Thanks for the info. It might help explain why my truck doesn’t kick the rear out like some guys say sometimes happens when hitting bumps.

Curious. That combo (145" and HPP) don't appear in that chart. HPP only shows for 141", 157", and 164".

I'm trying to spec a 2019 with Max Tow and HDPP but it won't let me have anything other than the HD 18" wheels. LT tires are only showing in 18" size. What's the trick to get 20's? Maybe you can't anymore.
Also, I can't seem to get the 302a package with this combo. Is that right?

With the XLT did you order 301a? Anything above 301a gets the 156.8HD frame in that configuration due to payload restrictions. You do still get the rear spring upgrades and sway bar upgrades with the ordering of 20" wheels. This appears to apply to 2019 trucks. So far I have verified 5 xlt trucks and only the 301a trucks have the HPP frame. All the XL trucks have it when ordered with 156.8 frame and max tow from what I have seen in person. You can order max tow and max payload package together but its option restricted.
