Description
An updated and upgraded version of our two relay electric fan kit – 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. Fans sold separately – HERE. This harness is only meant to support LS1 Fans, or the PCM of NC Spal Fan Kit.
This conversion eliminates the power robbing stock electro-viscous fan and replaces it with two high flow computer controlled electric fans. This conversion has been credited with gains ranging from 12-18 RWHP and fuel economy improvements of around 1 MPG. 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 and brackets to install LS1 V8 (98-02 Camaro/Firebird V8) Fan assembly sold separately, for LS1 fan assembly click HERE. Also available as part of our SPAL fan kit, which includes two powerful, high quality SPAL fans and a custom made aluminum shroud. Designed as a direct fit for the Trailblazer and powdercoated black for the cleanest possible install. Click HERE for more info.
