What’s overlooked most often is quality shock absorbers. Entry level Koni or Bilstein far better than OEM or usual aftermarket, and King or Fox is a substantial upgrade for handling, braking and steering, not just ride.
Polyurethane bushings to replace the rubber anti-roll bar bushings is another. The truck handles just that wee bit better. Better predictability with both. Measure and order Energy Suspension greaseable type. Cheap and etfective.
Don’t say, well, Truck is new, etc. Towing exerts stresses where these will shine. I do it off the dealers lot.
