This is why we do what we do.

Chance Digiulio gets it. Loving what you do makes all the difference.
Getting to travel to events, shake hands, meet customers and see the people behind the support is a huge part of why we do what we do. At the end of the day, Jake de la Pena and the DMAX Team get to wake up excited to come to work. That’s pretty hard to beat.

A clean install with a factory-style finish.
The Pod Holes Rear Light Kit puts a pair of Baja Designs S1 lights right inside the factory bumper steps on 2015–2019 Silverado and Sierra HD trucks.
No cutting or splicing into the factory wiring. Just plug in the harness and get brighter backup lighting automatically when you hit reverse, plus auxiliary control when you need extra light.
Here’s a quick look at the install.

🔧Tech Tip Tuesday
Stop over-greasing your ball joints.A little grease goes a long way.
Properly greasing your ball joints helps reduce wear, keeps contaminants out, and extends the life of your steering and suspension components.
Grease them until you see the boot just start to swell. Don’t keep pumping until it looks like it’s about to burst.
Stay on top of your maintenance and keep your Duramax on the road.
