Question:

Hi, Im trying to decide between the Timbren FR350SDJ and the severe service FRTT350J. Its for a 2019 F350 DRW 4WD that hauls a 5000 lb slide-in truck camper. I already have StableLoads both upper and lower, so theres no sag. What Im trying to do is replace the airbags I have now typically run at minimal pressure with something I dont have to worry about leaking somewhere inconvenient. Adding some additional side to side stability would be a secondary goal. The issue is this: with the StableLoads, do I need the severe service Timbrens or just the regular ones to accomplish this goal? Im trying to NOT introduce a rough ride with the camper off and the Lower StableLoads removed, while improving stability with the camper on and the StableLoads in place.

Expert Reply:

If you plan to have the truck bed camper removed more often than not, then I would instead go with the standard
Timbren Suspension Enhancement System - Rear Axle # TFR350SDJ. This would not cause a harsh ride when the truck is unloaded, but it would still provide plenty of suspension enhancement and side to side stability. I think this option would be a safer route; also these Timbrens work well with the TorkLift StableLoad Rear Suspension Upgrade # TLA7311 you have installed.

If you plan to have the truck bed camper installed on your 2019 Ford F-350 Dually more often than not, then I would go with Timbren Suspension Enhancement System - Severe Service - Rear Axle # TFRTT350J as it would hold up better to the constant stress on the rear suspension. The downside to using this with an empty truck bed is that it would cause a harsh / rough ride in the cab. I attached a demonstration video for you to check out.
