Look into obtaining a RoadMaster Active Suspension (RAS)

 

If I used my truck "like a truck", my money would go for the Roadmaster Active as well. As it is, my truck is nothing but a full size car, so after leveling for looks and larger tires, 2.5", I also installed a 2" block, and have a 1" rake, measured it yesterday. Just enough to compensate for a load of groceries.
I've also installed an extra leaf in trucks, quite a few actually, even on a couple of my own. I always added the longest leaf available, directly under the main, with good results, a bit stiffer, but not bucking around at all, and improved the dog tracking you get on washboard. In fact, my Ranger rides better with a few mph's over washboard than it does at slower speeds. YMMV, just my world findings.

 

I added a 2” level to my 2020 FX4 and replaced the stock rear blocks with a 3” rough country ones.

Changes nothing of the ride quality except adding back the rake or somewhat close to factory rake. and you don’t sit nose high when you add weight to the back.

I’m running 285/65/20 (34.5” tall) tires and it looks and feels great.

Don’t forget to get your alignment checked if you install taller rear blocks, I started with just the level and had it aligned, adding the blocks changed the toe pretty significantly, so keep that in mind.

 

most likely it is 1.25"

You could swap the 1.25" block for a 2.0" block.

 

2” level front, 3” block rear. Driveway does slope but it sits great for me.

Stock 2020 FX4 rear block measurement.

 

Thanks for the replies guys.

I added the level only so I could clear bigger tires/more ground clearance. So the aesthetics of a level are not that important to me. If an AAL or taller block causes me to lose the “level look”, I won’t be upset.

This truck will likely never tow anything, so I think the RAS might be overkill.

Taller blocks and the autospring AAL appear to be similarly priced. Install of either part won’t be an issue.

I’m leaning towards the AAL just to help the leaf springs themselves deal with the load vs just lifting the rear and letting the leaf springs sag they way they currently do.

Again this truck is an every weekend off-road truck, and I’m looking to help improve the way it carries 4 passengers and the pup, two spare tires(assume this is non negotiable/ I know almost all of you have never had a flat etc, but this is non-negotiable), cases of water, coolers of food, shovels, wheel chocks, air pump, traction boards, and everything else that finds its way into the cab/bed.

Does anyone think blocks are the better route to go over an AAL?

 

For what you are using the truck for, that AAL would be my choice, after the RAS, the block won't help support anything. As long as you don't exceed what your truck has for a GVW, or payload. You might gain a bit of better handling as well in conjunction with good shocks, Fox 2.0 is my choice, followed by the Bilsteins.

 

Thank you for the input. I was out yesterday in Northern Arizona/Southern Utah hitting washboards at 45mph with the Bilstein 6112/5160 combo and it rode great. An earlier poster commented about how a few extra MPH really smoothes out the ride. I have to “two thumbs up” that as well.

 

Ha! I think that was me.

 

Ha! I was only on my first cup of coffee at that point lol.
