Using this Duramax Dual Shock Hoop Kit is simple. First, make sure your truck is one of the compatible models (2001 - 2010 GM Heavy Duty 8 - Lug 2500HD/3500 Trucks and Hummer H2, not Suburban or 1500HD Trucks). Then, follow the installation guide by clicking the provided link. When using your truck, these shock hoops will help you run 2 performance shock absorbers on each side, improving the ride quality. As for maintenance, there's not much you need to do. The hoops are powder - coated for durability. But it's a good idea to check them regularly for any signs of damage, like scratches or loose welds. And remember, this kit comes with a lifetime warranty, so if you break it for any reason during normal use, Kryptonite will replace it.
