the pumps down can be useful in hi-rev situations.
