I'm for sure being too anal..I want perfection (because I love dialing in suspensions), but have to remember the Ram's a heavy, solid axle truck..there is no perfection (unless I throw ~7-8 grand into suspension upgrades at it)🤣
I also have ORG/ORP springs on Eibachs..set to 1.6" total front leveled lift (Clip#2).
The ride is fantastic on mostly smooth surfaces. When I hit cracks in the road, I can hear them but don't feel them..probably, that's due to the OEM Bridgestone Dueler tires.
In the rear, I have OEM...
Your 3.21 gear effectively becomes a 3.10 gear when going from a 275/55R20 to a 275/60R20 tire..that is barely any difference..I suspect you need to use AlfaOBD or Jscan, etc to reprogram the PCM/TCM for tire size/speedometer to get the trans recalibrated back closer to OEM characteristics again.
Thanks for that advice!
This morning, I was back to the 275/60s to keep it simple and same weight..now I'm leaning back to the 285/60s.
I know the 285s will have a more satisfying look! The tread is 16/32 compared to 12/32 on 275/60s or 11/32 on 275/55s..in theory, more rubber should mean more...
I will say that I did play up & down with cold psi quite a bit, and in the end found that the factory suggested 39psi cold (which runs up to ~41-42psi warm) is definitely the sweet spot for my setup..so maybe set your psi to a similar 20" wheel psi like mine and then fine tune it a bit if desired.
"Just saying"...very well said!
I do believe the Eibach coilovers & reservoir rears are digressive valved, like the Bilsteins, but seem to remember that the Pro-Truck struts and reverse-body rears are progressive valved..putting them in between Bilsteins and Fox 2.0s performance and comfort...
