We offer 4 different electric fan kits for the Trailblazer SS. Whats the difference between them? Which one is right for you?

Below is some information on each kit to help you make an informed decision about what fan kit is right for you.

These are in order from lowest to highest cost.

All of our fan wiring kits utilize heavy duty relays for trouble free installation. The wire harnesses are made by PCM of NC.

LS1 Fan Kit- $450 – https://stcharlesgarage.com/product/trailblazer-ss-dual-electric-fan-kit-three-relay/

This is our basic entry level kit. It retrofits electric F-body Camaro fans to the truck using included bracketry.

This kit works well and can be found on many trucks across the country. I ran this kit on my personal truck for years around Chicagoland without any issues.

If you live in a part of the country where you will be driving in 100F+ in traffic or if you are running a turbo or supercharger setup I would suggest getting one of our other kits.

This kit flows 2400 CFM.

Derale Fan Kit – $685 – https://stcharlesgarage.com/product/derale-dual-12-electric-fans-for-trailblazer-ss/

This kit uses a universal Derale fan kit that fits pretty well on the Trailblazer SS radiator. This is not a direct fit, you will have to make some custom bracketry to install it.

This kit flows 4000 CFM.

SCG Brushless Fan Kit – $785 – https://stcharlesgarage.com/product/trailblazer-ss-dual-electric-brushless-fan-kit/

This kit is exclusive to us. It utilizes 2 12″ brushless fans that flow ALOT of air. This kit will work great on trucks that are heavily modified and need more airflow to keep them cool.

This kit uses a shroud specific for the Trailblazer SS so it installs easily and cleanly. No drilling or cutting required.

I am currently running this on my personal truck and it has been working really well.

The only “downside” to this kit is the fans are pretty loud. Kind of sounds like a baby tornado under your hood. But that’s just part of moving alot of air.

This kit flows 4200 CFM.

SPAL Fan Kit – $795 – https://stcharlesgarage.com/product/spal-dual-12-hd-electric-fans-for-trailblazer-ss/

This kit is a tried and true kit that has been around a while and moves alot of air. The fans are heavy duty SPAL 12″.

This kit uses a shroud specific for the Trailblazer SS so it installs easily and cleanly. No drilling or cutting required.

This it flows 3740 CFM.
