Having trouble with one being slightly longer than the other and not getting an even tightness. Someone said you can request a matched pair (having the same lot number), but I just called Napa and they had no idea what I was talking about. Is it still possible to do this or do parts houses not understand anymore that some cars used to take a pair of v belts?

NAPA did carry matched sets.Ive bought several years ago.You need to find someone that can read a book instead of a computer.They are called matched sets.I know Advanced used to carry them also.What are they for?My kid works at Advanced maybe he can get a part no.Rocky

I tried to get a set for my 66' Coronet a couple years ago and was told there was no such thing I finally found a Carquest that had someone who knew what I was talking about. He said that it was a thing of the past as they are made to "exacting" standards and are all the same. I protested but he insisted all would be well. So I ordered them and they wouldn't work. One was flopping around really bad and the other nice and tight They took them back and I found myself at a Advanced Auto parts next. He ordered in like 5 or 6 of them and I picked the two that measured up similar on the belt measurer they had. Not perfect but close. Haven't had any issues with them. Sad thing is not 10 years ago was able to get them no problem for my 69' (matched set) Good luck on your search

JB,...matched sets are still available, most parts store dummies have no clue what a matched set means,....when a belt is made, it starts life as a long tube that gets turned (cut) in to the desired V rating (width and profile) numbers are stenciled along the belt in a progressive series along the width, ...example 33345 and 33346 are matched, 33345 and 34478 are not, it was cut further down the tube, which may be smaller or wider in diameter,....the BS line that all belt are now built to exacting standards is BS,....find a parts store that can supply your request

All the belts should have a lot number on them. Find 2 with matching lot numbers and you should be good to go. Automotive V-belts in matched pairs would be a thing of the past with everything having serpentines on them now.

May be the case with some but not with Gates.Just went through the same thing. What I was told:
All of our v-belts a formed ground (cut) and are within 1/,1000 of inch tolerance from each other. When the dealer told you all belts are matched, he was telling the truth. With that said, a few years ago we changed the design of the inside cogs of the belts. Please see if the cogs match each other. You will also see a code in red ink on the belt (example:238SS). That tells the run date and location. If those numbers are close or the same, that means the belts were mfg on the same spool.

These were Duralast 15610's. I don't know who makes the belts for AZ, it wasn't clear on the band. This is a bit longer than stock 70 383 with a/c because I'm running a GM case alternator that is swung out a bit more to clear the head. These belts are a touch wide to sit into the grooves as nice as I'd like but I think that is the price paid for the longer belt. It was _ok_ without the a/c on, but 1 really flopped with the a/c on, and it kicked that belt when I went racing last month. Been running with just the 1 belt but it has started to squeal some with the a/c on, can't hold both it and the alt drawing power for the EFI ecu and fuel pump apparently.

ive been in the parts bizz for 14 years now . it used to be really easy to order matched sets. not so easy anymore. what i usually have to do is order 4 or six of the same part number to get 2 that are matched. now quit giving the poor parts people crap about it. and just so we are clear, most of us can read .

well that was an extremely painful conversation over at napa, even armed with all that data from the gates site the computer jockey at Napa was completely unable to grasp what I was trying to get at.

Goodyear has a line of belts called The Matchmaker that hold the same length tolerance no matter where they're made.
Our local NAPA warehouse will send somebody "upatairs" to visually match mold numbers when matching belts are ordered.
