New lower air dam for 2017 Chevy Full size van
Been looking for an air dam that would work for the van since we bought it. Finally noticed the air dam on the 2015- 2019 Suburban. Picked one up and just installed it. Turned out pretty nice. Its about 3 inch too wide for the van bumper, but the ends can be easily and neatly be pulled in. If you want something about an inch higher the Yukon air dam my work for you. Looking for better mileage and safer highway driving. Now that the air dam is in place, I can start closing up the extraneous air leaks in the front end so only air will go through the radiator and intercooler. Then a front belly pan to help smooth the air flow under the engine.
Ahhh, Got the picture to work. The new dam reaches about 3 inches lower than the stock. I've been able to 33MPg @ A STEADY 68mph (trans just barely in 8 th gear) previously.... I wonder how much this may help.
