Question:

The TFR350SDJ light duty is not available. These HD versions are.We tow a 35foot LQ Gooseneck Horse trailer cross country.The tongue weight is much higher than our last 26foot and instantly s our SW F350 4x4. Will these be too much?

The Timbren Suspension Enhancement System - Rear Axle # TFRTT350J you were looking at will fit your 2021 Ford F-350 4WD but are very stiff and will lead to a very harsh unloaded ride.

Instead I recommend the SumoSprings Rebel Custom Helper Springs - 2 Piece - Rear Axle # SSR-128-47-2 which offers 4600lbs of load leveling support which will be perfect for providing support to the rear suspension of your F-350 when towing your 35' LQ Gooseneck Horse Trailer.

These springs are progressive rate meaning the first bit of the spring is soft so your unloaded ride quality is not affected, but then stiffens up the more it is compressed.

I included a video of the # SSR-128-47-2 for you to take a look at.
