High Performance Serpentine Belt Idler

PLEASE NOTE: As of 2025, the idler pulleys no longer have the "gates" or shoulders on the sides, This was added originally to help with belt walk, but ended up causing more issues than it solved, so they were removed on all batches made after Jan1, 2025.  These 6061-T6 billet idler bearings are a big upgrade from the plain stamped steel versions that the OEM uses. Traditionally the 89052 idler from Dayco was the go-to for 6 rib applications, and we used the Continental 49102 for 8 rib configurations and the 49111 for 10 rib. The issue was cost, lead time, and quality. We decided to step up and make our own in house, so that none of that would be an issue any longer. There are a few options for these idlers, so pay attention.  The overall design of the HD/SD pulley will accommodate either a 6 or 8 rib belt width. You have a bit more "wiggle room" in 6 rib. The 10 rib will fit anything 10 ribs or less (obviously). You MAY have to shim the idler back or forth, depending on what idlers you
