The Silverado Trail Boss takes Chevrolet’s brand’s iconic pickup to a new level of off-road capability, adding equipment like a two-inch suspension lift, Rancho monotube shock absorbers, a high-capacity air filter, skid plates, Hill Descent Control, and an automatic rear locking differential. However, buyers aren’t limited to just a single Trail Boss trim level. In fact, there are two variants on offer – including the Trail Boss Custom and the Trail Boss LT. We have stacked the two trim levels side-by-side in this GM Authority comparison.
Let’s start with the mechanical specs. The standard engine in the Silverado Trail Boss Custom is the naturally-aspirated 4.3L V6 LV3, which produces 285 horsepower and 305 pound-feet of torque, mated to GM’s 6-speed automatic transmission. Meanwhile, the standard motor in the Trail Boss LT is the naturally-aspirated 5.3L V8 L84, which produces a more potent 355 horsepower and 383 pound-feet of torque, mated to GM’s new 10-speed auto. From the onset, the starting price of these two models is roughly $7,000 apart, before adding any options.
Buyers looking at the Silverado Trail Boss Custom, however, can spec theirs with a more potent engine via the optional, naturally-aspirated 5.3L V8 L82. The L82 makes the same 355 horsepower and 383 pound-feet of torque as the L84 in the Trail Boss LT, but it has the less advanced Active Fuel Management system as opposed to the L84’s Dynamic Fuel Management feature. Another key difference is that the L82 in the Trail Boss Custom continues to be mated to the 6-speed auto. Meanwhile, the optional powertrain option for the Trail Boss LT is the atmospheric 6.2L V8 L87. The L87 is the most powerful engine on offer for the Chevrolet Silverado 1500, and it offers 420 horsepower and 460 pound-feet of torque, while being mated to the 10-speed auto box. The difference in the starting prices of these two models is about $8,000.
Finally, the Trail Boss Custom can also be optioned with the L87 V8 with the 10-speed automatic transmission. That combination raises the starting MSRP to $46,365.
Axle selection is another point of departure for the two Silverado Trail Boss models: the Trail Boss Custom pairs the standard V6 engine with a 3.42 unit. The Custom’s two optional engines pair to a 3.82 axle as standard, or a 3.72 axle with the Max Trailering Package.
The Silverado Trail Boss LT, meanwhile, is equipped with a 3.23 axle as standard, or a 3.42 axle when equipped with the Max Trailering Package.
On the outside, the Silverado Custom Trail Boss mounts black sideview mirrors and halogen headlights as standard. The Custom’s standard exhaust setup is a single side-exit pipe with a polished tip (with the standard V6), while the optional V8 engines add a dual integrated exhaust.
By contrast, the Silverado Trail Boss LT gets glossy black sideview mirrors and LED headlamps, or high-intensity LED headlamps when equipped with the Midnight Edition package. The LT also gets a dual integrated exhaust across the range. It also offers wheelhouse liners (with the optional Bed Protection Package). The feature is not offered on the Trail Boss Custom.
Both Chevrolet Silverado Trail Boss models get the 18″ x 8.5″ high gloss black painted aluminum wheels as standard, and both offer the 20″ x 9″ painted aluminum wheels with a machined face and gray accent pockets as an option. However, only the LT can be optioned with another set of 20″ x “9” black painted aluminum wheels from the factory (those these can be purchased after the fact).
The final area where the two Silverado Trail Boss model variants differ is in the cabin, with the Custom offering a 40/20/40 split-bench configuration, and the LT offering either a front 40/20/40 bench with covered armrest storage and under-seat storage, or front bucket seats with a center console.
The seating materials are also different, with the Custom covered in cloth, and LT covered in cloth as standard or with leather as an option.

Ultimately, the Trail Boss Custom is set apart by a less powerful standard engine, halogen lighting, and cloth seating. By comparison, the Silverado Trail Boss LT is a more premium truck – with a more powerful standard engine (plus a 10-speed automatic transmission), LED headlights, and available front bucket seats as well as leather.
