Description

This TBSS brushless fan kit includes two high flow brushless Proform 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.

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

No fancy special controller required, just wire up the (+) and (-), and you’re ready to go. Soft start ramp up prevents amp spikes. This is strictly a puller fan and is not reversible.

This kit can be purchased as DIY with no wiring or relays or for a simpler installation we can include a 2 relay wiring kit that is controlled by the factory ECU.

When purchased with the relay kit the kit includes a voucher for a FREE software fan patch – required to control the fans by computer.
