Question:

I have the lowers installed on the back of the springs. Can I use them on the back of the leaf springs and not the front? If not what would you recommend. I already have upper stable loads and Timbrens. I’m hauling a 5000 pound truck camper and it still squats more than I want. Thought about adding more springs but I don’t want to remove the overload springs. I also thought about replacing the Timbrens with 7500# airbags. What would you recommend

Expert Reply:

In regards to the Timbren Suspension Enhancement System, you should be using part # TFRTT350J which is designed for models with an in-bed camper, not part # TFR350SDJ which is designed for standard trailer towing. If you're using the wrong set then that would explain the extra sag. If you do have the correct set or even if you don't, the best option for loading leveling would be a set of air bags as they allow you to adjust the pressure for the best mix between support and comfort. I recommend the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs part # F95FV. These will be a bit better than the Air Lift option as they have a higher psi rating so you can put more air into the system if further leveling is needed.

In regards to the TorkLift StableLoad Rear Suspension Upgrade, I cannot recommend installing any other way than what is described in the instructions.
