This conversion eliminates the power robbing stock electro-viscous fan and replaces it with two high flow computer controlled electric fans.  Converting to electric fans has been credited with gains ranging from 12-18 RWHP and fuel economy improvements of around 1 MPG.

This kit features three relays, which allows for quieter operation. This harness will bring both fans on at half speed for low, and both fans on at full speed for high. Fits 5.3L and 6.0L Trailblazers/Envoy/GMT360.

The purchase of this kit includes a voucher for a FREE software fan patch – required to control the fans by computer. This kit includes the wiring harness, hardware, brackets, and a LS1 V8 dual fan assembly.

This kit will fit the 2006-2009 Chevrolet Trailblazer SS.
