GMC Sierra 3500 Parts & Accessories

The GMC Sierra 3500 delivers maximum payload capacity and exceptional towing strength, and the right aftermarket parts reinforce those attributes while adding performance headroom and distinctive styling. Parts support is strong across exhaust, suspension, and intake categories for owners of both diesel and gas variants.

Popular Upgrades

Suspension lift kits, exhaust systems, and cold air intakes are the most searched Sierra 3500 modifications. Towing accessories such as weight distribution hitch upgrades, gooseneck ball installations, and trailer brake controllers are also highly demanded by owners who regularly tow fifth-wheel trailers or heavy equipment.

What cold air intake works on the Sierra 3500 6.6L gas V8?

The Sierra 3500's 6.6L gas V8 accepts cold air intake kits from S&B and aFe that feature large-diameter intake tubes and high-flow dry or oiled filter media. These intakes improve airflow to the engine at high throttle positions and contribute to better throttle response and performance potential, particularly under heavy load conditions.

How high can you lift a Sierra 3500 for larger tires?

A 4 to 6-inch lift on the Sierra 3500 is achievable with quality kits that include extended radius arms and drop brackets to maintain factory driveshaft angles. At this height, owners can typically run 37-inch all-terrain tires on most wheel offsets without body trimming, which significantly improves both off-road capability and visual presence.
