Does 2-1/2 Inch Rake on Rear Suspension of Ford F-150 Affect Weight Distribution Set Up Procedure

Question:

My F-150 has a built-in rake with the rear about 2-1/2 inches higher than the front, and weight is 55 front / 45 rear unloaded. I dont know what is the goal for the VEHICLE not the trailer when I trailer: 1. Do I want the rake to stay at 2-1/2 or is it OK/better if the truck goes to dead level? 2. Do I want the weight distribution on the two truck axles to stay at 55/45 or would a 50/50 weight distribution be ok/better? I already know not to exceed any axle weights or gross weights.

When setting up the system for the first time, it's the front wheel well height that you'll be concerned with, so the rear rake doesn't really make much difference.

What you're looking for is the trailer tongue weight to have the smallest increase on the front wheel well height to the ground as possible. If the rear end squat from the weight distribution system causes the front suspension of the vehicle to unload or rise, you'll have all kinds of issues like incorrectly aimed headlights, and reduced steering and braking performance, none of which is good. How the front wheel well height changes from when the trailer is uncoupled, to coupled to coupled with the weight distribution bars engaged is what you want to pay attention to. The rear wheel well or suspension height isn't that important.

You don't mention which system you're using, but your best bet is to check out the installation/set up instruction for specific advice. If you'd care to reply with which system you have, or which you are considering, I'd be happy to provide more specifics.

I've linked to a weight distribution install/setup help article that you may find helpful.
