The AEV Rear Differential Skid Plate (commonly known as the Differential Slider) comes standard on the 2019+ Colorado ZR2 Bison and is now available to non-Bison owners as well! Instead of stopping you in your tracks, this Hot Stamped Boron Steel skid plate is designed to help you slide over obstacles. This type of situation might ruin your differential housing or pinion, rendering your car useless in the middle of nowhere.
The Rear Differential Skid Plate is standard on the ZR2 Bison, although it was built for the Dana M220 rear axle common in other 2015+ Chevy Colorado pickups, including the ZR2 and Z71 grade levels. Because of the Hot Stamped Boron Steel structure, this skid plate is not only extremely light but also extremely sturdy. The Colorado Rear Differential Skid Plate, including hardware, weighs just 9 pounds versus 20 pounds for our regular JK Differential Slider. It is proudly built in the United States and is E-coated for optimum corrosion protection.
Hot Stamped Boron Steel (HSBS) is a press hardened, ultra-high-strength steel that is most typically utilized in automotive applications for passenger impact protection due to its low weight and high yield strength (approximately 200,000 ksi vs. mild steel at 25,000 ksi). This material was chosen by AEV for the skid plate package on the Colorado ZR2 Bison not only because of its excellent strength-to-weight ratio but also because of its hardness and resistance to gouging.
- Fits 2015 and newer Colorado Z71 and ZR2 vehicles equipped with a Dana M220 rear axle.
- Protects the housing and pinion of the rear differential.
- Boron Steel, Hot Stamped — Extremely high strength-to-weight ratio
