The hitch will then push down on the rear of the truck. By using airbags instead of a WDH, in the same panic stop as above, the trailer weight will shift forward, pushing down on the hitch ball. When that happens, you can lose steering and braking capacity.Ī WDH resists the trailer’s nose-dive, and keeps the trailer’s tongue weight transferred forward. When you brake hard, the weight of the trailer shifts forward and pushes down on the hitch ball harder than normal, which causes the truck to lose front wheel traction. Without shifting some of the tongue weight to the front axle, you‘re likely to have problems in a fast stop or emergency maneuver. This is the key difference between a WDH and airbags. But the way a WDH raises the rear of the truck is key – it uses torsion to shift a percentage of the tongue weight to the front axle of the tow vehicle. Like an airbag, a WDH will raise back of the tow vehicle, reducing some of the sag caused by the trailer’s tongue weight. It provides more stability when encountering cross winds. It reduces sag caused by the trailer’s tongue weight 3. When installed properly, a weight distribution hitch has the following benefits:ġ. Airbags are great, but they are not a replacement for a weight-distribution hitch (WDH) like the e2.
