Hi I salvaged this from my rv motor home that the step was storm damaged and had to be completely replaced but this part was unaffected I salvaged it to simply help with my insurance deductible the motor home was only 1 1/2 years old at the time of salvage my understanding is it’s compatible with all kwikee Lippert steps except the actuator arm and the power input plug port for the motor please take notice of these in photos the arm actuator is actually removable if you’re arm isn’t damaged it can be replaced with yours as my understanding shipping is USPS ground advantage
