I am very pleased with the quality and appearance of these UD Pulleys. Installation was easy and provided noticable MPG Gain and smoother idle. A little more pep i the 3k RPM Range.

Install of pulleys went as planned on my 1992 Chevy 5.7 truck. Only on minor problem. The instructions from BBK said the belt required for this kit was 91.5". No way that belt fits. I called BBK and asked them if this pulley set up was on a truck with or with out a/c, I thought this maybe the difference in the belt size. They said that they didn't have a record of the the vehicle that the pulleys were tested on. So, I ended up returning it to my local NAPA store and got one two inches longer and it mounted right up.

After install, I notice a good increase in acceleration and horse power. with my air raid cooled air intake throttle body spacer, full exhaust and a few other mods it makes a great addition. You will not notice a huge difference in performance if this is the only mod you plan on doing to your vehicle, but teamed with the right parts you will definitely feel the performance and power!

So far im loving the pulley's. for $130-160 for atleast a 8hp gain the price is hard to beat. only thing bad i had installing my set was the bolt that goes to the crank pulley was not the correct thread pattern, but that was easy enough to overcome. nice finish too them aswell.

i FOUND A NICE INCREASE IN LOW AND MID-RANGE POWER AFTER INSTALLING. AT FIRST I WAS A LITTLE DISAPPOINTED DUE TO A FRIEND OVER-HYPING WHAT TO EXPECT. BUT ALL-IN-ALL THE PULLEY'S WERE WELL WORTH THE MONEY. **MOREOVER, THEY DO INSTALL IN ABOUT 30 MINS. JOHN TWIN FALLS, ID.
