Always confirm your exact cab style, bed length, and drivetrain configuration prior to ordering to ensure a precise fit on your specific build. This kit is not designed for 1500 half-ton or non-HD variants. • Eliminates rear-end sag and body roll under maximum payload, keeping your truck level and stable even when fully loaded to 5,000 lbs • Adjustable pressure from 5 PSI to 100 PSI lets you fine-tune ride height and spring stiffness on the fly — firm for maximum loads, softer when running empty • Dramatically improves towing stability when pulling fifth-wheel, gooseneck, or heavy bumper-pull trailers by reducing rear squat and steering wander • Works with both 4WD and RWD Silverado and Sierra 2500HD and 3500HD builds without any modifications to your factory drivetrain or frame • Bolt-on installation design eliminates the need for cutting, drilling, or welding, preserving factory frame integrity and keeping your warranty concerns minimal • Ideal for commercial fleet operators, contractors, ranchers, and anyone who regularly pushes their HD truck to its rated payload or tow capacity • Load Capacity: 5,000 lbs per complete kit • Pressure Range: 5 PSI minimum to 100 PSI maximum adjustable • Vehicle Fitment: 2001-2010 Chevrolet Silverado 2500HD, 2001-2010 Chevrolet Silverado 3500HD, 2001-2010 GMC Sierra 2500HD, 2001-2010 GMC Sierra 3500HD • Drivetrain Compatibility: 4WD and RWD configurations • Mounting Location: Rear axle, behind the leaf spring assembly • Installation Type: Bolt-on, no cutting or welding required • Inflation Valve: Standard Schrader valve compatible with any air compressor or air tank • Included Hardware: All mounting brackets, air lines, fittings, and fasteners included for complete installation These air springs are built from reinforced rubber composite with heavy-duty internal baffling designed to handle the sustained heat, flex, and pressure cycles that come with real-world commercial and work-truck use. The outer air bag sleeve uses multi-ply reinforced rubber rated for consistent performance across a wide temperature range, meaning it will not crack, delaminate, or lose pressure integrity during cold Minnesota winters or scorching Texas summers. The mounting brackets are constructed from heavy-gauge steel with a corrosion-resistant finish to stand up to road salt, mud, and the abuse of off-pavement job sites. Every component in this kit is selected for durability under the demanding load cycles of HD truck ownership, not just occasional light use. This is a product built for contractors, fleet managers, farmers, and anyone who treats their Silverado or Sierra as a true working machine day after day. Installing this air bag suspension kit is a straightforward job for any DIYer with basic hand tools and a floor jack. Begin by safely lifting the rear of your 2001-2010 Silverado or Sierra and securing it on jack stands. Remove the rear wheels to gain clear access to the rear suspension and leaf spring area. Locate the factory mounting points behind the rear axle — no drilling or frame modification is required. Attach the provided steel mounting brackets to the existing bolt locations using the included hardware. Slide each air spring bag into position between the bracket and the axle pad, then torque all fasteners to spec per the included instruction sheet. Route the included air lines from each air spring forward along the frame to your desired inflation point — a cab-accessible valve stem, an onboard compressor, or a manual Schrader valve accessible from the wheel well. Pressurize each bag to your desired starting PSI (5 PSI minimum when empty, up to 100 PSI at maximum load). Reinstall wheels, lower the truck, and verify even ride height side to side. Total install time typically runs two to three hours for a capable home mechanic. Always re-check torque and air pressure after the first 50 miles of driving. • 2 x Rear air spring suspension bags (left and right) • 2 x Heavy-gauge steel mounting brackets • Air line tubing and fittings • Schrader inflation valves • All mounting hardware, bolts, and fasteners • Full installation instruction sheet At Expedite, we stock parts built for real working trucks, not just show rigs.
