    Underdrive Pulleys for a C5

    Im looking to get some underdrive pulleys installed on my C5. Has anyone installed underdrive pulleys? Are they easy to install? Are they worth it? Any suggestions on where I can buy some, and about how much$ they are? Thanks

    well im gonna get some shorty headers eventually, I want longtubes but as i understand it, those are illegal in CA my home state. I hear shorties only give u about 10 horses, and pulleys around 12-15, but shorties are about 1000 plus installation, unless i do the installation myself.

    my next two mods at this point are prolly gonna be high flow TB and an X pipe

    They have a harmonic balancer, part # 941020 for $248. I'm looking to install a pulley kit also. I think SLP makes a kit too.
    www.slponline.com About $236

    I did mine about 2 weeks ago your going to have to lift the car lower your suspention
    remove the rack and loosen the engine cradle and wedge it in the front so you have enough
    room to remove the pully its a pain best thing is to have it done out

    If you do a cam, then do pulleys at the same time. Just doing pulleys alone...not worth it.

    Exactly what I was going to say.

    You will not see much out of a pulley swap alone for it to be worth the cost and hassel of install.
