Description

Finally an aftermarket upgrade option for Trailblazers! This TBSS Spal kit includes two high flow HD 12 inch Spal fans and a custom black powder coated shroud that uses factory mounting points – no drilling or cutting needed! Fits 5.3L and 6.0 Trailblazers/Envoy/GMT360. This conversion eliminates the power robbing stock electro-viscous fan and replaces it with two computer controlled electric fans. Each fan is independently controlled by the PCM.

These HD fans are suited to highly modified set ups (stroker, forced induction, or a hot climate).

The purchase of this kit includes a voucher for a FREE software fan patch – required to control the fans by computer. This conversion has been credited with gains ranging from 12-18 RWHP and fuel economy improvements of around 1 MPG.
