Will lowering my truck with the Hotchkis Leaf spring affect the towing capacity?
Anytime you lower a truck regardless of what you use (springs, shackles ect.) you will loose towing capacity. The reason being is that you loose travel. What happens is that when you lower the vehicle 4 inches, you become closer to the bump stops. Then when you load up the bed with a load, now you are on the bump stops. No more travel. Not good for the truck. The fix to this situation would be to use an air bag assist to help with towing.
