The Ultimate Fix: OWL Vans Arrow Suspension (Trail 2500)
The OWL Vans Arrow suspension kit, featuring custom-tuned Falcon shocks, is the gold standard for heavy Sprinters. These massive 2.25-inch and 3.3-inch shock bodies hold significantly more oil than factory units. More oil means better heat dissipation, entirely preventing the "shock fade" that plagues vans driving down long, steep mountain grades into the desert.
What truly sets this system apart is its rapid adjustability. The rear shocks feature a prominent tool-free dial. You can leave it on a soft setting to comfortably absorb potholes on the 5 Freeway, and simply click it over to a firm setting to prevent bottoming out when you hit rocky BLM land.
