Review on Gabriel 49231 Hijacker: Your Ultimate Solution for Efficient Towing by Eric Williamson

I love these shock absorbers. I use them on my full size Chevy Van. It's not very busy most of the time, but when we're touring or using it for towing it's nice to be able to add some air and improve stability, especially on the freeway. The stock dampers can tolerate disconcerting sway when the van is loaded and moving at highway speeds. The installation is quite easy. I didn't even have to jack the car up. I routed an air duct to the filler neck. It goes straight to the tank filler hose. It's comfortable but protected and not intrusive.
