Better shocks

I think that Ford uses better shocks as OEM. The shocks on our F350 are actually quite good ( factory ).
The OE shocks that came on my Nissan....all I can say is Nissan must have told the supplier, "give us shocks and we're gonna pay you about $1 each for them..." They were lame from the get-go. So I swapped them out immediately.

Bilstien 5100's and sway bar. Your done!

I've got the Rancho 9000XL's on my truck, and am quite happy with them. I chose them over the Bilstein's because the tube and the rod are much larger diameter. And, the Rancho's cost quite a bit less on sale and after rebate.
The Rancho's are also a grayish color, rather than the yellow of Bilstein's.
Monroe's are Rancho's street shocks. I would not recommend them for a truck or for towing.

I went to Bil 5100's on my Frontier and also added a Helwig rear anti-roll bar. Huge improvement in both day to day driving and towing handling.

Better shocks, of course. Now that 40 PSI in the tires may be an issue. You should have LT tires with a much higher pressure.

I switched over to Bilsteins and what an improvement. For years I read about people claiming that their ride has transformed since they slapped on Bilsteins, but I was never convinced. Always thought they were just another over priced shock and people were attempting to justifying their purchase lol. I purchased a set and the truck rode better than it did when the OEM shocks were new. Now, if Bilstein makes a set for one of my vehicles then they're going on.

I'm not sure what year your truck is, but if it's a 09'-13' then Bilstein makes shocks for your truck. Since you have a 4x4 the 5100's may be a better choice since the shock has a little bit extra length over the 4600 series shocks. I don't believe they make a shock yet for the 14'-current trucks.

Monroe Reflex series have done well for me. Not as harsh as some HD shocks when empty and good damping when loaded.

I have used Rancho and Bilstein with good results.

I went from Rancho 9000 adjustable to Bilstein's . I think they are # 4600's with blue covers.

Both were a great improvement over OEM's . I found that the adjusters on the Rancho's became corroded over time due to heavy road salt ( but that took a few years and 50k miles ). However , the quick n easy twist of the dial on each shock made the ride fine tunable, unloaded truck vs loaded truck. Setting range from 1 to 9 ( 9 being the stiffer ride )

Both shocks work very well and made the ride loaded or unloaded, a real 'smoothie' .

correction...I do have the 5100's . not 4600's .
