Timbrem or Sumos on F150

Hello,

Does anyone have any experience with these two systems?

I installed the Timbren SES in a 2021 F150 4x4. Drove 600 miles and it was a jarring experience. I left a 1 inch gap.

Going over bridge joints or small potholes on the road wasn't pleasant. Truck was towing 7500lbs load trailer.

One benefit was less bouncing. Truck was leveled even though I expected rear to be 1-1 1/2 inch higher.

Would Sumos give a smoother ride?
Anything that can be done with the Timbren to soften the blows?

    I have the black Sumos on my F150 with a 1” gap. It rides like stock when unloaded and drops 2” when towing the 5th wheel. Would definitely buy again.

    Hi Dan, did you go with the blues (1000lbs) or black Sumos (1500)?

    We are towing 7500 lbs. It sounds like the blues are softer and may be easier over bumps.

    BTW, the gap doesn't create the slam effect when towing as the rubber is in full contact and compress. I think it is the hardness of the rubber in the Timbren that causes the jarring effect.

    I went with the blue ones since I have plenty of payload capacity but wanted to help with the small amount of rear sag.
