I noticed the link you gave was for really long TVP's, way longer than the XL.
If you are going to lengthen it might as well widen it too.
Here's a dicussion that has some info on that.

I might also be wary of that kit you posted, it does not come with a beefier engine plate, but comes with a skid plate.
Says "lifetime warranty" on bones but how long are they going to be around?
Just thought the link you posted might be questionable.
I myself would just go with some XL length tvp's and widen it.
