Personally I love my UDP's and wouldn't go without them. The one thing you need to watch is that your alternator is not turning to slow with the under-drive pulleys and your battery is discharging during idle. If you experience this, an overdrive pulley for the alternator will take care of that. There are companies out there that make UDPs for the 4.0 Liter motor, but I'm not familiar with who. |
