Recommended Rear Suspension Enhancement for 2019 Ford F-150 to Replace Stiff Bump Stops

Question:
I own a 2919 F150 3.5 ecoboost 4x4. I tow a 30’ TT that weighs 8,300 lbs loaded. My tongue weight is 1,040 lbs which is 12.5 of the weight of the TT. I installed the Equal-i-zer EQ37120ET 12K lbs and the Timbren Rear Suspension TFR1505E. The truck tows the TT well but when on poor roads, the bumpy ride gets pretty bad and it is tiresome. I am considering removing the spacer on the Timbren to see if that helps or replacing the Timbren system to a system that beefs up the rear suspension, but one that does not ride directly directly on the rear axle in hopes to ease the bumpy ride. I was looking at the SuperSprings Custom Suspension Stabilizer and Sway Control Kit Item # SSA28 or I was wondering about the air bag system but that too sits on the axle. With so many systems available on your web site, I am hoping you can make one or two recomendations. Thank you

Helpful Expert Reply:
Because the Timbren suspension systems like the # TFRTT1504E you installed operate more as a longer bump stop, driving in conditions like you've mentioned and with the spring not engaged to the axle while under load, you're going to get a bumpier ride. In order to address this, your best bet is going to be to remove the Timbren springs and install something a bit more forgiving.
The SuperSprings # SSA28 would work just fine, but I think there are better solutions for your truck that will provide better support on bumpy roads. If you wanted to go with something that's low maintenance then I recommend the SumoSprings Rebel Custom Helper Springs - 2 Piece - Rear Axle # SS95QR, which are a two piece helper spring that will provide you with a less bumpy ride than the Timbrens you're using.
The other option I recommend is the Air Lift LoadLifter 5000 Ultimate Air Springs w/ Internal Bumpers # AL88385, which require a bit more maintenance with keeping the bags inflated, but they'll also provide fully customizable support when towing. You can add or remove air from the bags as needed to provide less or more support and soften some of the bumpiness you're experiencing while towing.
If you want to go the air bag route and would like a way to keep the air bags inflated wherever you might be, I recommend adding an on-board compressor system like the Air Lift Load Controller Compressor System for Air Helper Springs- Heavy Duty - Dual Path # AL25856. This system comes with gauges and a control to inflate the bags from the comfort of your truck cab, so there's no need to find a gas station or even get out of the truck. This is also a dual path kit, so the bags can be inflated individually to compensate for off center loads.
