I took my belt back to GM today to get a shorter one. No luck. They cant get a belt by the length. The 5.3 a/c belt is 960mm long and it just does let the tensioner bottom out. Any ideas? Turns out, GM cant look up a belt for a LS1 powered 86 silverado with a 04 5.3 a/c unit and a balancer with extra groves machined in. Who knew???
The Orielly counter gods can find one for you.
Ya just go to a good parts store and they will be able to grab one shorter. Not that hard to do. I dont know why they did not at gm. They have various sized belts for diff applications. OOOOH parts guys got to love them LOL :bash:
The dealer only stocks factory original equipment parts. They wouldn't stock anything if they could get away with it.
Found one. A 37.2 inch 4 rib works. The Autozone store found one in about 2 minutes. Its not GM but it works fine. Anybody know what this belt fits? Its a Duralast 372K4. Really want the all factory GM look. Finally got the 5.3 A/C mounted and both belts on. Now time for the custom A/C lines. :cool:
Can't wait to see that bad ass truck on the street!
Good deal! I new these guys had you going in the right direction. BTW, GM/ACDelco belts are probably made by Gates anyways and they probably make the Duralast. :cool:
Hey Ryan, Here are the cross reference numbers if you have to have ACDelco.
ACDelco - 4K372
Gates -40372
Duralast - 372K4

I just want it like GM built it...Know what I mean?
But GM didn't build '86 Siverados with LS1's in em did they? :laugh: I'm just givin you a hard time, I understand what you mean, even if you are being a bit anal about it.
