For your 2021 Chevrolet Silverado 1500 Trail Boss, I recommend using the SumoSprings Solo Custom Helper Springs - Rear Axle item # SS45FR over the Timbrens. There are no compatibility issues with your Trail Boss edition Silverado. The SumoSprings have a 1,500 lbs capacity and will keep your truck level when you're towing or hauling a heavy load. They have progressive load control which means that the more weight you put on or in the back of your truck the more the springs will compress. This means that your factory suspension will not be affected when you are not hauling or towing. The Timbrens do not have this feature. If you install Timbrens on your truck it will give you a stiff uncomfortable ride when you are not towing.
