    Pulley swap

    The pulley swap is hard to do if you do not have an impact wrench.

    Shiny!

    Tried the black steel pulleys first. Crank shaft pulley cracked twice. Spent a little extra for the aluminum and install was flawless. Dresses it up a bit too

    Bang for you buck

    Easy to install if you have the radiator Out of car and a torque gun handy . They say kit comes with 4 pump bolts? Wrong the bolt are for the new crank pulley can't use old bolts heads hit inter dimension.

    Wait and See

    Quality seemed a little less than the previous pulleys I had in (March pulleys). But I'll try them and wait and see.

    Awesome gain

    Would have taken less time but I put on a march alternator bracket that deleted the smog pump. Overall easy fit crank pulley is deep and is hard to tighten bolts but very doable. No charge problems and the engine definitely revs up faster

    Good Shiznit

    Good product, the pulleys brighten up the engine bay and add a little something you can feel. To pull the alternator and crank pulley You will need to use a impact gun and probably need to pull out your radiator for the impact gun to fit, but this gives you the added bonus of doing a nice coolant flush and a opportunity to rinse out that old radiator if its still stock like mine is.

    Feel the difference.

    These things are a great HP investment. For cheap you can increase HP and get a noticeable difference. If you are slightly mechanical, you can install yourself.

    great!

    the part were just as the picture shown, make sure to take the alternator pulley to autozone, cause you will not be able to take it off, you will need an impact gun to get it off..

    Its been about 2 months since I got them and I can still feel a pep in my stangs step. I recommend this pulley set for someone with a budget like myself who wants to give their stang a little extra power.

    BBK Aluminum Pulleys

    Easy to install, look good still need to add Billet Alluminum smog pump eliminator to complete the job to make sure I get the Maximum horse power out of these nice looking pulleys. My 93 GT dose run a little stronger and is quicker in response to the gas peddle since I installed a new water pump, aluminum radiator, 9mm spark plug wires, auto lite plugs, Accel kap and rotor and these BBK Under Drive Pulleys which to me about 9 hours to install. These very minor upgrades have made a noticeable difference in the overall performance of my 5.0 and I kinda get a little ax-sited thinking about how much nicer it is going to sound and how much stronger it will run when I finish my mild transformation when I add a mac exsaust, a bama chip, a billet smog pump eliminator, a cold air cleaner and some sub frame connectors which should add up to 50 horse power to the original 210 horse 5.0 GT power plant. I found this GT all original unmolested rust free car in November 2015 and just started to drive it this spring and I like a lot and enen though the red paint has faded and the clear is peeling not a mouth goes by with out someone telling me that they like my car and want to buy it, and I tell them it's not for sale.
