Hi James; what kind of trailer are you towing? There are suspension enhancement options that are compatible with your Fabtech lift on your 2021 Ram 1500.
If you want to use the Timbren SES # TDR1500DQ you were looking at it is possible with the addition of spacers. It is best to have a 1/2" - 1-1/2" gap between the Timbren SES and point of contact so you can add in the 1" spacer # A25723-90AH00 and 1/2" spacer # TA25722-90P00 to achieve this. The Timbren is a good option if you're towing or hauling most of the time. However, they can have a negative impact on unloaded ride quality.
If ride quality is a concern you can also use the Air Lift LoadLifter 5000 Air Helper Springs # AL57375. You will need the Air Lift Universal Air Spring Spacers for LoadLifter 5000 and 7500XL - 6" Lift # AL52460 as well. I prefer the air bags since they're adjustable and you can set them up to match whatever you're towing or hauling. You can also run them at the minimum 5 psi so they won't impact unloaded ride quality.

Hey James, how did things go with the suspension setup on your Ram 1500 and 6-inch Fabtech lift? Did the Timbren or the Air Lift system end up giving you the support you needed for towing and hauling? Your update could make it easier for others working with lifted trucks.
