Hey fellas have a simple question that just slipped my mind. Yesterday I loaded my 97 f350 4x4 auto reg cabs bed up with concreat and brick and noticed the front upper bump stop on the rear leaf springs were touching the leafs. Honestly was surprised since I didn’t think I had that much product in the bed. Is that a sign I’m maxed out payload wise? Couldn’t remember but thought that’s how you could tell? Cause I have a at least half a bed load left. Thanks in advance. Kyle
If you are referring to the L shaped brackets that mount to the frame by the front and rear of the springs, they are toe overload brackets. Not really overload, but they come into play to help the lower spring pack when a load is applied. When no load is in the bed, the upper spring does not touch allowing for a little softer ride.
If your looking to see how close to "loaded" you are you should be looking at the rubber bump stops that go from the frame to the axle. You'll have to kneel down behind the truck to see it rather than look through the wheel well in most cases. My truck gets run on the overload springs on a regular basis when towing gooseneck trailers
For short local trips I usually let the tires tell me when the truck is fully loaded. For long trips, riding on the overlord is fine but I try to give the bump stops (the ones on the inside that Blue mentioned) plenty of room to move without bottoming out.
