I recommend the Firestone Ride-Rite Air Helper Springs, # F2609 for your 2021 Chevrolet Silverado 1500. This option fits ether the 2 wheel drive or the 4 wheel drive models. The 5,000-lb capacity of the Ride-Rite air springs enhance your factory suspension for safety and stability, reduce strain on your rear axle and keep the truck level. You can adjust to load size for a consistently smooth ride.

The most common leaf spring size for a 6k trailer axle is 25-1/4 inches like what the part # e34SR is. It would be smart to measure what your old one is first though. We have a shorter spring with the part # e47SR which is 25-1/8 inches. view full answer...
