underdrive pullies make your water pump run slower making your motor run hotter. they also make your alt spin slower. ive seen some people complain of alt voltages as low as 12 amps when they used to run 14 strong. not good if you have alot of electric parts such as electric fans. theres better mods out there for the money.
old mod list: H/C/I/N/E/G 408
new mod list: 5.3, gears/posi, mufler and tune : (

The $$$ are better spent elsewhere.
