2026 Chevrolet Silverado 1500 Custom: Marion Buyers Guide

2026 Chevrolet Silverado 1500 at Jim Cook Chevrolet in Marion, NC

Quick Answer: 2026 Silverado 1500 Custom

Custom, from $42,400 MSRP, adds style and convenience content over WT and is the first trim where the Duramax 3.0L turbo-diesel (305 hp, 495 lb-ft) becomes available as an option alongside the standard 2.7L TurboMax turbo-four. It's also the trim Chevrolet builds Custom Trail Boss from, for buyers who want the off-road package without stepping up to LT-based content. Custom keeps the 8-inch touchscreen; the larger 13.4-inch unit is reserved for LT and above.

The diesel door opens here

Custom is the practical starting point for a buyer who wants the Duramax turbo-diesel's torque and towing capability without paying for LT's larger touchscreen or RST's sport styling. At 305 hp and 495 lb-ft, the diesel trades peak horsepower for pulling power the 2.7L TurboMax doesn't match, plus a meaningful fuel-economy advantage on longer hauls. It's optional here, not standard — a buyer has to spec it rather than order around it, which is worth confirming on the build sheet before assuming it's included.

Custom also carries additional style and convenience content over WT, though Chevrolet doesn't publish every line item separately from the base trim — a Jim Cook Chevrolet sales consultant can walk through the exact delta between a WT and Custom build sheet side by side, which matters more than a general description once real options start stacking up.

The base for Custom Trail Boss

Buyers cross-shopping the off-road-equipped Custom Trail Boss should know it's built from this trim's content level, not LT's — so a Custom buyer who later wants the lift and all-terrain tires without upgrading to LT-based trim can step directly to Custom Trail Boss instead. See the Custom Trail Boss guide for the full off-road spec.

Frequently asked questions

Does Custom come with the diesel engine standard?

No — the Duramax 3.0L turbo-diesel is available as an option on Custom, not standard. The 2.7L TurboMax turbo-four is the standard engine unless the diesel is specifically ordered.

What's the difference between Custom and Custom Trail Boss?

Custom Trail Boss adds Chevrolet's off-road package — a factory suspension lift, 33-inch all-terrain tires, underbody skid plates, and an available locking rear differential — on top of Custom's base content. It's a separate trim, not an option box on standard Custom.

What size touchscreen does Custom have?

The 8-inch diagonal unit, the same as WT. The larger 13.4-inch touchscreen with Google built-in starts at LT.
