      vintage air / kwik performance belt slip help

      Hey guys.

      71 Chevelle.
      LSA. 700hp.

      Vintage air
      kwik performance pully/tensioner...

      belt keeps slipping.
      The kwik pully
      is 4 rib. The other end/pullies are 6rib.

      Therss no guide. So when I slam on it
      belt spins off.



      I called kwik. He’s like we don’t make a
      6rib. Use a shorter belt..

      wtf..

      options ? Ideas. Help.

      Is this the low mount compressor kit where the compressor is in the stock location? If so, there are three versions of that kit, depending on which balancer spacing you have. The LSA should use the "Corvette spacing" which is Kwik part number K10355. These kits are designed to run on the OEM compressor grooves for the crank pulley, which are only four groove. Yes, the compressor has a six groove pulley, but the crankshaft will only support a four groove, so that's what you have to use. There is no need for a guide on a serpentine belt, but all of the pulleys must be aligned and running true to each other. If the belt is actually slipping, and the tensioner has plenty of pressure on it (at least 25% compressed), you may have some other problem, such as excessive head pressure on the AC system. Make sure your fans are running when the car is sitting still with AC on, regardless of engine temp.

      Hope this helps.

      Its not slipping. Its a misalignment issue. I have had too many of them squeal at me like it was slipping. Change belt great for a couple hundred miles, then goes to squealing again. My opinion, throw it in the trash and install a Holley bracket.

      Mine works perfect. I had to stall a washer on the top pulley to spacer it put some and it’s been great ever since

      Multiple people have had the same issue with kwik. I solved it temporarily by shimming the bottom of the pulley, then permanently by switching to the Holley bracket. Much, much better pieces and far more solid than any of these plate-and-spacer types of brackets.
      When I mentioned this issue to kwik at LS Fest they didn't really seem to care.
      Edit - saw MR already provided the best solution, throw it in trash.
