Looks like the restriction only applies to XL/XLT spec'd with that as an option, the matrix above doesnt list restrictions on the models that come with it standard.
Bigger concern (for me) is the high-capacity axle restrictions... may be the push I needed to bump my order down to an FX4 and then save up for Carli suspension down the road (does that mean I get kicked off the forum?

). I really wanted some of the misc extras that come with the Tremor like the Torsen front dif and extended breather tubes.
