2020 Ranger Bouncy Ride

[Mark12]

As I attempted to lessen the bouncy ride by trying different (tire) air pressure (increased the pressure to 38psi and then stayed with 35psi) and it helped to some degree. I recently replaced the Hankook original tires with Cooper 265/60R18 DC AT3 4S tires. What a difference. The ride is much improved and my truck feels like a truck not a circus ride. I'm back to being happy with my Ranger.

The Hankooks were "bouncy"?

A good 10ply or E rated tire helps tremendously. My truck came with Bridgestone Dualers. I changed them out at like 1000 miles or so. But once I put the 255/75r17 10plys on I lost a little fuel mileage but the ride was way more firm and responsive.

I replaced the rear shocks already. Had a vibration I couldn’t pin down and it was worse on some roads than others. Got plain old Monroe Gas from Rock Auto, problem solved.

i wonder if they were just under valved?

I don't know about the other shocks but the ones that come on the FX4 are valved to give you that old school luxery car ride. You get the truck spring ride but the LTD bob. I'm sure that will work out well on the trail.

if you want to follow the terrain don't the wheels need to drop into holes fast?
for cornering on smooth roads, yeah, stiffen 'em up.

many years ago I was in a restaurant and across the street was a big hole. I watched the wheels on bunch of vehicles
bounce in and out of that hole. you would be amazed at how far wheels move when they are forced out of a hole at 40 mph.

For regular off roading, you want a solid if not stiff suspension. You want as little bounce as possible or a rock may put a hole in something you don't want a hole in.

For a Baja, beech driving, and other off roading may have different desirable ride characteristics.

There is a balance. I think softer side is generally better but the shocks have to be matched with the springs.

From what I gather ford kinda biffed that at least with the fx4.

My take on the late-model FX4 shocks, and it's just a theory based on what I read, is that the compression is a little soft to absorb bumps off-road but the rebound is up there to plant the tires back on the ground after hitting the bump. Most shocks are 50/50, meaning compression and rebound are equal, but it wouldn't surprise me if the FX4 units were like 40/60, which may not be ideal for on-road.

They do suck on road. I have to get some real off road tires on the thing before I can say whether that opinion stays the same off road.
