GMC Sierra 3500 HD Parts & Accessories

Shop GMC Sierra 3500 HD suspension, truck protection, engine-service and brake parts at Black Ops Auto Works. Compare FOX, Bilstein and ICON shocks, Fleece and Wehrli diesel components, Husky protection and other project options. Identify the generation, engine, cab, bed and single- or dual-rear-wheel configuration first.

Suspension Systems and Brake Service

Choose shocks by complete production coverage, axle position, supported ride height, adjustment arrangement, mounts and operating dimensions. Review ICON arms, torsion keys, tie rods, leaf packs and control or installation parts as a supported combination, including any SRW restrictions. For a Firestone air-spring package, check full chassis application and mounting requirements. Match PowerStop pads, kits and side-specific rotors to axle, side and installed brake dimensions.

Diesel Service and Exhaust Options

Compare Fleece, Wehrli and Exergy components by exact engine code, fuel and control version, coolant or turbo interfaces and installation space. Check the supplied pump, injector-set or service-part contents and required companion components. Choose exhaust parts by explicit GMC engine and body coverage, routing and connections. Confirm exact manufacturer application and intended-use restrictions for race-marked components.

Racks, Steps and Bed Protection

Plan BackRack frames, tonneau adapters and hardware together, and compare GEN-Y rack-only or panel packages by supplied contents. Choose Husky mats and liners using bed length, cab, retention and any stated MultiPro restrictions. Match hood or rocker protection, steps and Covercraft seat covers to exact body, cab or seat configuration. Check wheels, spacers and lug hardware by mounting specifications, load requirements and rear-wheel clearance. Select AMP replacement electronics for the supported existing PowerStep system.
