The best way to give your 2013 Forest River Wildcat extralite 312BHX a lift of about 2 inches will be with the tandem axle lift kit part # RR23QX which will raise the suspension 2 inches. Using the other shackle bolts you mentioned might make a slight height difference but not 2 inches. view full answer...
With the tire size you mentioned, you could have either a 6 on 5-1/2 bolt pattern or 8 on 6-1/2. I was not able to determine which option is correct given your RV information. But, I have included a tire/wheel option for both patterns in both an aluminum option and steel option. All of the options are a 16" wheel and work with a ST235/80R16 tire.

If the landing gear of your 2013 Forest River Wildcat Extralite 272 RLX is a Lippert, Venture, or Stromberg Carlson the correct replacement motor is the part # LC141893 that you referenced. This is by far the most popular setup out there so it would seem very likely this is what you have and what you would need. But if you have something different let me know and I'll see what we can get for you. view full answer...
