Just bought a 2021 Custom Trail Boss Crew Cab 4x4. After a few trim add-ons (bed liner, custom seat covers, etc.), I’ve been quite happy with the truck, with one exception. I work in an area of West Texas and SE New Mexico on lease roads made of kaliche rock, akin to concrete. As the surface wears, it becomes the equivalent of driving over an aged parking lot with deep holes, large chunks of hard cement and very hard ripple/washboards. The front end suspension is serviceable, but with the light bed and stiff rear Ranchos, the back of the truck is taking a literal beating. Enough so that the rear doors are getting slack and starting to ‘clank’ after only 4,000 miles on the truck. Is there an after-market mod, such as air kits, that will smooth out the ride? GM says there are no mods for this edition as this edition was the mod. I’m not expecting Baja level performance and understand good shocks need to be stiff to keep the tires planted... but anything that will keep the truck suspension from sounding like it’s 15 years old at the 12 month mark is a must. There will be little other than misc small supplies kept in the bed so load weight is not an issue. We run trucks solely for ground clearance concerns due to the depth of the potholes. Any help appreciated.
