Hey all, my 22 is a nice truck. First and only raptor I’ve driven. I’ve owned a ton of other trucks (Tacoma-1 ton duallys). One thing I’m noticing is that the suspension isn’t quite what I’d expected. It’s a bit stiff in sport and in normal mode and sometimes hitting normal highway bumps seems to unsettle the truck. It’s not as far apart from the other trucks as I would think it should be.
Any feedback is appreciated. This sound right to others or should I be getting the suspension checked out?

you likely need to do a ride height recalibration on completely level ground. if you dont have forscan, you can putting the truck into engineering and test mode first (its a part of the ride height recal process and when my suspension starts acting up (i think i have a solenoid thats going bad) i can do this quickly and it resolves the harsh ride).

to put it in E&T mode, find level ground, put the truck in neutral while it is on then hit the M (manual shifting) button so the truck enters the mode so that it can be towed. shut the truck off while it is in neutral. Next, with your foot off the brake so the engine doesnt start, hit the start button then floor the gas pedal (ie push all the way in then release fully) 3 times in a row. once you've done this you will see an "ET" symbol pop up in the bottom right corner of the dash. give it a few seconds then shut the truck off. start and drive away as usual--hopefully this will help.

If the ride is still stiff or acts strange over bumps, do the same thing as above, but while you're in ET mode, plug forscan in and run the ride height recalibration (there are threads with screenshots on exactly how to do this with forscan on this site). hope this helps!

I have a '23 truck on 35s, would this help me - or why would I need to run a height recal on a stock setup?

I posted something similar in this link

Now running 37/33 cold that seems to help but realized by this 2nd link that I'm not really solving the issue more that I'm covering it up

You'd want to do it if:
- you have an abnormal rough ride
- your suspension is acting strangely over bumps/changes in the road (ie seems bouncy or is pitching back and forth strangely)
- you've added new springs, control arms, shocks, etc.
- your truck has thrown the drive modes/exhaust modes/steering/shock etc are no longer available message and your suspension has gone full stiff

If you've done or experienced any of these things, there's a good chance that ride height data that your shocks are sending back to the vdm is out of whack meaning the electical current the vdm (or whatever module) sends to the shocks changes stiffness to account for changes in terrain, etc. will be wrong and will feel it. I've had some of the issues outlined above and it is very noticable...and so is the improvement in ride quality/suspension performance post recalibration.

You can check to see if your ride heigh measurements are out of whack this by parking your truck on a flat space and using forscan to measure the ride height at all four corners (see this thread)

in the summer ive been running 32/30 cold that heats up to 36/34 hot. ive noticed anything above that pressure wise is significantly more stiff. Winter i do 34/32 cold.

Sometimes reading threads about this, makes me wonder how I would know that anything is wrong if I never knew what was the proper in the first place.

Guess now I need to find some nevel ground and check it out at rest. Now just to find level ground in the mountains
