Unorthodox Racing PS681 Pulleys - Accessory Pulleys
Power Steering Pulley
64% Lighter Than Stock
Unorthodox Racing Ultra Series Accessory Pulleys are available
individually as well as in our Ultra Series pulley sets. Accessory
pulleys for most applications are stock diameter. We do not
underdrive with our accessory pulleys for two reasons. Our main
reason is because all our underdriving is done with our crank
pulleys. This provides maximum weight loss at the crank where most
of the horsepower gains are found. Second, not much horsepower is
gained from extreme underdriving. It is important to keep charging
systems, air conditioning, power steering, and water pumps moving
fast enough for every day driving.
Since our accessory pulleys are the same diameter as the stock
units, you may install our Ultra Series crank pulley as a first
step. Then, at a later date, you may purchase our accessories and
install them without having to change belts again (on most models).
For certain applications underdriving ratios are modified with the
accessory pulleys when underdriving is not feasiblewith the crank
pulley. In these cases accessories and crank pulleys are only
available as a set and are not available individually.
Our Ultra Series accessory pulleys cover most of the same
applications as our pulley sets.
