What is a TBSS Spal Fan Kit?

Information on TBSS Spal Fan Kit

A very popular modification for the Trailblazer SS is our Spal Fan Kit (link). Removing the factory fan subtracts a lot of weight off the front of the motor – adding about 15rwhp and usually picks up a mile to the gallon as well. This kit also frees up a lot of space in the engine bay, for a cleaner looking build. This fan kit is controlled by the ECM (with changes made with HP tuners). It will come on with either engine coolant temp, or with air conditioning as well. This kit is easier to install than our LS1 fan kit, as the shroud drops in and doesn’t require any trimming.

What is included with the Fan Kit?

Our Spal fan kit includes an aluminum fan shroud, which we make in house. The shroud has cutouts with rubber flaps for ventilation, and is powder coated black for a nice finish. The kit also includes the three relay harness and the appropriate hardware to mount it to the shroud. The kit will also require the ECM (engine control module) to have the fan settings patched. We host these settings online, or if you do not have access to HP tuners, you can email in your ECM and we will patch it for free (you just need to cover shipping). Please note: our fan kits are only meant to be used with the Spal fans that we supply. If you want to use them with another aftermarket fan, please reach out and verify your application first!
