Product Description

Finally an aftermarket upgrade option for Trailblazers! This kit includes two high flow 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.

Spal Fans & Shroud ONLY – Available if you already have one of our electric fan harnesses (made after 2011) and only want to upgrade the fans.

Three Relay Spal Kit – Complete kit with harness that will bring both fans on at half speed for the LOW setting for quieter operation, and both fans on at full blast for HIGH.

Upgrade to HD Fans – Available as of October 2019! While our basic 12″ Spal fan upgrade is a hit, we have an even more heavy duty version of this kit now available with a thicker, stronger 12″ fan. This option is better 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. These fans can be hard on the electrical system, our three wire battery cable upgrade kit (P-070009 & P-070010) is highly recommended.

Now available for rental or purchase – PCM of NC Fan Clutch Wrenches! Simply add to your cart at checkout and save yourself a trip to the auto parts store. Don’t want to keep it? Send it back within 30 days in working condition for a full refund!

Our manual fan switch (link) is also available for purchase with this kit. NOTE: Fan codes P0480, p0481, and p0483 need to be disabled in your tune for the fan switch, and set to NO ERROR REPORTING. We will do this for free if you send in your ECM.

    Fantastic kit! Installs quick and easy. It really helps keep the temps under control. My TBSS has never ran so cool. Kit looks factory except the high tech look of the SPALS themselves. Harness is plug n play except for installing pin out on PCM plug. It’s not difficult at all just take your time and follow directions plus you can always count on PCM OF NC to be there for you after the sale if you have questionst or need support!

    Very nice kit. After discussing with you guys everything was ordered and arrived on time. It went in fairly straight forward with a few tools. Fans operate very smooth and would recommend the upgrade with the re-Tune and tranny tune. Truck spins up in revs quicker and better response.

    Great products, 100% satisfied with combination of fan kit, 160′ thermastat and mailorder tune. Went together in about a weekend, one day turn around for PCM and TCM is as good as it gets. Thanks Mark for the great help and info.
