ATI Serpentine Conversion Pulley Kits

ATI serpentine conversion pulley kits contain everything you need to convert your stock 6-rib serpentine belt to an 8 or 10-rib. If you are requesting more boost, causing your 6-rib belt to slip, then these kits are for you. The wider 8-rib belt gives you more belt surface, which can create more boost without slippage. ATI also offers a 10-rib kit for those who need even more boost. These conversion kits include a damper, a power steering pulley, a tensioner with a bearing, and an alternator pulley.
