The Ford F53 chassis with Godzilla V8 has improved power but still uses the same basic suspension design as previous models, which often requires aftermarket upgrades for optimal handling and ride quality in Class A motorhomes over 30 feet.
SDI E-Clik provides electronic shock control at about a third of Liquid Springs cost. Its not a complete suspension replacement but offers meaningful ride improvement for F53 chassis.
Bilstein 4600 is best value upgrade for E-450 Class C with occasional towing. Good balance of comfort and control. Koni FSD offers premium ride quality at higher cost. Both significantly better than stock shocks.
Keep boost switch wiring separate from DC-DC charger circuit. Add dedicated chassis battery charger or use DC-DC second output for trickle charging. Boost switch remains for emergency use.
