Remember, the 420a also came in the Avenger/Sebrings in the same configuration

RE: UDP Install Write Up?
Original poster Mopar McNeer
I just got mine in the mail today. I'll be installing it this week/weekend. It appears to be very nicely constructed and should work great...
The belts you need (according to the instructions)
Gates brand : Alt: K040320 (32.75 inches or 830 mm)
P/S-A/C K050490 (49.5 inches or 1255 mm)
But I should also note--that when my car is at idle (or idling at a stop with my foot on the brake), the stereo (amp and subs) draws enough to dim my lights (drops down to 12v)--where it did not before. Obviously the alt is underdriven (most noticable at idle), So I gave up some idle power, but once I get rolling--I have no problems and the volts stay at about 14v and no dimming. I just turn my tunes down to keep from looking like that dumb *** whose lights dim (greatly) with each hit of bass....
****And as I posted in a post above--it will require new alt belts and new A/C-P/S belts. Below is a pic for comparison between the UDP and the factory one....the difference is easy to notice.

RE: UDP Install Write Up?
Bro, it's on the crank. The write up is in a Haynes/Chiltons manual on removing the Harmonic balancer/crank pulley. The UDP is the only pulley with two accessory belts on it, just like in the pic.... It's not hard and there's no shortcuts. Look at your pulley, plan your attack and go for it. If you're that worried about it, take it to a shop and let them do it. Chances are, they can get the belt replacements for you too.
