DO you need a tunnel extension when extending rails to 136&q

[PZ9307]

I have a 2010 FX Nytro 121" I am going to extend it to 136". I have a factory trailer hitch on it, and want to still keep that. Do I have to extend the tunnel when going to a 136" or will the stock tunnel be adequate clearance for suspension travel?

Thanks

Yes, you'll need to lengthen the tunnel. I'd do a 128" skid relocate and rail extension combination to get to 136".

I wouldn't, I'd go with the 128" skid relocate to improve the tracks approach angle. The reduced angle makes a big difference in bump capability.
