All Concept One pulley systems now feature a new, upgraded alternator fan. The newly designed fan features a fin design and outperforms GM OE and other aftermarket alternator fans. Made of billet aluminum, it is CNC-machined for precision. The new fan is available on all Chevy and Ford kits.

“We redesigned our alternator fan because we found the increase of electronics on vehicles was putting more pressure on the alternator which requires better cooling,” said Kevin Redd, Concept One co-owner.
